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.

Resolution : 4k

The Samsung NU8000 is a versatile 4k LED TV with good picture quality and HDR support. It also has great motion handling, as only a short trail follows fast moving objects and the TV can flicker to clear up blur. The smart features also work well and the platform is intuitive. The TV includes the Bixby assistant for voice control. Unfortunately, the picture quality degrades when viewed at an angle and vertical blooming is visible in a completely dark room.

See our recommendations for the best 4k TV.

Pros
  • Great motion handling
  • Low input lag
  • Great SDR peak brightness
Cons
  • Colors appear washed out at an angle

Samsung NU8000 Design Picture
Curved : No

The design of the Samsung NU8000 is excellent. Compared to the MU8000, the new stand feels very solid and has a slightly smaller footprint, although if you were planning on using a soundbar in front of the TV, you might have to make some concessions. There are new cable management guides cut into the back. The TV does not include the mini OneConnect box, all of the connections are towards the side of the TV.

Stand
Samsung NU8000 Stand Picture

The stand is very different than the ones on the two previous models (the MU8000 and KS8000). It is very similar to the stand found on the JU7100. The TV is very stable and there is very little wobble.

Footprint of the 55" TV stand: 12.5" x 31.4".

Back
Samsung NU8000 Back Picture
Wall Mount : Vesa 200x200

The back of the TV has a textured finish very similar to last year's MU8000. It has new tracks for cable management that are cut the entire width of the back of the TV. The VESA wall mount is 200x200 instead of the 400x400 found on most of last year's models .

Borders
Samsung NU8000 Borders Picture
Borders : 0.35" (0.9 cm)

The NU8000 has slightly larger borders than last year's MU8000. The finish of the main bezel has changed from silver to black.

Thickness
Samsung NU8000 Thickness Picture
Max Thickness : 2.28" (5.8 cm)

The TV is quite thin when viewed from the side, although it is slightly thicker than last year's MU8000.

When wall mounted, the TV doesn't stick out much which is good. The lack of the OneConnect mini means you will have more work if you need to change the connections, but you don't have to worry about where to place the box.

The TV stays fairly cool even after extended use, only getting a little warm to the touch along the bottom edge where the edge light LEDs are located. The NU8000 has vents along the bottom edge so if you are planning on wall mounting the TV, you shouldn't have any issues with heat dissipation.

7.0 Build Quality
Samsung NU8000 Build quality picture

The overall build quality is average, nearly identical to the MU8000. It is almost entirely made of plastic but feels solid. We haven't experienced any quality issues.

The Samsung NU8000 has great picture quality. The high native contrast ratio produces deep black scenes and the TV is well suited for a dark room. Performance is also good in a bright room, although there are some issues with reflections. This TV can get bright enough for an enjoyable movie or TV experience, whether you are watching SDR or HDR content.

The TV uses a VA panel with a poor viewing angle. The gray uniformity is good with minimum dirty screen effect and so is a good choice for watching sports. It handles upscaling lower resolution content well. White balance and gamma are very good post calibration, although we are unable to correct color accuracy. It has a wide color gamut, although there are some issues displaying greens and any deep, dark colors.

Excellent native contrast ratio on the Samsung NU8000, approximately 15% better than the MU8000. This high contrast ratio allows the TV to produce deep black scenes, especially when viewing in a dark room.

The local dimming feature has very little impact on the contrast ratio. This is to be expected as the local dimming on this edge-lit TV is not very effective at making blacks deeper.

The local dimming on the NU8000 is bad. It dims the screen less than the MU8000, but focuses the dimming on moving highlights as it should. This helps reduce the amount of visible blooming and the black levels appear raised.

Poor viewing angle. Colors and brightness shift if you are even slightly off center.

Black uniformity is very good on the NU8000. No clouding can be seen with or without local dimming. Standard deviation is much better than last year's MU8000, and this year's X900F, which results in uniform dark scenes without distracting areas.

Like the MU8000, it is impossible to completely disable local dimming on this TV. As such, it is impossible to determine the true native black uniformity performance of this TV. We ran our test with the local dimming feature set to 'Low' (the lowest setting). The test for black uniformity with local dimming was taken with local dimming set to 'High'.

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.

Good color accuracy out of the box, but follows our target of 6500K and 2.2 gamma much worse than last year's MU8000. White balance has too much red/green and gamma is too high across the entire curve at 2.42. The color temperature is cold at 6032K giving colors more of a yellow tint.

Samsung NU8000 EOTF

Good color gamut on the Samsung NU8000, slightly better than the MU8000. Colors in HDR will be fairly accurate, although the TV has difficulty displaying deep greens. Very similar results to the Sony X900E.

The 'Movie' picture mode's HDR EOTF follows the target PQ curve very well, up until it rolls off into its max brightness. 'Game' and 'PC' modes also have fairly accurate EOTFs. In 'PC' mode the 'Dynamic' picture mode has the best HDR EOTF, because 'Standard' mode has a bug where it sometimes gets stuck in a dim state.

Update 05/02/2018: The color gamut was erroneously measured at a 50% stimulus. It has been remeasured at 75% stimulus to be in line with our other TVs. The results remain almost identical.

Motion looks good on the Samsung NU8000. It has very fast response time, 120 fps motion interpolation, optional 60 Hz black frame insertion, and can remove 24p movie judder from most sources. Unfortunately, its backlight always flickers at 240 Hz, which introduces unwanted duplications during motion, and its fast response time can introduce stutter sometimes during low frame rate content, like wide panning shots in movies.

The TV dims its backlight by using PWM flicker at 240 Hz. This flicker is unfortunately present at all brightness levels but is less severe at high brightness.

The Samsung 55NU8000 has a 120 Hz panel, and can interpolate lower frame rate content up to 120 fps. This makes motion much smoother, but can look strange to some people (the so-called 'soap opera effect'), and sometimes adds unwanted artifacts during fast motion. Interpolation is activated by setting 'Auto Motion Plus' to 'Custom'; increase the 'Judder Reduction' slider to interpolate low frame rate content, and increase the 'Blur Reduction' slider to interpolate 60 fps content.

Game mode now also has motion interpolation, 'Game Motion Plus', which doesn't look as good as 'Auto Motion Plus' but adds much less input lag, as explained in the Input Lag box.

The NU8000 does not support FreeSync from our Radeon RX 580 GPU. We tried various combinations of game mode, PC mode, input refresh rates, etc., and 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.

Excellent low input lag, good enough for even competitive console gaming. This input lag is lower than last year's Samsung TVs like the MU8000, and lower than many current Sony TVs like the X900F, but is slightly worse than many TCL TVs like the P607.

The NU8000 has a new 'Game Motion Plus' feature, which adds motion interpolation (soap opera effect) without adding too much input lag; this feature is useful when gaming on older consoles that can only output 30 fps, or for games that have frequent framerate dips. The 'Judder Reduction' slider interpolates content up to 60 fps, while the 'Blur Reduction' slider interpolates up to 120 fps. When 'Blur Reduction' is used the input lag for 4k increases from 23.8 ms to 29.3 ms, but this increase shouldn't be noticeable during gaming.

Update 04/24/2018: 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 9.7 ms, down from 24.8 ms.

Most common resolutions are supported. 4k @ 60 Hz @ 4:4:4 or 4:2:2 color is only supported when 'HDMI UHD Color' is enabled (aka HDMI 2.0 full bandwidth). New this year is 1080p @ 120 Hz @ 4:4:4 support, which is useful when using the TV as a PC monitor. 1440p @ 120 Hz is also supported, but 4:4:4 color isn't displayed properly. Oddly enough, 1440p @ 60 Hz isn't supported, not even when using a custom resolution from a PC.

4:4:4 chroma subsampling is only shown properly when the input's icon is set to 'PC' (aka PC mode). This unfortunately isn't possible for some input refresh rates such as 24 Hz; in these cases the icon changes to PC as normal but PC mode isn't applied, as evidenced by the improper 4:4:4 color resolution and some settings not being greyed out as they should be.

Score components:

The sound quality of the Samsung NU8000 is decent. This TV gets fairly loud and has a bass extension that is better than most TVs. Overall they have a well-balanced sound, but they don't have a self-calibrating system for a more even bass response and could produce some compression and pumping artifact under maximum load. For a better sound reproduction, getting a dedicated soundbar is recommended.

The frequency response of the NU8000 is decent, and very similar to the 2017 model the MU8000. The LFE (low-frequency extension) is at 67Hz, which is good and lower than what most TVs are able to reach. This means that the TV should be able to produce a decent amount of bass and punch. However, due to the lack of a self-calibrating system, it wasn't able to remove the room buildup around 200Hz. The response in the mid and treble ranges are quite even and flat, ensuring a neutral sound reproduction. Additionally, the maximum loudness of the TV is above-average, but they may produce some pumping and compression artifacts under maximum load.

The harmonic distortion performance is about average. The overall amount of THD is rather elevated, but on there doesn't seem to be a dramatic rise in THD under maximum load. However, the sharp peaks around 1KHz and 2KHz, could the make the sound of those frequencies a bit harsh and brittle.

Samsung's SmartThings app can be used as the TV's remote, but it doesn't have as many features as the old SmartView app, which unfortunately doesn't work with this TV. On Samsung phones the SmartThings app has a few additional features, such as sharing the TV's screen with the phone, as shown in this screenshot. Although there is a microphone button in the app, and pressing it brings up the Bixby voice icon on the TV, we couldn't make the TV receive audio from any of the three smartphones we tried.

Update 04/27/2018: 'Launches Apps and Inputs' has been corrected to 'No', because the app's 'Source' button only acts like the 'Source' button on many remotes, and does not launch inputs directly.

Update 06/04/2018: We have retested the SmartThings remote app with a Moto E4 and the voice control now works. The remote app can perform the same voice commands as the smart remote. The score has been updated.

Bottom right: Sony X900F (XBR55X900F).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Samsung NU8000 is a very good 4k TV without major flaws, but for different usages, there may be a better choice - especially considering the price premium of this 2018 model over comparable 2017 TVs. See some of our recommendations below for comparisons.

Samsung MU8000
49" 55" 65" 75" 82"

The Samsung MU8000 is the predecessor to the NU8000. It has good picture quality, with a very similar VA panel but can't produce quite as saturated colors for HDR and doesn't get as bright. It also lacks a few gaming features found on the newer model such as 120Hz input support and interpolation with very low input lag. Overall, the newer NU8000 is a better TV, but mostly for gaming or HDR. For other uses, the difference between the two is minor, get the cheaper of the two.

Sony X900E
49" 55" 65" 75"

The Sony X900E is a 4k TV available from 49" to 75" with great picture quality from directly in front, but like the NU8000, it degrades when viewed at an angle. It is great in both dark and bright rooms since the local dimming works well to limit blooming in dark scenes and the TV can get bright to overcome reflections in a bright room. It isn't quite as good for gaming as the NU8000 as it lacks some gaming specific features, like 60Hz flicker to clear up fast motion and motion interpolation with very low input lag. Overall, the X900E is a better TV and a better choice for most people.

Samsung MU6300
40" 43" 50" 55" 65" 75"

The Samsung MU6300 is a mid-range TV with better than average performance. It has decent picture quality, but this is limited by the lack of more advanced features such as a wide color gamut, local dimming, or the ability to produce bright highlights. It has a fast response time so fast motion remains clear, but it has limited options to adjust the flicker to clear up motion further and some small judder is present when watching movies. For watching cable TV, SDR movies or for gamers who don't care about HDR, the MU6300 is a great choice

LG SJ8500
55" 65"

The LG SJ8500 is an IPS TV available in 55" and 65". It has decent picture quality, but the image remains accurate even when viewed at an angle so is best suited for those with wide seating. It also has poor dark scene performance due to the low native contrast ratio, but this isn't noticeable in a bright room. For a bright room with wide seating, the LG SJ8500 is a better choice, but for watching TV from directly in front in a dark room, there are better and more affordable options.

Good TV for sports fans. Motion handling is great, so fast-moving objects appear clear. Picture quality is good from directly in front but degrades when viewed at an angle. The TV can get bright to overcome glare in a bright room, and anti-reflection coating is good at diffusing direct lights on the screen.

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 gamers. Picture quality is good when viewed from directly in front. Motion handling is great, so fast-moving objects remain clear. The Samsung NU8000 can also flicker the image to clear up fast motion, and input lag is very low which is excellent.
7.7HDR Movies

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 for watching HDR movies in a dark room. Picture quality is good and can produce more bright and vivid HDR highlights due to wide color gamut and high peak brightness. The TV can play most content without judder, which is great. Unfortunately, the local dimming doesn't work as well as some other TVs.
8.3HDR Gaming

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 HDR gaming on an Xbox One S or PS4 Pro. Picture quality is good, and motion handling is great due to the fast response time. The TV supports HDR features like a wide color gamut. The Samsung NU8000 also has a motion interpolation feature which works in game mode to produce smooth images with very little input lag which is great.
8.2PC Monitor

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 PC use. The TV supports chroma 4:4:4 for clear text across all backgrounds. Picture quality is good but degrades when viewed at an angle so the sides of the screen can appear non-uniform from up close. Motion handling is great, and the TV feels responsive thanks to the very low input lag.

I know that every new TV is marketed as "4K 120Hz", but I haven't seen any that can actually output 4K at 120Hz. Do you know when we might see TVs that can actually do this?
A 120Hz 4K signal requires greater bandwidth than current HDMI 2.0 ports and cables can provide, so it is currently not possible. HDMI 2.1 has been announced with full support for 4K @ 120Hz and even higher resolutions, but the standard has not been finalized yet. While we might see some devices with support for HDMI 2.1 in the second half of 2018, chances are we won't see full support until 2019.

Good review, but kind of predictable considering it’s an edge lit LED. When are you reviewing the new Q9 that Samsung updated with local dimming for this year?
Hi and thanks for contacting us. We should review the new Samsung Q9FN in the coming weeks.

The NU8000 has an 8-bit panel, but you list it as having a 10-bit panel.
The NU8000 has an 8-bit panel, but it uses FRC (dithering) to approximate the 10-bit color depths. Since it accepts a native 10-bit signal, and it is next to impossible to differentiate between 8-bit with FRC and native 10-bit we list it as a 10-bit. The color depth listing has no impact on the final score, the only thing that matters for this result is how well the TV displays the test gradient.

Your review mentioned the TV accepts a 3D signal. Surely this must be a typo and the TV is not 3D, right?
This was an error on the review, thank you for pointing it out.

There appears to be some differences between Samsung's claims for the NU8000 and your test results. Samsung claims these sets will support "AMD Freesync", but you could not verify that. Samsung claims that the variable refresh rate of the XBOX ONE S and ONE X will be supported, but you offered no opinion on this. In your opinion, how good is the new "game mode" feature on the NU8000 and above models?

The problem is most of Samsung's new features are waiting on updates, either to the TV itself or to game consoles. The variable refresh rate feature of the Xbox One S and X has not yet been rolled out; we will retest the NU8000 and some other Samsung TVs when it's released. Samsung's new 'Game Mode Auto' feature is waiting on console makers to implement the signalling on their consoles, to tell the TV 'I'm playing a game now' so the TV knows when to switch to Game Mode.

About FreeSync, the only means we have of testing it is with our Radeon RX 580 GPU, and it was not detected as supported. So far only the Samsung QLEDs have been rumored to support Freesync; we will be testing one soon to confirm this.

Aside from all this, the only new thing Samsung has added to Game Mode is their 'Game Motion Plus' feature, which adds motion interpolation (soap opera effect) while only raising the input lag by 6-12 ms. This is useful for older 30 fps games, or games that have frequent frame rate dips; you can read more about it in the input lag section.

Do you guys test 1080p gaming from PC or just console? I'm looking for a TV to use as a 4K PC monitor, but play games at 1080p (due to the performance impact when gaming @ 4k). Is this a good TV for that?

We don't test gaming specifically, but a few of our tests are designed with gaming in mind. Our input lag tests are done in and out of 'Game Mode' and we test various resolutions to make sure the TV supports most common input resolutions. The input lag on the Samsung NU8000 is excellent, and we tested it at 4k and at 1080p and they are very similar. This is a good TV for PC Gaming, but keep in mind the limited viewing angle, you'll want to be far enough from the screen that the picture doesn't degrade towards the edges.

Excellent review as always. Samsung's line-up last year was inferior to the previous year's KS8000 in this price range. How would you say that this TV compares to the KS8000? Thanks.
The KS8000 was tested on an old Test Bench version, as such the two are not directly comparable. That being said, the KS8000 has brighter highlights, but real scene brightness is similar. The NU8000 has better smart features and lower input lag.

Am I reading this right, the TV supports 1080p@120Hz? I was hoping to see HDMI 2.1 with eARC support. Is it possible the TV will receive eARC support via firmware update? I wish Samsung made 40" TVs with similar features. I look forward to see the 2018 versions of the MU6300 and MU7000, I read they might have 40" models.

The NU8000 fully supports 1080p and 1440p @ 120 Hz. We don't expect to see HDMI 2.1 on any TV until 2019, and while it is possible that the NU8000 will receive eARC support via a firmware update, we don't know if Samsung will.

40" TVs are not updated as frequently as the more mainstream sizes, but there are some great sets out there. Samsung has yet to announce any new TVs for 2018 in these sizes. We recently updated our recommendations for 40-42-43" TVs here.

I've decided on either the X900F or the NU8000. I watch a lot of movies, fast sports, and play games. I know FALD is better than edge lit. Low input lag is also very important to me. My question is when it comes to picture quality and motion handling is the X900F worth $500 more than the NU8000 or is the difference slight? Thanks for your great reviews.

Thank you for your kind words.

Between the X900F and the NU8000, go for the NU8000 as the price difference is not worth it. You should also consider the X900E which is similar in price to the NU8000. It does not have as low an input lag as the NU8000, but it is a better TV overall.

1
For a set where gaming is the predominant focus, would you recommend the NU8000 or the X900F?
If it is for 4k gaming exclusively, go with the Sony X900F since the input lag is in the same ballpark as the Samsung NU8000 and you get a much better local dimming and also a better motion. Go with the Samsung NU8000 if you intend to game at a 1080p resolution though, as it has a much better input lag than the Sony at a 1080p resolution (18.1 ms versus 40.9 ms for the Sony X900F).

So it seems the motion/stutter/flicker is on the MU8000 better? And is there more banding on the NU or is it the same like the MU?
Motion wise they trade blows: the significant differences are the less noticeable flicker of the NU8000 (240 Hz vs 120 Hz), and the better 24p judder removal over 60i of the MU8000. Overall their motion is fairly similar. The NU8000 though has noticeably less banding than the MU8000 in our gradient test, which is better for HDR content.

I have a suggestion regarding the "Ads" rating. Instead of having it 0 or 10, it should be Pass or Fail (which the 0 or 10 basically is.) The way that it is now is confusing; I was reading the review and got down to where it said 0 Ads and I thought "Wow, that's an incredible change, Samsung is notorious for having unremovable ads." Then I read the section and realized that it was a 0 score instead of it having 0 ads. It would be much less confusing if it were PASS/FAIL, green checkmark or red x, etc.
Thank you for the excellent suggestion! We agree that the tone of the box doesn't match the score, so I've changed the box name to 'Ad-Free' (10 for Ad-Free is excellent - no ads). Let me know if you think this is a good solution.

According to Samsung this TV uses an 8 bit panel (at least in NA). The MU8000 used a 10 bit panel. The NU still has a wider color gamut?
TVs with 8 bit panels can use dithering techniques like FRC in order to show 10 bit colors. If a TV with an 8 bit panel implements dithering well then it's nearly indistinguishable from a TV with a 10 bit panel. We don't distinguish between TVs with 10 bit panels and TVs with 8 bit + dithering, we only judge the TV by its measured performance. We haven't confirmed whether the MU8000 or NU8000 use 8 bit or 10 bit panels, but we suspect most HDR TVs we test use 8 bit + dithering. Also 8 bit vs 10 bit doesn't affect the color gamut, it only affects its color gradient perfomance / banding, as seen in our gradient test.

Looks like the NU8000 has 6.0 score for the image flickering. I am kind of sensitive to the backlight flickering. Do you think the NU8000 backlight flickering is ok for me?

The backlight of the NU8000 flickers at a fairly high refresh rate (240 Hz), which should be invisible to most people, but it does cause some unwanted duplications. If you are particularly sensitive to backlight flicker, you may want to consider a relatively flicker-free TV like the Sony X900F.

How does this compare to the KS8000 from 2016?
The KS8000 hasn't been tested since Test Bench version 1.0, so the scores are not directly comparable as there were things we didn't test for back then. From what we did test, the two are very similar. The KS8000 has a better native contrast ratio and small highlights in some scenes are brighter, but the overall experience should be similar.

I am interested in NU8000 and am really worried about clouding, though you say there is none. On the pictures for Black Uniformity it is pretty apparent. Is this an error?

Thank you for contacting us!

The unit we tested scored very well in Black Uniformity. Remember though, that results can vary a lot from unit to unit, and personal sensitivity to clouding/black uniformity issues. Keep in mind that you are seeing a picture of picture and the calibration/setup of your monitor might be another factor.

You mention that the new "Game Motion Plus" feature is good for clearing up games with poor frame rate. While I understand and have seen the benefit of using Motion Plus on my KS8000 for bringing stable 30FPS games up to 60FPS, I've found that games with unstable framerate (frequently falling from 30FPS, or hovering around 45FPS) are equally as stuttery as they are without any Motion Plus enabled. It does not seem to smooth them up at all. Does Game Motion Plus work differently? Have you tested any games with an unstable framerate to see if it smooths them over? Also, is the artifacting of Game Motion Plus more or less severe than regular motion plus settings? I want to know if this is actually a viable option for bringing my 30FPS games up to 60/120FPS reliably, or whether it is too harsh to actually use comfortably. If it is, I might as well go for an OLED that doesn't have this feature!
'Game Motion Plus' uses a much simpler algorithm than 'Auto Motion Plus'; this simpler algorithm adds much less input lag (~6-12 ms, vs ~50 ms) and is faster to react to changing motion patterns, at the cost of not looking as smooth as 'Auto Motion Plus'. When the framerate of a game fluctuates, 'Game Motion Plus' can react quickly to this change, so it should look smoother than 'Auto Motion Plus' in this case. We tried it with Shadow Warrior 2 on PC with the framerate varying from 40-55 fps, and the game looked fairly smooth, though we did notice small breaks in smoothness when the framerate changed rapidly, such as when looking at a wall then turning the corner. We also barely noticed any artifacting at all, because the algorithm is far less aggressive than 'Auto Motion Plus'.

I really think you need to look at the 82 inch. I purchased it and refused delivery based on your review, brightness and uniformity all were off. The picture had none of the punch of the smaller versions and I have a dark viewing area. I believe you cant lump these larger panels into the same review as the smaller variety. I am afraid to try the Sony 900E in 85 because of my experience with the 82NU8000. Have you actually verifed or tested one in any way??
We haven't tested the 82" model. We have limited resources, so we only buy one size to test (generally the most popular size, to help the most people). We bought the 55" model of the NU8000. Usually larger sizes do have more uniformity issues, but we don't know how the brightness might compare. Usually it is in the same ballpark, but it can depend on what's available.

Can you confirm if a 60 fps, 1440p signal is supported?
No, we don't yet understand why, but 1440p @ 60 Hz is not currently supported, even though 1440p @ 120Hz is.
0
Does this TV display colors correctly in 1440p HDR well for PC games?
The TV does support 1440p @ 120 Hz and can display colors correctly in 1440p, but not in chroma 4:4:4. This won't be an issue for gaming, but text will not be as sharp.

Hi, My name is Ray and I was curious. In Rtings.com professional opinion how does the KS8500 hold up against all the other Samsung TV's on the market as of late? Would the 8.1 rating change with your current methods of testing? Thanks!
The KS8500 is a very good TV, even by today's standards. It was last tested under Test Bench version 1.0, so the score can't be directly compared to TVs tested under 1.2, although it would probably score similarly to the NU8000. The KS8000 has brighter highlights in some scenes, but real scene brightness is similar. The NU8000 has more advanced smart features and lower input lag.

I want to buy the Samsung 49" NU8000, I know it is a 60HZ panel, I want to get verification that it is going to be updated with Freesync/VRR per their announcement. It sounded a little confusing to me. Before I spend 900$ I would like to know, my main use will be for Xbox One X gaming.
We can't confirm for sure if Samsung will add Freesync support to the NU8000. From their announcements it would appear to be the case, but we don't know.

I was watching a video from ABT on the NU8000 series they had just gotten and they said the panel was native 8bit but with dithering was upped to 10bit.

If this is true can you change your Gradient section to reflect the "true" specs on the panel, not the dithering effective. Thank you in advance.

The NU8000 is an 8-bit panel which uses FRC to approximate 10-bit. For our scoring, we don't differentiate between 8+FRC and 10-bit, the only thing that matters is how the gradient is displayed by the TV. A good 8-bit panel with dithering can beat a cheap 10-bit panel.

In future reviews, could you include whether the TV remote is an IR or RF remote? That would be helpful to me, as I have issues with IR remotes. Thanks
Thanks for the suggestion, we will be added a mention of this in future review texts!

I was deciding between the NU8000, mu8000, and the LG86UH9750.
I want to place this tv in a living room with high ceilings and a lot of windows (even though I can use the rollers and cover them up if needed). Which do you think is the best option for mixed usage? Mostly movies tv shows and sports sometimes.
Thanks for all you do!

Thank you for contacting us.

We have not tested the LG86SH9570 but expect to perform similarly to the LG86 SJ9500.

The NU8000 and MU8000 are very similar as you can see here.
By looking at the side by side comparison of the Samsung NU8000 vs the SJ9500, we see that for the features that matter most in your viewing environment the LG seems to be a better choice. It has wider viewing angles and handles reflections better. You might also want to tale a look at the LG SK9000 which replaced the SJ9500. It is sold at a similar price range and performs slightly better.
