Good value: IPS maintains good color accuracy at an angle, but has a poor contrast ratio from in front. VA has great picture quality in front, but loses saturation at an angle. OLED maintains good color accuracy at an angle without any of the other issues seen with IPS and VA, as they keep good brightness and contrast at an angle.
:
VA
Resolution : 4k

The Samsung Q7F is a 2018 4k QLED TV with great picture quality. It can produce saturated highlights in HDR content due to the very wide color gamut. It also has great bright room performance as the whole screen can get very bright and it has excellent reflection handling. Unfortunately, when viewed in a dark room, the local dimming isn't very effective at producing deep blacks and for those with wide seating, the best picture is reserved for directly in-front of the TV.

Note that this is a different TV to the 2017 QLED Q7F. The 2018 Q7FN is also called Q7F or Q7.

Score components: Subjectively assigned
Samsung Q7FN Design Picture
Curved : No

The design of the Samsung Q7FN is excellent and up to par with last year's Q7F. It comes along with the OneConnect box incorporating some improvements over last year's design. The cable that connects the box to the TV is very long (195") and it also provides power thus eliminating the need for an extra power cord.

Stand
Samsung Q7FN Stand Picture

The stand is quite stylish and sturdy and resembles last years Q7F. Although the TV wobbles a little bit as with most center stands, it is well balanced and should please most people.

Footprint of the 55" TV stand: 33.5" x 11.4"

Back
Samsung Q7FN Back Picture
Wall Mount : Vesa 200x200

The back is plastic with small grooves and a matte finish. It looks very much like last years' Q7F. There is practically no need for cable management channels due to the OneConnect box, here.
This also facilitates wall mounting, but at the same time requires planning for the placement of the OneConnect box.

Borders

Borders : 0.35" (0.9 cm)

The borders of the Samsung QN55Q7FN are very thin with a metal finish. They look nice and are very similar to the 2017 Q7F.

Thickness

The Samsung Q7F gets warm, but not excessively warm. The heat picture reveals that the TV is warmer towards the bottom of the screen where the LEDs are located. The yellow spot on the lower right side of the image is the OneConnect box that reaches a maximum temperature of 100° F. These temperatures are well within the norm and should not cause any problems.

The build quality of the TV is great. There are no obvious gaps in the unit. It is mostly plastic, with some metal parts, including the stand and the borders, which contribute to its solid feel.

Picture Quality

The Samsung Q7F 2018 produces great picture quality. It has an excellent native contrast ratio and black uniformity, so it produces deep dark blacks great for dark room viewing. It is edge-lit and has a very limited local dimming feature. It is extremely bright with excellent reflection handling, making it a great choice for bright rooms too. Like all VA panels, it has a narrow viewing angle. It has the widest color gamut ever measured, and exceptional color volume, so HDR movies look very close to what the creator intended. It has limited gradient reproduction, and large areas of similar colors could suffer a bit (this is especially noticeable in shots of the sky).

The contrast on the Samsung Q7FN is superb. It's about 20% higher that the 2017 Q7F. When set in a dark room, the Q7FN can produce deep black scenes.

When measured with local dimming activated, there is almost no change due to poor performance of local dimming.

The local dimming feature on the TV is bad. Performance is very similar to the NU8000. It focuses on the moving highlights, but the rest of the screen is hardly dimmed. It was a bit noticeable when the highlights were at one edge of the screen.

The TV has excellent SDR brightness and outperforms both the Q9FN and the Q8FN, but still falls behind last year's Sonys X930E and Z9D. Edge lighting is more efficient than full array used in both the Q9FN and the Q8FN. We assume that this extra power budget is what makes the Q7FN brighter.

The high brightness values on the 2% and 10% windows will make small highlights stand out in dark scenes.

The great performance in this category makes it a great candidate for anyone looking for a TV for a bright room.

The black uniformity of the Q7FN is remarkable and certainly a major improvement over last year's Q7F. There is very little clouding around the test cross that is hardly noticeable.

The standard deviation is higher when local dimming is set to high and clouding is a little more obvious. This happens because of the way local dimming works. We must set the backlight to higher levels to reach a luminance of 100 at the center of the test cross. This causes more blooming in general, and explains the higher measurement than the native black uniformity.

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.

The color management system wasn't very effective at correcting color accuracy. Most of the corrections were done on the white balance, which in turn corrected some of the color accuracy. After calibration, the gamma follows our target 2.2 almost perfectly, and white balance is almost perfect.

Calibration had to be done with a 100% window, as the local dimming feature was interfering with our calibration.

For most people, setting the gamma to +2 with the 'warm 2' color temperature will be good enough.

Samsung Q7FN EOTF

The 2018 Q7F has an impressive color gamut. It covers practically the entire P3 color space, and has the best Rec 2020 coverage of any TV we have reviewed. HDR content will look very close to what the creator intended.

The color gamut is even wider than the Q8FN. This is not due to panel variance as the two are definitely not the same panel, as shown by the difference in the Q7FN and Q8FN pixel photos.

The EOTF curve follows our input stimulus nearly perfectly, and it has a slightly smoother roll off at the TV's peak brightness, so there will be less clipping in bright scenes. The PC and Game EOTFs approximately follow our input stimulus, which is good.

Pixels
Samsung Q7FN Pixels Picture

The pixel structure is quite different between the 2017 Q7F and this year's model. This is good as last year's model had some artifacts due to the strange blue sub-pixel structure. This is also a different pixel structure to the other 2018 QLEDs we've tested (Q8FN and Q9FN).

The 2018 Q7F has great motion handling. There is very little motion trail, and only a little persistence blur, most people won't notice it. It has an excellent response time, very similar to the higher end Q8FN although not as good as last year's model. The TV is not flicker-free, and the backlight changes depending on interpolation settings. Like other Samsung TVs we have reviewed recently, it is inconsistent at removing judder when watching 24p content played from a 60i source.

The Samsung Q7FN uses PWM to dim the backlight. There is visible flicker at all backlight settings. At low backlight settings the flicker becomes more apparent.

The 2018 model has a 240Hz flicker, which is a marked improvement over the 120Hz backlight on the 2017 version. People sensitive to flicker could consider the Q8FN instead which has a much less noticeable 480Hz flicker.

The Samsung Q7 2018 has excellent low input lag. Like the other 2018 QLEDs, it can interpolate low frame rate games up to either 60Hz or 120Hz. Unlike other TVs, it is able to interpolate without adding significant input lag. It supports 1440p @ 120 Hz, great for Xbox One S / X gaming. It supports chroma 4:4:4 for use as a PC monitor, but colors are washed out in 4:4:4 with a 1440p @ 120Hz resolution, like all Samsung TVs we have tested. PC Mode doesn't work with a 24Hz input signal but this is an uncommon setup and shouldn't be an issue for most people.

1440p @ 120 Hz: 10.0 ms

Excellent low input lag across all resolutions and refresh rates, as long as Game Mode is activated. Outside of Game Mode, input lag is high, but not terrible.

High-end 2018 Samsung TVs like the Q7FN and NU8000 can interpolate lower frame rate games up to 60 Hz or 120Hz without adding much input lag. When interpolating up to 60Hz (With the 'Judder' slider set to 10 and the 'Blur' slider at 0, input lag is 21.7 ms, which is still very low. When interpolating up to 120 Hz (with both sliders at 10), input lag is 27.5 ms.

The Q7FN supports the new Auto Low Latency Mode. When connected to a supported device (like the Xbox One or PS4), the TV will automatically switch to game mode when a game is detected.

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 24.8 ms.

The 2018 Q7F QLED TV supports most common resolutions without issue.

For use as a PC monitor, it is necessary to enable HDMI UHD Color from the External Device Manager for the port used, and the input label must be set to PC. This is required for the TV to support chroma 4:4:4.

In 1440p @ 120 Hz, chroma 4:4:4 is displayed but the colors are not displayed properly, same as the Q8FN.

The frequency response is decent. LFE (low-frequency extension) is at 70Hz, which is above-average. This means this TV won't produce any low rumbling sounds or thumps, but will have a decent punch to its bass. The response above the TV's LFE is quite well-balanced, suggesting clear and intelligible dialogs. However, since the TV doesn't have a room correction system, it wasn't able to remove the modes of our test room around 200Hz. Additionally, this TV gets moderately loud, but may not be loud enough for large and noisy environments.

Differences between Sizes and Variants

We tested the 55" (QN55Q7FN) version AA01. For the most part, we expect our review to be valid for the 65" version (QN65Q7FN) and 75" version (QN75Q7FN).

The warehouse variant of the 2018 Q7F is known as the Q75FN. The stand is black instead of chrome, and depending on the specific warehouse model it might have a simpler remote. We don't expect any other differences and our review should still be valid.

If someone comes across a different type of panel or if their Samsung Q7FN doesn't correspond to our review, let us know and we will update the review.

Bottom right: Samsung NU8000 (UN55NU8000 ).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Samsung Q7FN is a powerful, versatile TV with great performance for pretty much everyone, but at a very premium price. While it is a great TV, there are some better alternatives depending on your needs.

LG C8
55" 65" 77"

The LG C8 is one of the newest OLED TVs on the market, and it produces exceptional pictures. This OLED TV is able to produce perfect blacks and an infinite contrast ratio. It has a much wider viewing angle and excellent uniformity, so it is a great choice for sports fans. The main marketing point to the QLED line is the impressive color reproduction, and the Q7FN is no slouch. It has a much wider color gamut than the C8 and is more effective at producing deep, saturated colors. If you want the best dark room viewing, get the C8. If dark room viewing isn't as important to you, the Q7FN is the better choice.

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

The X900F is Sony's current flagship LED TV, recently updated for 2018. The 900F produces slightly better picture quality, thanks to the full array local dimming feature. The Q7 is a bit brighter for SDR content while the X900F is brighter for HDR content. The Q7FN has a much wider color gamut and much better color volume. If you want the best colors possible with HDR content, go with the Q7FN; if not, then the X900F is a better choice.

Samsung Q8FN
55" 65" 75"

The Q8FN is the big brother to the Q7FN, and has also been updated for 2018. The Q8FN lacks the OneConnect box, so all of the connections are out of the side. It is slightly more versatile thanks to the Full Array Local Dimming feature, so it is able to produce deeper blacks, great for dark room viewing. The Q7 is brighter and has better uniformity, great for bright room viewing. They are both great TVs, but the Q7FN can do more for less.

Samsung Q7F
55" 65" 75"

The Q7F is a low-end QLED released in 2017, and is the predecessor to the Q7FN. While the Q7F is a good TV with some advanced features, the 2018 model is superior in almost every way. The Q7FN has better overall picture quality, especially since it is significantly brighter. They both handle motion well, although the Q7FN has less visible flicker. The Q7FN is the better buy.

Great for watching sports in a bright room. It has excellent reflection handling and an excellent response time. The viewing angle isn't very wide, which could be problematic for some people for game day parties. It has great gray uniformity, with little dirty screen effect.
8.8Video Games
Show Help
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 TV for playing console or PC games. It has excellent low input lag across all supported resolutions and can interpolate low frame rate games without adding much lag. Motion handling is great, and fast-moving objects look clear, but the viewing angle is limited so split-screen couch co-op isn't the best.
7.8HDR 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.
Good TV for watching movies in HDR in a dark room. It has an excellent native contrast ratio, but the local dimming feature is limited and can't boost the black levels. It has the widest color gamut we have measured, and excellent color volume, so movies look closest to what the content creator intended. Bright highlights in some scenes are able to get very bright.
8.5HDR 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.
Great TV for gaming in HDR on a PS4 or Xbox One S or X. It has excepetionally low input lag, and a fast response time, so games respond quickly to every button press and motion looks smooth. Games look amazing thanks to the wide color gamut. It doesn't have a very effective local dimming feature so late night gaming isn't as great as it could be.
8.3PC Monitor
Show Help
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 TV for use as a PC Monitor. The Samsung Q7 supports chroma 4:4:4 so text looks as sharp as it can. It has a limited viewing angle, so it is best when seating directly in front, but if too close, the edges can appear non-uniform. Motion handling and response time are great, so there isn't much mouse lag.

Is there a big difference between the Q7FN and the Q6FN besides the "black elite"?

I'm looking to upgrade from a Panasonic ST60 and want 75 inches or larger. The X900F is my top pick but it's too expensive, so I'm thinking I will either wait for the Vizio P 75 and see how it performs or just buy a Q6FN if it performs close enough to the Q7FN. If I wasn't so impatient I'd wait until the 2018 sets start going on sale and buy a X900F. Thanks!

While we haven't reviewed the Q6FN yet, there are a few differences on paper, but nothing major. The biggest difference is the OneConnect box on the Q7, the Q6 has all of the connections on the back. The Q7FN had a very good contrast ratio, but we're not sure what part of that is considered due to the 'Black Elite' feature.

Coming from a plasma TV, there are a few things you will likely notice:

  1. Plasma TVs have much wider viewing angles.
  2. Newer TVs are much brighter.
  3. Motion is very different between plasma and new LED TVs. One is not necessarily better than the other, it is just different.
The Q6FN will likely always be cheaper than the other two and there shouldn't be a significant difference.

Hi, I really like the TV stand you guys used in the review, do you mind telling me where I can buy it? Thank you very much!!!

It's the LACK TV unit from IKEA, but it doesn't seem to be available in that color any more.

I am trying to decide on a 75" TV. I am between the Samsung Q7FN and the 2018 Vizio P Series. Which one would you recommend?

Unfortunately we haven't reviewed the Vizio P Series 2018 yet, and the 75" isn't available yet. Assuming the 2018 is similar to the 2017, the Q7FN is better for most uses. The Vizio has a better local dimming feature, so dark room viewing is better, but it also has higher input lag, especially when it is used as a PC monitor or for HDR gaming. It is possible that these have changed in the 2018 model though. We will probably review the P series in the coming months.

I currently have a 65" KS8000, is this a worthy upgrade or would I not be improving much over the KS8 series?
It is important to note that the KS8000 and the Q7FN were not tested on the same testbench, so the scores are not directly comparable. The KS8000 is very similar in performance to the Q7FN, but the Q7FN can reach higher SDR and HDR Peak Brightness. The KS8000 has better native contrast than the Q7FN, however the Q7FN has better gray uniformity. The color accuracy is better on the KS8000, but the Samsung Q7FN can display a wider color gamut. Overall, the Q7FN is slightly better than the KS8000, but the cost of the upgrade would not be worth it.

In your review, you state that the input lag for game mode is much lower. I plan on using a TV in PC mode, and am wondering if the input lag is higher, lower, or the same for game mode and PC mode. On my current Samsung TV (MU6500) you cannot turn on game mode while in PC mode. Thanks for all the amazing content, seriously you guys are lifesavers.
The input lag for the Q7FN is the same in PC and Game modes. PC mode HDR is slightly higher, but still very good. In our reviews the PC mode input lag is measured with the 4:4:4 tests (4k @ 60Hz @ 4:4:4, 4k @ 60Hz @ 4:4:4 + 8 bit HDR). Glad you enjoy the site!

Do you expect a software fix for the horrible local dimming performance you recorded? And did you report that to Samsung?
The performance we are seeing is was somewhat expected. It is similar to other "entry" level premium TVs from Samsung, including last year's Q7 and Q8C, and this year's NU8000. We don't expect this will be significantly improved through firmware updates, although some improvement is possible.

Wow. I'm impressed, and think you all sold me on this TV. I assumed I would go with the C8, or Q8FN, as I can't go larger than 55". However, my concerns with uniformity, local dimming issues, and issues with real world nit performance, regarding FALDs, the Q7FN looks like the best bang for the buck in the Q range.

Especially when considering I watch in a bright room, and have ambient lighting on at night. It makes sense why Samsung continues to offer edge-lit models, and why the Sony 930E is so popular. I love the OLEDs, however for my conditions, and viewing habits, its not the best option.

Truly appreciate what you all are doing, and keep up the great work! Best Wishes!

Thanks for the feedback! We agree, the Q7FN is truly a great TV, and based on what you've told us it probably is the best one for you.

Hello, I have the curved version of this TV, on my PC I can't get it to display 1440p at 120hz like you guys say it can. How did you guys get it to do that?
The Q7FN doesn't have 1440p in the EDID, so most computers won't detect it as supporting a 1440p resolution. You have to add it as a custom resolution. The procedure to do this depends on your graphics card.

Great job on the excellent reviews! I need to know what the input lag at 4k with BFI on in game mode is, with blur and judder at 0. My Leo Bodnar tool is showing 32 ms but I can’t check at native 4k, thank you!
29.5 ms is the 4k @ 60 Hz + BFI input lag in game mode with both sliders at zero. Also game mode can still be enabled when the input's icon is set to PC; the input lag doesn't change, but all the Game Motion Plus options can be used, including BFI.

How is the light bleed from the LEDs during dark room viewing?
The Q7FN offered great black uniformity, with very minimal clouding in our most recent tests. This model performs very well in dark conditions and should not show any noticeable light bleeding when used at a proper brightness. The Q7FN can get very bright and has poor local dimming, so there will be noticeable vertical blooming at high backlight values, especially in a dark room.

Need your urgent help on making decision on buying TV before deal expires!
What is your recommendation below, buying from Costco, with both TV having 4 extended years Manufacturer Warranty.

This is for a very bright living room, family of 4 with not everyone having a front facing seat. I am particularly concerned if the curved model will distort reflections during the day and if people sitting in corner would have trouble watching it from slight angle.
The MU8000 is better than the MU8500, especially given your room requirements. With the MU8500 the curved screen does exactly what you were concerned about; depending on where you are sitting the curve will either eliminate glare or focus it to be more distracting.

I have the X900E on hold since I am building a new home. I am wanting to switch to this Samsung Q7FN because of the great review and ambient mode. The only thing that’s holding me back is the bad local dimming. Should I get the Samsung or stay with the X900E?
The Samsung Q7FN is a better choice if you are a competitive gamer or if you want the most vivid colors, but generally it isn't worth the price difference over the X900E.

Hello, great reviews by the way. I'm still slightly confused as to the local dimming on this TV gets such poor ratings but yet it can still produce deep blacks. I'm narrowing down my choices to either the Sony x900f, one of the new Samsung Quantum's or perhaps the new Vizio Quantum once it's released this summer. It seems like you recommend the Q7fn over the Sony x900f for people who may be interested in richer colors. My question is would the blacks still look better on the Samsung Quantum's vs the x900F with superior local dimming? I would be using the computer as a PC monitor, gaming, watching sports and movies. I do like really rich colors but I also want solid blacks and good response times as well. I would be willing to pay for either the q8fn, q7fn, Sony x900e. I think the Vizio will only be available in 65 inches which may be too big at this time anyways. I wouldn't mind an OLED but using it as a PC monitor, I'm worried about burn-in. Which would you recommend for my uses, the x900f, q8 or q7?

Thank you for contacting us.

The reason local diming gets really poor ratings is due to its ineffective algorithm. The TV can produce great blacks because it has a very high contrast ratio.

The absolute best of the three in terms of performance is the Samsung Q8FN, so if budget is not an issue go for it. However, the differences in performance both with the Sony and with the Q7FN are small.

Comparing the Q7FN with the X900F you will see that the Q7FN has a much wider color gamut and better color volume, hence the richer colors, whereas the Sony has deeper blacks due to better local dimming. So if best possible colors and HDR is what you seek, go with the Q7FN; if not, then the X900F is a better value for money

Does the Q7FN exibit the same tone mapping issues (overbrighting) that the Q9FN has?
It does a bit, as shown in this EOTF plot measured with a 1000 cd/m² HDR infoframe, but reducing the contrast to 40 mostly fixes it, as shown in this EOTF. Note that the root of the problem with the Q9FN was that it treated different HDR infoframes differently, and the same is true of the Q7FN: the EOTF when a 10,000 cd/m² infoframe is sent follows the target PQ closer than the EOTF when a 1000 cd/m² infoframe is sent, so not all content will suffer from the same overbrightening.

Is the viewing angle score on this tv accurate? The score is comparable to my old tv (color shift 20, brightness 30, black level 21) yet significantly worse in real world use. I’m extremely disappointed in how quickly the colors and blacks wash out using the exact same seating arrangement used for my previous tv in my living room. I didn’t discover the problem until I invited friends over to watch a movie and most scenes ranged from awful to unwatchable when just slightly off to the side. I am now past the stores return policy, so I’m now left with immense buyers regret after spending $1600. Please re-review your viewing angle score so that other potential buyers are properly informed!
Vertically Aligned (VA) panels have better contrast performance at the cost of bad viewing angle. It's a compromise the manufacturer has to make when choosing parts. The Q7FN received a score of 4.3 on the viewing angle score which puts it at the bottom third of our viewing angle chart. Without knowing your old TV model it's difficult for us to compare but we do mention in the review that the "viewing angle is disappointing but typical for a VA panel."
