Resolution : 4k

The Samsung Q8F / Q8 is a 2018 QLED TV with great picture quality, especially in a bright room due to the high peak brightness and excellent reflection handling. It performs very well for any usage with great motion handling, an excellent response time, and very low input lag. Unfortunately, the image loses accuracy when viewed at an angle and the gray uniformity is only decent.

Note that this is a different TV to the 2017 QLEDs such as the Q7F and Q8C. The 2018 Q8FN is also called Q8F or Q8.

See our recommendations for the best 4k TV.

Pros
  • Excellent wide color gamut
  • Feels responsive due to low input lag
  • Great motion handling
Cons
  • Picture quality degrades at an angle
Update 6/11/2018: 1440p @ 120 Hz input lag has decreased as of firmware 1103. The review has been updated.
Update 6/8/2018: FreeSync has been tested and the scores have been updated.

Samsung Q8FN Design Picture
Curved : No

The design of the Samsung 2018 Q8 is great. It has a very modern look with sleek lines and a nice finish. The legs are solid and wide set, but they might not fit on some tables. It includes the same excellent cable management system found in the NU8000. The TV does not include the OneConnect box found on the higher-end Q9FN. The connections are all side-facing but in the TV frame, so it is difficult to reach the connections when the TV is wall-mounted.

Stand
Samsung Q8FN Stand Picture

The stand is sleek and modern. The stand feels solid and well built. The legs are set far enough apart to put a soundbar directly in front of the screen, but they might not fit on some tables.

Footprint of the 55" TV Stand: 9.7" x 38.1"

Back
Samsung Q8FN Back Picture
Wall Mount : Vesa 200x200

The back of the Q8FN is nearly identical to the NU8000. It has the same cable management system which works exceptionally well for guiding all of the cables either through the legs or through the bottom of the TV when wall-mounted.

The inputs are all inset into the back of the TV and are difficult to reach if wall mounted.

Borders

Borders : 0.51" (1.3 cm)

The frame of the TV is thin, there is a very small gap between the edge of the frame and the first pixels, but it is not noticeable.

Thickness

8.5 Build Quality
Samsung Q8FN Build quality picture

Excellent build quality. There are no gaps in the construction. It is mostly plastic but there are some metal parts. It feels well built and solid. The back panel has a lot of flex in the middle where the VESA mounts are located, and the corners of the bezel are slightly cracked but this should not cause any issues.

Picture Quality

The 2018 Samsung Q8F QLED TV has great picture quality. It has an excellent native contrast ratio with really deep blacks, and the full array local dimming feature is able to boost the black levels for great dark room viewing. Real scene brightness is good, and small highlights stand out really well. HDR highlights are extremely bright and are able to surpass the 1000 cd/m² target for HDR content. Like all VA panels it has a narrow viewing angle, but it has excellent reflection handling which is great for a bright room. The color management system is not very effective, but with the proper settings colors are accurate for most people. The Q8FN has an excellent color gamut, and has the best color volume we have ever measured.

Decent local dimming on the Q8FN, very similar to the Sony X900F. The Q8FN does not completely turn off zones that were far away from our test dot. The Q8FN has less visible blooming than the X900F, but the black levels are not as deep.

Very good brightness with HDR content. Small highlights are hitting the target 1000 cd/m² that HDR is mastered for. The screen brightness dips considerably with very bright scenes, but is still good for a bright room. Similar brightness to the LG C8, but with brighter highlights in very dark scenes, as shown by the small window tests.

The Samsung Q8 has a poor viewing angle, the picture quality degrades when viewed off angle. Blacks turn gray and colors shift even with a small angle. This TV is not a good choice for a room with side seating or even with a large couch. These results are typical of VA-type panels. OLED panels like the LG C7 have much better viewing angles.

Great black uniformity. We disabled the local dimming feature in the hidden service menu to get an accurate test. Without local dimming there is some clouding visible around the cross, but dark room viewing should still be great for most people.

With local dimming on max there is less clouding around the cross. The full array local dimming is effective at turning off zones.

This is a significant improvement over the 2017 Q8F/C, as it was edge-lit and could not fully disable the dimming zones around the test cross, which causes lots of vertical blooming.

The 2018 Q8FN has excellent reflection handling. Reflections are well defined but at a much lower intensity, as such there is much less glare. The anti-reflection coating gives reflections a slight purple tint, but this isn't really noticeable. This TV is excellent even for a very bright room.

Sub-par color accuracy out of the box. The best settings pre-calibration are with the Movie picture mode. Even in this mode, the Gamma does not tracking our target, and both white balance and color dE are too high. The color temperature is too warm, colors are shifted with more of a red-yellowish tint.

What it is: The color temperature is a measure of the color of light. A colder color temperature (7000K) will look bluer and a warmer color temperature (4000K) will look yellower/redder. 6500K is the standard color temperature use in the TV and film industry as program, film, and photography directors usually work on monitors calibrated on the 6500k color temperature and do their color correction base on what they see on those monitors.
When it matters: To get the most accurate picture when watching TV shows, movies or video games. This is particularly for skin tones.

After calibrating on the Movie picture mode, with color temperature set to 'Warm1', white balance is corrected and the color temperature is much closer to our target. Gamma follows our target curve perfectly. The color space settings are not very useful and it was not possible to fully correct color accuracy, although it is good enough that most people won't notice.

Excellent wide color gamut. The Q8FN can display nearly 100% of the P3 color space, and has the highest Rec.2020 coverage we have ever seen, although it is very close to the 2017 Q9F.

The Movie mode follows the PQ curve almost perfectly until it rolls off at the TV's peak brightness. The Game EOTF curve also follows our input closely, which is good.

Pixels

Great motion handling on the Samsung Q8FN. The backlight does flicker, but with normal viewing, it is at a high refresh rate and should not be noticeable. It has an excellent response time and supports 120 fps motion interpolation even in game mode. The backlight adjusts depending on the content played and options selected, so there are fewer motion duplications. It is very good at removing 24p judder, but wide-panning shots at 24fps stutter due to the excellent response time.

The Q8FN uses PWM to dim the backlight, and it flickers regardless of backlight setting, even at 100%. The flicker changes considerably depending on settings. Normally, it flickers at 480 Hz, which shouldn't be noticeable and creates little motion duplication. This is much better than last year's Q8C, and almost as good as Sony's X900F.

When in 'Game Mode', or if 'Auto Motion Plus' is enabled, the backlight changes to a 120 Hz flicker which is more noticeable. When we sent a 1080p 120 Hz signal, the backlight changed to 360 Hz.

The Samsung Q8FN has an optional BFI mode called 'LED Clear Motion' that adjusts the flicker depending on the content to help motion appear more clear.

The Samsung 2018 Q8FN has a 120Hz panel, and can interpolate lower frame rate content up to 120 Hz. This helps motion appear much smoother, but it can sometimes get it wrong and cause motion artifacts. In scenes with lots of motion the TV stops interpolating, preferring to maintain quality similar to the LG C8. This effect can look strange to many people and is also known as the 'Soap Opera Effect'.

Interpolation is activated by setting 'Auto Motion Plus' to 'Custom'. The 'Judder Reduction' can be adjusted for low frame rate content, and the 'Blur Reduction' slider can be adjusted to help clear up motion on 60 fps content.

The flicker changes to 120 Hz when 'Auto Motion Plus' is enabled as seen here

The Samsung Q8FN does not support FreeSync from our Radeon RX 580 GPU. We tried multiple combinations of 'Game Mode', 'PC Mode' and different refresh rates but FreeSync was never detected as supported.

Update 05/23/2018: Firmware version 1103 has added Freesync support. We are currently testing it and will update the review shortly.

Update 06/08/2018: FreeSync has been tested and the score has been updated. FreeSync was supported from our Xbox One S and our Radeon RX 580 GPU, in 1080p, 1440p and 4k resolutions. FreeSync is activated by enabling the TV's Game mode and FreeSync settings; PC mode is not required. We tested in Ultimate mode because it has the widest range, and we only recommend Basic mode when you experience problems with Ultimate.

1440p @ 120 Hz: 10.0 ms

Excellent low input lag across all input resolutions and refresh rates, as long as 'Game Mode' is activated. The 1080@120 Hz input lag is exceptionally low, which is great for Xbox One X gamers, as the Xbox One X will soon support 120Hz @ 1080p and at 1440p.

2018 Samsung TVs including the QLEDs and the NU8000 support 'Game Motion Plus', which interpolates lower frame rate games up to 120 Hz while in 'Game Mode'. This feature causes a small increase in input lag. When interpolating up to 60 Hz input lag is 20.8 ms, and when interpolating up to 120 Hz it is 26.6 ms. This is still low and most games should feel responsive.

The NU8000 and the Samsung 2018 QLEDs added support for Auto Game Mode. When it is enabled from the input menu, the TV will automatically switch to Game Mode when it detects a game being played on a console. We tested it on a PS4 and Xbox One S and it worked perfectly.

Update 06/08/2018: The input lag with VRR has been tested and added to the review.

Update 06/11/2018: 1440p @ 120 Hz performance has improved as of firmware version 1103. The 1440p @ 120 Hz input lag is now 10.0 ms, down from 25.0 ms.

Most common resolutions and refresh rates are supported without issue. Like the NU8000, the Q8FN does not support 1440p@60Hz, and in PC mode with a 1440p@120Hz signal the TV does not display chroma 4:4:4 properly, as colors appear washed out.

Unlike last year's Q8C and other 2017 Samsungs the Q8FN supports 120Hz input.

The frequency response of of the Q8FN is below-average. Low-frequency extension (LFE) is at 76Hz, which is quite decent for a TV. This means that this TV will be able to produce some punch and kick, but no thump or rumble in the bass range. The response above the TV's LFE is decently flat and well-balanced, but because this TV doesn't have a room correction system, it wasn't able to remove the modes of our test room around 200Hz. The Max SPL of 85.5dB is above-average, but may not be enough for loud environments.

Differences between Sizes and Variants

We tested the 55" (QN55Q8FN) version FA02. For the most part, we expect our review to be valid for the 65" version (QN65Q8FN) and 75" version (QN75Q8FN).

In the UK, Samsung will be releasing both a curved variant and the flat version of the Q8FN. Both of these are edge-lit TVs and will not feature Full-Array Local Dimming. While we will not be reviewing the UK variant, we expect the performance to more closely match that of the Q7FN, which we will review in the coming months.

If someone comes across a different type of panel or if their Samsung Q8FN doesn't correspond to our review, let us know and we will update the review.

Update 07/06/2018: We estimate our 55" model to have 40 local dimming zones. There was initially a rumor that the 65" model has many more (240) however this doesn't appear to be true, so we do expect these larger sizes to offer similar dark scene performance.

Compared to other TVs

Bottom right: Sony A8 (XBR55A8F).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Samsung Q8FN is a strong performer in both dark and bright rooms. It is great for any usage but comes at a very high price. See some of our comparisons below for how it compares to other TVs on the market.

Samsung Q8C
55" 65" 75"

The Q8C from 2017 is the curved predecessor to the Q8FN. Both TVs can display very saturated colors in HDR content but the 2018 model has an improved full-array backlight. This allows it to get brighter, it also has much better local dimming which helps to produce deep and detailed dark scenes. The 2018 model also supports 1080p @ 120Hz, which is great for gaming. The Q8FN does not have a OneConnect box, so it is slightly less convenient. Overall the Q8FN is a better TV for any use.

LG C8
55" 65" 77"

The LG C8 is one of their latest OLED TVs for 2018. It has exceptional picture quality since the OLED panel is capable of producing true blacks with an infinite contrast ratio. Compared to the Q8FN the C8 is not as bright with SDR content, and HDR highlights do not pop as much. The C8 remains more accurate when viewed at an angle which is good for wide seating. The overall best pick will depends on preferences and use - as an OLED panel, the C8 is at risk of permanent burn-in; so if this concerns you, the Q8FN is the best LED TV we have tested.

Sony A1E
55" 65" 77"

The Sony A1E is Sony's high-end OLED TV from 2017. It is a little bit cheaper than the Q8FN and the picture quality is a bit better in completely dark rooms due to the perfect blacks. It isn't as bright as the Q8FN, so it isn't the best choice for a bright room, but it has a much wider viewing angle. Like the C8 and other OLED TVs, it has an instantaneous response time which is excellent for fast motion but low frame rate content stutters, especially with wide-panning shots. The best TV depends on your use and preferences but if the possibility of burn-in is a concern, the Q8FN is a great buy. 

Sony X900F
49" 55" 65" 75" 85"

The X900F is Sony's highest end LED TV released in 2018. While the X900F is a strong performer across the board, the Q8FN is better overall. It has excellent reflection handling, which is great for those with bright rooms. It can also produce more saturated colors for HDR content, and has a few neat gaming features such as the low input lag with interpolation and automatic game mode switching. The X900F is a bit brighter than the Q8FN in both SDR and HDR, and has slightly better motion handling due to the faster response time. While the Q8FN is better, the price difference is large and most people are better off saving the money and buying the X900F.

What it is General purpose. The TV will be used for a variety of content and usages. Movies at night, TV shows during the day, video games from time to time, etc.
Score components:
Great TV for a wide range of usages. The Samsung Q8F can produce deep and uniform dark scenes when viewed in a dark room. Local dimming is also decent at reducing blooming and producing bright highlights. Motion handling is great, and the response time is fast so motion is clear. It isn't perfect though, as the image loses accuracy when viewed at an angle and some dirty screen is visible, especially when watching sports.

Motion handling is great, so fast-paced content remains clear and detailed. Unfortunately, the best picture quality is reserved for those directly in front of the TV, so those with wide seating may be disappointed.
8.9Video Games

What it is Video games. The TV will be used to play video games, directly in front, in a controlled light environment. Usually fast games, like online FPS, where motion blur and input lag is important.
Excellent for gamers. Input lag is low, so the TV feels responsive regardless of the input signal. Motion handling is also great due to the fast response time and ability to flicker the backlight to clear up motion. The TV also supports motion interpolation with low input lag in game mode, which is great for a smooth gaming experience.
8.4HDR Movies
Show Help
What it is HDR Movies and TV shows. The TV will be used to watch 4k UHD HDR content, with a wide color gamut and a high peak brightness. Either via UHD Blu-rays or HDR streaming.
Excellent TV for HDR movies in a dark room. Picture quality is great, and the TV can produce deep dark scenes with the high native contrast ratio and decent local dimming. It can also produce very bright and vivid highlights due to the wide color gamut.
8.7HDR Gaming
Show Help
What it is HDR Gaming. The TV will be used to play HDR video games using consoles that support it or on current generation gaming PCs. Xbox One S, PS4 Pro, GTX 10 series and AMD RX series graphics cards.
Excellent choice for HDR gaming. The Samsung Q8 has a low input lag and fast response time, so the TV feels responsive and fast motion is clear. Also, the TV supports HDR well with a high peak brightness and can produce bright highlights. The TV can also interpolate games while keeping a low input lag, which is great for smooth play.

What it is PC Monitor. The TV will be used as a PC monitor, from 2-3 feet away, either for productivity purposes or gaming. Sharp text is important, as well as a high resolution.
Score components:
Great choice for a PC monitor. Picture quality is good. The TV supports chroma 4:4:4 for clear text across all backgrounds, and it has low input lag so the TV feels very responsive. It also has a low response time, so fast motion is clear. Unfortunately, the viewing angles are poor so the sides of the screen lose accuracy when viewed from up-close.

How does the motion in games on the Q8FN (with Samsung's 'Game Motion Plus' settings) compare to the X900F (with X-Motion Clarity)?

There are many different aspects to motion performance which influence how it appears on both TVs.

  • The X900F has a faster response time, so there is slightly less trail following moving objects. This is visible in our motion blur photos by comparing the length of the trail on the left-hand side of the X900F (here) to the Q8FN (here)
  • The Sony X900F offers many different options on the 'Clearness' slider to adjust backlight flicker to your preference. Using 'X-Motion Clarity' (setting 'Clearness' to 1) is almost the same as the full-array 120Hz flicker when the Q8FN receives a 60Hz signal and 'Game Mode' is activated.
  • The lowest flicker frequency possible on the X900F is 120Hz. This means that duplications can be seen behind fast-moving 60Hz content on the X900F (see here). The 60Hz flicker on the Q8FN does result in clearer motion at 60Hz (see here), but also introduces very visible flicker
  • The Q8FN has the ability to interpolate content up to 60Hz or 120Hz with low input lag. This makes it suitable for gaming, and works to produce smoother motion when frame drops are present (due to graphically intensive scenes reducing the framerate of the console or PC). It can also reduce persistence blur due to the higher frame rate, but will introduce artifacts.

Overall, the best motion for gaming depends on your preferences and use.

How many local dimming zones does the Q8FN have?

Thank you for bringing this up!

We measured 5x8=40 zones. However, always keep in mind that the exact number zones is not a decisive factor in the perception of local dimming performance. Many other factors affect good performance, and remember that the overall result is always very subjective as you can read here.

Do you think the Q9FN will fair better in any category? and Would the Q8FN/Q9FN or the Sony Z9D be the best bet for hdr gaming and hdr consumption in general?

Thanks for contacting us

- The Q8FN doesn't have the One Connect box included with the Q9FN,
- The design is a little less advanced.
- It is slightly less bright (still very bright!)
- Q9FN has more aggressive blacks and is a better TV overall.
The Z9D is an excellent TV, but for your usage the Q9FN is a better choice. Although local dimming might be a little lower, as it has lower input lags, better contrast and black uniformity and …a lower price!.

4
It was noted in the Q9FN review that the local dimming algorithm was very aggressive and caused some loss of detail in dark scenes; has the RTINGS team tested the Q8FN vs the Q9FN for possible differences in dark scene performance? I'm interested to see if the local dimming algorithm is 1) shared between the Q8FN and 2) if the greatly improved local dimming contrast ratio of the Q9FN is negated by the (overly?) aggressive local dimming algorithm. From firsthand experiences with both TVs, I'm interested to see the physical advantages of the Q9FN's backlight array and software against the Q8FN's.
Unfortunately we can't really do a direct comparison here. The 55" Q8FN we tested has about 40 local dimming zones, but the 65" Q9FN we tested has about 480. There is definitely a difference in the efficiency of the local dimming, but whether this is due to a difference in algorithms or due to the number of zones, we don't know. In our side-by-side comparisons, the Q9FN is definitely a bit better in dark room viewing, as long as you don't mind maybe losing some tiny details in very dark scenes.

Hi you mentioned that the footprint of the 55" TV Stand: is 9.7" x 38.1". Does that mean the distance between the 2 legs is 38.1 inches which would fit on a 40" wide TV stand. thanks. Great job reviewing.

Thank you for you kind words!

Yes, it would fit on a 40" wide TV stand!
In fact, we define the footprint as the area which sits on the table (including the width of the legs, rather than just the area between the legs). So, in this case, the 38.1" include the legs themselves.

I wish you would include the power cord for the what's in the box picture.
This was an oversight on our part, thank you for bringing it to our attention. The review has been updated.

Hello, great review ! I wanted to clarify a few things:

  1. Is 4:4:4 chroma properly supported on the Q8FN (no washed out colors etc.) in 1080p@120hz mode ?
  2. How important is 4:4:4 chroma support for PC games ? If I were to PC game on this TV at 1440p@120hz - would the 4:2:2 affect the PC games negatively? Would it make text look worse or something else? Or its not an issue at all while in-game? Is this (whatever the answer is) universally true for ALL PC games?

As a side-question to 2. - do you know if modern consoles (PS4 (Pro) & XB1) run in 4:4:4 mode or 4:2:2 mode while playing games? Thank you.

  1. Chroma 4:4:4 is properly supported in 1080p@120Hz, colors are not washed out.
  2. Chroma 4:4:4 is not very important for PC games, most games are designed with chroma subsampling in mind or implement it in the engine. Colors may look slightly different when not in 4:4:4, but most people won't notice this. With PCs it is important especially for use as a monitor, as text looks best in 4:4:4. This should be true for most games, but we can't say for sure that this is the case for every game. Text-heavy games might suffer a bit from chroma subsampling.

    Modern consoles default to 4:4:4, but you can change this in the settings menu for each. For a 10-bit panel it should be changed to 4:2:2 due to bandwidth limitations of HDMI 2.0.

2
How does this compare to the Sony X900F? Also, are you planning on reviewing the Q9FN in the near future?
The Q8FN is definitely a better TV than the X900F, but there is a significant price difference that probably isn't worth it. We published our review of the Q9FN yesterday.
2
What is the difference between the Samsung QN65Q8F and the Samsung QN65Q9F besides the price?

Thanks for contacting us

- The Q8FN doesn't have the One Connect box included with the Q9FN,
- The design is a little less advanced.
- It is slightly less bright (still very bright!)
- Q9FN has more aggressive blacks and is a better TV overall.
Unless you want the best, the Q8FN is worth saving the money.

Would be great if you included the number of zones when reviewing FALD sets.

Thank you for your suggestion.

Our main goal is to review the end result, and since the number of local dimming zones is not directly related to better performance (as other features play a role too) we tend not to include a count in the reviews. We can start providing an estimation in the future (we do get asked more frequently) however with the disclaimer that more zones doesn't necessarily mean better dimming.

I have a 65KS8000, in game mode the brightness will fluctuate based on the scene brightness even if Smart LED is turned off. For example it will be at a certain brightness when there is something bright filling the screen, but when it transitions to a darker scene it will dim significantly. One example that really shows this is the loading screen of Borderlands which has a dark background, as the objects pop on and off the screen you can see the brightness fluctuate. In your testing have you seen this happen on the Q8FN?

The brightness of the KS8000 fluctuates depending on content. As you can see in our SDR Peak Brightness test, the sustained 2% window was significantly dimmer than any other scene. If enabled, the local dimming feature was poor and there is a lot of blooming and problems with scene transitions.

We didn't have any similar problems with Q8FN. We tested with similar dark scenes and the highlights stood out well. Subtitles and scrolling text (for example the rolling credits at the end of a movie) are bright, but there is visible blooming around the text.

Thank you for continuing to provide such detailed and informative reviews! You all do a great job. I currently own a Samsung KS8000. Would you consider the Samsung Q8FN or even the Sony X900F a big step up from that or only marginal differences? Would it be worth upgrading? My usage and conditions include movies, HDR movies, TV shows, and some video games. I am about 7.5 feet away with a moderately lit room. I would like to stay in the 55" range and not have to worry about potential OLED burn in. Thank you

You're not likely to see a huge improvement with either of them over the KS8000 for your usage. They both have a full array local dimming feature, which would improve dark room viewing, and the X900F is brighter in HDR, but other than that all 3 are very similar TVs.

1
How does it compare to the KS 8000 from 2016?

The KS8000 was last tested on Test Bench 1.0, so it is impossible to do a direct comparison of the scores. The Q8FN has an added full array backlight, which results in a better local dimming feature which makes it better for dark room viewing. It is also a bit brighter, though not enough to make a huge difference. The Q8FN also doesn't have the mini one-connect box.

I am wondering about the results for the Samsung QLED line and their viewing angle score. I have great results with my 2018 55 inch Q8FN. I only get noticeably worse results when I switch to movie mode with lower brightness. I wonder if this means that a calibrated TV with duller colors isn't engaging the quantum dot layer as much and missing out on some benefits?

I look at it like these TVs have an excess amount of color and brightness that if some is lost at an angle you hardly notice? I wonder if you would want to check how picture settings might affect viewing angle performance.

I had the LG B7 and I prefer the Q7 for a few reasons: no burn in risk, more apps and better interface, wifi performance, one connect with no gap wall mount(undervalued and only maybe bested by the LG W series), brightness and color.

Again, I personally feel the QLED series has much better viewing angles than other LCD TV's with VA panels. Thanks for all your hard work and great information.

Picture settings don't directly impact the viewing angle, but some things like brightness can affect your perception of the viewing angle. For example, TVs like the Sony X930E, when the brightness levels are boosted the perceived brightness drop at an angle isn't as noticeable. What you are seeing when switching to movie mode is probably due to the brightness drop.

The LG B7 is a great TV, thanks for your comments on the Q7.

Manufacturers have a lot of tricks to help reduce the perceived effects of viewing angle, our tests are designed to ignore these tricks and to objectively measure the viewing angle of the TV.

Hello Rtings! Just want to say I love the extensive work you guys put into these reviews.

I noticed there was an issue when enabling "PC mode" for any input on my 55Q8FN. Upon enabling PC mode, it makes the whole picture slightly blurrier. Ironically enough, I noticed that the picture was blurrier through fine text such as desktop PC icons. I also noticed a blurrier image in finer details such as native 4K games. I was wondering if you guys noticed any issues when switching any input to PC?

Glad you enjoy the site!

On the Q8FN (really all the 2018 QLEDs), the true no sharpness setting is 10. When changing to PC Mode sometimes the TV will keep the same sharpness setting as out of PC Mode, but this is wrong. Most people will set the sharpness to 0, but that setting is actually softening the image.

We've added a note in the settings page to clarify this.

I know in the information tab you list that the score for local dimming is subjective, but there seems to be a great difference between the two TVs I am researching, yet you give them the same score. 7.0.

On the X900F it seems that when the local dimming is on, we get about a 7% boost in contrast compared to its native contrast.
On the Q8FN it seems we get about a 47% boost in contrast compared to its native contrast.
On the X900F it seems that when you activate local dimming, you actually lose black uniformity.
On the Q8FN it seems that when you activate local dimming you actually gain black uniformity.

Both a 7.0 for local dimming?

Thank you for contacting us.

Part of the difficulty with objectively assessing the local dimming performance is the significant number of impacts that the local dimming algorithm has. The local dimming of the X900F (when combined with X-tended Dynamic Range) boosts highlights, which makes them stand out more and it also reacts more quickly to scene changes. On the other hand, the local dimming of the Q8FN is more conservative - it doesn't dim small dark areas as much but it also doesn't boost highlights. Depending on your preference either of these may be preferable.

What are your guys thoughts on this TV vs the KS9800 full array, or the 2017 Sony X930E?

While we didn't review the KS9800 with FALD, we expect it to be similar to the KS9500, obviously except for the local dimming feature. All 3 TVs are similar, offering similar versatile performance with great brightness and native contrast. In the end, the X930E is brighter than the other two and is cheaper, but they are all great TVs.

You state the 55" Q8FN shows the zone count at around 40 zones, most other review sites are reviewing the 65" version and stating over 200 zones. Wouldn't a zone count that drastically different affect your review? Are you planning on testing a 65" Q8?

Thank you for bringing this to our attention. We have added a note in the "Sizes and Variants" section of the review.

While this will have an impact on the local dimming score, it won't significantly change our scoring. For comparison, the 65" Q9FN we reviewed has 480 zones, and it scored an 8.0 in local dimming. The number of zones is not as important as the algorithms that control them.

0
Are you sure it's 40 Zones? The 65" model is said to have 240 zones and I don't see such a dramatic difference between the 55" and 65" models.

Yes, the 55" model has 40 zones. We have added a note to our variants section. Note that this will not have a significant impact on scoring. The number of zones is not as important as the implementation of the control algorithms.

Great tv for what it is. I am curious on how this will compare to the new Vizio P series quantum. Any idea if and when you may get the new vizio to compare? As always thanks for all the work and info!

Thank you for your support

The Vizio P Series Quantum launch is certainly highly anticipated and is currently one of the top ten in our TV suggestion list. We will most likely review it shortly after it becomes available in the summer.

Is there a closer/alternate position for the stand legs similar to the 65KS8000?

Thank you for contacting us!

The model we tested was the 55" and there were no alternate position for the stand legs. We also looked at the TV specs and we could not find anything there either. However, in Samsung models where alternate positions for the stand legs were available, like the 55" MU8000, nothing is mentioned on the specs sheet!

I wanted to add some information that may be of use to VA panels and image burn. I've worked with Best Buy for a few years, and I've noticed significant image burn on our 2017 shelf display Sony 940E starting about 6 months into it's display life. I've noticed it on other very bright Full Array TVs as well and think that you should retest image burn on very bright Full Arrays to get a more accurate accounting of how all premium TVs (since practically all of them are moving to either Full Array or OLED) handle image burn.

Thank you very much for your contribution!

We are currently running the 20/7 Burn-In Test, in which we include a VA panel (Samsung KU6300) with pretty good results so far. Of course it is not a FALD TV (in fact there is no LD option at all.) After the test is completed we might decide to run a test on a FALD TV to see how it performs in the long run. Thank you for your suggestion!

Any idea how many zones the local dimming have on the 65". I am hearing 240 but based on the performance of my TV it looks like almost none. My TV acts like an edge lit TV and not a FALD.....Unless there is something wrong with the panel. Thank you.

Thank you for your question!

We only tested the 55", and were able to measure about 40 zones. We are aware of the claims of 240 zones, but we do not have a unit to test and give you a definite answer. Our set performed ok in local dimming, so it might be a problem with your panel. You can try to test your TV and measure it's local dimming zones using this.
Let us know how it went.

How can you rate the Q8FN under the C8 in HDR Gaming while besting it by almost 40% in 4k@60Hz+HDR input lag (25% of score), and scores 18/20 compared to 20/20 on contrast & response time (23% score)?

The difference between the two is almost negligible, keeping in mind that our scoring system is not linear (I.e. a 10% difference in the results does not translate to a 10% score difference). The lower 4k input lag makes a 0.2 difference in score between the two. This is offset by other advantages of the C8. For example the improved response time makes a difference of 0.15 and the better contrast makes a difference of 0.08 in the score. Adding up all of these tiny differences results in the C8 being a slightly better TV for HDR Gaming. In reality, both are great TVs for HDR Gaming and there likely won't be much of a difference between the two.

Hope this clears things up!

I'm looking to spend around 4k been looking over the last 2 years. I will be in a medium light room with straight viewing angles. I have liked the 75" q7f but my other choices would be either 65"q9fn or the 65" q8fn. I think bang for the buck the 75" is the way to go but I would like your opinion for overall best quality. Thank you Jason

Thank you for contacting us.

You are only mentioning Samsung models so we will constrain our answer to these. We're also assuming that the Q7F you are referring to, is the 2017 model that we have reviewed and not the 2018 model.
Generally if someone is interested in two TVs of similar performance and cost, but of different sizes, we favor the larger one, provided the viewing distance is adequate.
In your case, however the Q8FN and the Q9FN are a better choice, mainly due to Q7F's poor local dimming performance and average black uniformity. The Q9FN is a better TV overall, but the Q8FN is close enough and it will save you some money. If you've already waited 2 years you might as well wait a little longer and get the 75" model at around the price you looking to spend.

You mention the Q8FN’s local dimming is better at blooming than the X900F but doesn’t produce as deep blacks. However, the contrast ratio with local dimming is much higher on the Q8FN. Could you clarify the statement that the blacks are not as deep? I know you don’t do zone estimates, but do you have an idea if it has more or fewer zones than the X900F? I realize zone count matters less than how well it handles local dimming overall, but I’m just curious. :)
When the Q8FN shows a dark scene around a bright highlight, it fades out the backlight zones gradually as they get farther from the highlight. This creates some blooming, but the black levels aren't as deep. On the X900F the zones are turned off as close as possible to the bright highlight. While only an approximation, the 55" X900F and Q8FN both have about 40 dimming zones.

Just got my new 65Q8 2018 TV yesterday.
Had few issues you did not mention in your review probably because your set was in a better shape than mine. Letterbox bars are not black. Kind of gray. Minor light bleed into the bars during bright scenes. At times in seems that the local dimming does not work at all. When there is a light in the corner of the screen, almost a half of the screen next to it lights up which looks really bad in dark scenes. Also, subtitles light up the whole bottom part of the panel. Brightness fluctuations almost pulsating especially in dark scenes.
I wonder if this is only my panel or issues with these TV’s. Some on the AVS forum mentioned similar issues.
Thank you in advanced.

Thank you for contacting us!

Can you check that you are running the latest firmware version. When we tested our unit we had to update twice. Samsung claims that having the latest firmware is crucial to local dimming performance. Even though, local dimming is not one of this units' strongest points, the situation you are describing is not what we experienced. Yes we did notice that the TV does not turn off zones far from the test dot, but not half of the screen. Try running the zone counting test on your TV to test your panel, but keep in mind that different panels can have different performance, and that perception of blooming is very subjective and scene specific.

Let us know how it went.

You say in the Q8FN review that the X900F has better blacks. You also scored the Q8FN higher in contrast and black uniformity, both native and with local dimming.
How does the X900F have better blacks?

Thank you for contacting us!

The two TVs handle local dimming differently and that's where 'better blacks' comes from. The local dimming of the Q8FN doesn't turn off zones completely to produce blacks, as it prefers to reduce visible blooming. On the other hand the X900F has more aggressive local dimming which produces true blacks, but with more blooming.

I notice that all these new Samsung TVs don't pass DTS via ARC or optical. There are UHD Blu Rays that only include a DTS English track. The Dolby tracks are in other languages. What happens if I play one of these discs, play the DTS English track and have a sound bar hooked up to the TV's optical out?
In this case, it highly depends on your setup. Some players are able to convert DTS to Dolby Digital(although conversion won't be lossless). If your player isn't able to convert to Dolby then they audio will be converted to PCM. To be safe, your best bet would be to connect your player directly to your soundbar.

Hello, I wanted to know if you found that using PC mode on the Q8FN introduced any extra blurriness ?

I saw this post from an owner on forum about blur problems with Q8FNs PC mode (no pictures here, but they did show that one mode is clearly blurrier/less sharp than the other and according to the poster - its the PC mode thats blurry):

-------------------------------------------------

Has anyone one else noticed that text is blurrier in PC mode? I'm not sure why, as I thought that mode would be optimized for text (Chrome 4:4:4 enabled).

I took some pictures and the clearer text is actually in the regular Game Console (Game Mode enabled) input vs when the TV is set to PC mode (Game Mode enabled).

Is this a TV issue? The first pic is from the regular Game Console input setting, and the second one is from PC mode. The photos aren't 100% lined up, but you can tell by the bezel clarity that they are both in focus to the same degree.

EDIT: I just noticed putting the TV in PC mode makes EVERYTHING slightly blurry. I was playing DOOM on PC in native 4K in PC mode and was staring at the fine details on the pistol, and noticed it didn't look quite right. When I switched the input name from PC to Game Console, I immediately noticed that the pistol became sharper! No changes were made to the sharpness value at all (0 for both modes) nor other changes to effect picture quality (same resolution, brightness, etc). I think there is a bug with the PC input...

--------------------------------------------------

This seems weird and the opposite of how it should be ? (PC mode 4:4:4 should be sharper, no ?)

Thank you.

We retested PC mode on the Q8FN, and it is displayed properly without any blur. The blur they are seeing in that thread is due to the Sharpness setting. On the Q8FN in PC Mode only the true no sharpness setting is 10. We tried it with a setting of 0 and were getting the same blur they are seeing.

We've added a note on the settings page to clear this up.

There have been a plethora of other people who have tested this TV and have done zone testing, and have all concluded it has over 200+ dimming zones. Am I missing something?

The 55" we tested has about 40 zones, but the 65" has about 240. Just to note though, a TV with more zones will not necessarily have better local dimming, there are other factors involved.

What do you recommend buying between the 65 inch C8 and the 65 inch Q9? Also do you know any warranty company in the US besides Best Buy that covers burn in? Having a hard time making a decision on this high-end TV to purchase my room is not very bright and can be dark as I do like to keep my blinds closed but lighting situations aside If you were going to buy one for yourself which would it be?

Assuming you are referring to the 2018 Q9FN, go with the C8 unless burn-in concerns you. With the Q9 is definitely an amazing TV, the C8 is better, especially for dim/dark room performance. We would like to point out that the B7 is also an excellent choice, there really isn't much difference in performance between the C8 and B7.

For OLED TVs the only warranty we know of is with Best Buy. Samsung guarantees their QLEDs to be free from burn-in for 10 years, but they shouldn't experience burn-in to begin with.

Since your review on the new QLED Q7FN disappointed me in respect to black level in a dark room I wondered what your best guess was for how low this QLED Q8FN price will drop, be it Christmas, Black Friday, etc.
Unfortunately we don't really know, pricing strategies vary from year to year and it is up to each retailer to set their pricing. Based on the 2017 Q8F, last year it went as low as about $1300 below the initial launch price by Black Friday, but again, some retailers may have sold it for less.

So this will be the 2nd or 3rd question I've asked you guys haha. I'm replacing my Panasonic ST60 and have it narrowed down I think to the Q8FN, X900F and the X940E. I'm aiming for 75 inches (if the Q6FN is worth it I'd go for 82"). I mostly watch streaming services and physical media plus game on the weekends.

The X940E and X900F intrigue me for film, especially the contrast on the 940E. But the Samsung has less blooming than the X900F which coming from a plasma may be very important but I don't know if the blooming is even all that bad on the X900F (flip side is the X900F has deeper blacks despite the lower contrast).

Motion on the 940E is a bit of a turn off. However the gradient is lower on the Q8FN (is that honestly something I would even notice?). I will say when comparing 1080p Netflix content on my ST60 to my KS8000 such as Moana, night time scenes just don't look as good - the sky is bright and kind of dull whereas on the plasma its amazing. Would I have that issue on any led or is it just the KS8000 being edge lit? Sorry if I'm all over the place. I just want to make sure I make the right decision. Thanks!

Wow, sounds like you already have a pretty good grasp of the advantages of each of them!

The X940E would probably not be a good choice due to the motion handling. For movies it isn't much of an issue, but for gaming the high response time causes long motion trails in fast changing scenes.

Between the Q8FN and X900F, they are both great choices depending on what is most important to you. First of all, if you want larger than 75", go with the X900F as it is available in 85". For most people the Q8FN is better, but the X900F has a better viewing angle and better motion handling.

Both of these TVs have a better local dimming feature than the KS8000, and in night scenes like in Moana there shouldn't be as much of an issue. The sky is bright in that scene because of the edge-lit local dimming, the TV can only dim columns, so if it is dark at the top and bright at the bottom the whole column will be lit.

0
How many dimming zones does the Q8FN have?
The 55" model has about 40 zones, and the 65" has about 240 zones. Note that the number of dimming zones does not necessarily translate to better local dimming.
0

Great reviews as always. Any chance Samsung will fix the issue about not completely turning off zones that were far away from your test dot?

Seems that would greatly improve the black levels.

It's possible, and we have seen Samsung adjust local dimming algorithms in the past. We will continue testing the TV with each firmware update until it is discontinued.

Would you have any idea how the screen reflections on this TV would compare to a 10 year old Pioneer Elite Plasma TV? I have the TV in a fairly bright room, and want to make sure a new TV would be better from a reflections point of view. Thanks very much for your thoughts.

Thank you for contacting us.

Although we can not compare your TV to the Q8FN we expect the Q8FN to perform better because in the last 10 years there have been several advancements in reflection filters and also because the Q8FN is one of the best performers regarding reflections.

I have an employee purchase program for Samsung through my work. I can get the Samsung Q8FN for the same price as the Sony X900F currently. I know that through the recommendations, based upon your recommendation chart it shows the X900F slightly ahead of the Q8FN based upon my needs (medium bright room, primary use for Sports and Movies, no gaming, 65 inch model, etc.).

Would the recommended TV with this price difference still reflect the same or differently? I'm essentially looking for best picture quality and motion for watching hockey and baseball and best HDR for movies for my price range and these 2 TVs seem like the best logical fit. Thanks so much for your help in advance.

For your particular usage the Q8FN is actually slightly better. For sports the Q8FN has a 8.2 compared to 8.1 for the X900F, and for HDR movies it scores an 8.4 compared to 8.3 for the 900F. There isn't a huge difference and normally we wouldn't recommend the Q8FN over the X900F but for the same price it is a bit better.

I saw a comparison with the Sony 900F, but if one can still put purchase the 930E, would you recommend the Q8 or go with the 930E?
The Q8FN would be the best choice if you plan on using it in a sports or gaming context, as it has a shorter response time than the 900E and better motion handling with its lower minimum flicker at 60 Hz.

Do you have any information on the footprint of the stand of the 65 inch model?
We did not review the 65" version of the Q8FN, but from what we could find online, the footprint of the 65" Q8FN should be around 11.6" by 44" wide.

Both the Sony X900F and the Samsung Q8FN offer some new features for gamers. The X900F can do BFI in game mode with little brightness penalty and the Q8FN can do motion interpolation and BFI in game mode.

How would you compare the two TVs at handling motion in game mode? I play a lot of HDR games so I’m looking for something that handles motion well without taking a hit to peak brightness.

I’ll be coming from a KS8000 so I expect both will be improvements in motion.

Overall, the Sony X900F has better motion handling than the Samsung Q8FN, but both are an improvement over the KS8000. The X900F has a faster response time than both of the Samsungs, and is almost flicker-free. The Q8FN has a better black frame insertion feature, since it can flicker as low as 60 Hz in game mode for 60 fps content, but this will have a significant impact on the peak brightness. Since you don't want to reduce the brightness of the screen, the less powerful BFI mode on the X900F and the better overall motion handling makes it a better choice.

I'm currently trying to decide between the 75" Samsung Q8FN and the Sony 85" X900F. I'll be able to get a 20% discount with the Samsung, but for the Sony I'd have to pay full freight. What's the better option if I have mixed usage with 75% streaming (Plex, Netflix, Amazon Prime) from an Apple TV 4K and the other 25% gaming from a PS4 Pro?
Based on your usage, the Samsung Q8FN is a better choice. The Sony X900F handles motion better, but the Q8FN has better input lag, and is better overall. Normally the differences are not worth the price difference, but with 20% off the Samsung Q8FN becomes cheaper than the X900F.

Is the 75" QF8N worth the ~$500 price increase over the QF7N? The one connect is nice, but not required as I plan to use the stand vs wall mount. I am mostly interested in picture quality for sports, movies, and general DirectTV...thanks!
The Samsung Q8FN and the Samsung Q7FN are very similar models in terms of picture quality. The main difference between these two models is local dimming performance. The Q8FN has decent local dimming with full array backlight which performs considerably better than the Q7FN. We would recommend going with the Q8FN if you plan on using the TV in a dark room as it has better dark scene performance, but otherwise you might be better off saving the money. We would also recommend the Sony X900F as it performs very similarly to the Q8FN at the cost of the Q7FN.

I read in your review that the Q8FN has a trailing ghost for sports, and I would find those ghosts to be extremely distracting. My main goal is for sports, should the ghosting be a deal breaker for hardcore sports fan? I want to go with this option due to the lower burn-in risk but seeing vapor trails for sports figures would be too much of a trade off.

This is a great TV for sports fans! Like all TVs there is a small amount of motion blur(as seen in our motion blur photo) that follows fast moving objects, but on the Q8FN you would have to be very close to actually see it. This definitely is not a deal breaker for sports fans. The bigger issue is the limited viewing angle, since the best picture quality is reserved for those directly in front of the screen.

Vincent Teoh of HDTVTest mentioned that the Q9FN does not track the HDR EOTF curve correctly. I see that in the review of that set you were able to replicate the issue and posted some settings that could alleviate the problem. I was wondering if the Q8FN exhibited the same issues. I know that in Europe the Q8 is an edge lit model and different than what we get in North America so sites in Europe won't be able to provide this comparison. The Q8 is on my short list of prospective TVs and this info would be useful. Thanks!

The Q8FN's HDR EOTF behaves similarly to that of the Q9FN, but its over-brightening is not as severe: when the TV is sent a 10,000 cd/m² HDR infoframe the EOTF tracks the target PQ curve nicely, but when sent a 1,000 cd/m² infoframe the EOTF over-brightens bright shades, like the Q9FN does but not as bad. This is mostly fixed by either setting the 'Gamma' slider to -2, or setting the 'Contrast' to 45.

Many current HDR movies are mastered for 1,000 cd/m² and will show over-brightening, however some are mastered for 4,000 cd/m² and will show far less brightening, as was likely the case with the Mad Max Fury Road clip HDTVTest showed in their video.

Another thing to note is that many people find HDR over-brightening desirable when watching content in a bright room, because HDR is usually mastered for dark room viewing.
