The Samsung NU7100 is a decent 4k LED TV. It has decent picture quality with a good native contrast ratio but lacks more advanced features to improve the dark room performance, such as local dimming. It has extremely low input lag which is excellent for gamers but the response time is only decent so some blur is visible behind fast-moving objects. When viewed at an angle the image also loses accuracy, so the best picture is reserved for those directly in front of the TV.
Decent TV for mixed usage. The NU7100 is best suited for dark room viewing, as the screen is ineffective at overcoming glare. It has a great low input lag perfect for gaming, but poor color volume and a limited color gamut, so HDR content doesn't pop as it should. Unfortunately, the viewing angles aren't very wide.
The NU7100 is decent for watching movies. It has incredible dark room performance thanks to its amazing contrast ratio and outstanding black uniformity, but unfortunately, there's no local dimming feature to further darken any scenes. The gray uniformity is good too, so fast-moving content looks good, but sadly it can't remove judder from lower frame rate content.
Okay for watching TV shows. The NU7100 has okay reflection handling and decent peak brightness, so it performs well in average-lit rooms. Unfortunately, the viewing angles are quite poor, so the image loses accuracy when viewed from the side. On the upside, it displays 720p content, such as from a cable box, well with no obvious artifacts.
Decent TV for sports. The NU7100 55" has minor dirty screen effect, but it shouldn't be too noticeable. Decent motion handling, but some people might notice some persistence with fast motion.
Great TV for gaming, mainly due to the exceptionally low input lag. The NU7100 has a decent response time, but faster games might suffer from some motion blur.
The NU7100 is decent for watching movies in HDR. It isn't very bright and is best suited for dark room viewing. It has a limited color gamut and poor color volume so HDR content won't pop as much as the content creators intended.
The NU7100 is good for HDR gaming. It has excellent low input lag and a decent response time. It isn't very bright and has a limited color gamut and volume so HDR games don't pop as much as they should.
The NU7100 is good for use as a PC Monitor. It has exceptionally low input lag and chroma 4:4:4 is properly supported. Unfortunately, the viewing angle isn't very wide.
The stand is modern and sturdy. It's wide enough to fit a soundbar in front.
Footprint of the 55" TV stand: 37.2" x 10.3"
The borders of the NU7100 55" are simple, with a textured plastic finish, and have average thickness.
This TV is thin, similar to the NU8000. It won't stick out too much when wall-mounted, but it won't be flush to the wall either.
The build quality is okay. It feels solid even though it's almost entirely made from plastic.
The contrast on the TV is great and in-line with other Samsung TVs like the NU7300. This is good for producing deep dark scenes.
Update 06/15/2018: We've reset the TV and retested the native contrast ratio, and it's a bit higher. The calibration likely raised the black levels slightly, lowering the previously measured contrast ratio.
The NU7100 doesn't have a local dimming feature. The above video is provided for reference only.
Disappointing HDR peak brightness. It has trouble making small highlights bright, as seen in the 'HDR Peak 2% Window' test. Besides that, it remains fairly consistent across different content, although it's not very bright. This TV struggles to make highlights pop and display vivid colors. An IPS TV with similar HDR peak brightness is the LG UK6300.
The NU7100 55" has good gray uniformity. It's visibly darker around the edges of the screen but is a lot less dark in the center. This means there's no dirty screen effect, which will please most sports fans. The screen is much more uniform in darker scenes.
This TV has a poor viewing angle, but it's better than 2017's MU6300. The black levels shift dramatically when viewing even slightly off-center.
The NU7100 has excellent black uniformity, similar to the 2017 MU6300 and is one of the best among the LED TVs we've tested. There aren't any clouding issues, and black looks very uniform. As a result, dark scenes in movies look great.
The NU7100 has okay out-of-box color accuracy, although some people may notice that most colors are still inaccurate. The gamma curve doesn't follow the target well and scenes will appear brighter than they should. The color temperature is slightly warmer than the target of 6500K, so most colors will have a red/yellow tint to them.
Update 04/12/2019: This TV was incorrectly measured with Brightness +2 instead of at 0. This only has a small impact on the results (slightly dimmer dark scenes below about 30 IRE), so we don't plan to retest it.
The color accuracy post-calibration is nearly perfect. The white balance dE and color dE both significantly improved from pre-calibration, so most colors appear as they should. The gamma curve follows the target well, although some dark scenes will be brighter than normal. The color temperature is only slightly off the target, but most people won't notice any red/yellow tint.
See our recommended settings here.
This TV displays older 480p content well, without any issues or obvious artifacts.
720p input is displayed properly without any obvious scaling artifacts.
1080p content, like from a non-4k Blu-ray or game console, is displayed well and looks almost as good as native 4k content.
The NU7100 only supports a standard color gamut and is best suited for SDR content. Like the 2017 MU6500, red and green fall quite short of their HDR targets.
The 'Movie' Picture mode is the most accurate, but it doesn't follow our PQ curve. The brightness rolls off gradually as the TV gets closer to its peak brightness. The PC and Game EOTFs are very similar to 'Movie', but also don't follow our target very closely.
Disappointing color volume, mainly due to the limited color gamut of the TV. It's unable to produce deep, dark colors, and it's limited in its ability to produce bright, saturated colors like those in a sunset or bright outdoor scene.
The TV displays our test pattern well, but in real-world tests, there are small points of banding in large areas of similar color.
There's no temporary image retention on the NU7100.
We don't expect the TV to experience burn-in, as the VA panel in our long-term test appears immune.
Decent response time. In dark scenes like our 20% test slide, the 100% transition is very slow and there's some motion trail.
Most of the blur in the above photo is due to duplications caused by the backlight flicker.
Similar to the Q8FN, the flicker varies depending on settings.
This TV uses PWM to dim the backlight except when at 100%. It flickers at a high frequency (240Hz), but due to pwm at lower brightness levels, the flicker becomes more noticeable. It's an improvement over the MU6300 with its 120Hz flicker, but it's still not as good as the Sony X850F.
When Auto Motion Plus is enabled with the slider set to 0, the backlight flickers at 120Hz, as seen here. This creates a duplicated motion trail similar to when motion interpolation is enabled.
Similar to the Q8FN, the flicker varies depending on settings. There's almost no flicker in 'Movie' mode with the backlight at 100% and 'Auto Motion Plus' set to Custom.
There's an excellent black frame insertion feature to help reduce motion blur, which reduces flicker to 60Hz. To turn it on, you need to set Auto Motion Plus to 'Custom' and enable LED Clear Motion. The NU7100 can keep the flicker at 120Hz when in Game Mode, which can help with the appearance of motion. This is automatically enabled when in Game Mode.
Like the Q8FN, the flicker changes according to the settings.
The NU7100 can interpolate 30 fps content up to 60 fps. Known as the 'Soap Opera Effect,' this helps smooth out motion, but not everyone enjoys it.
By setting Auto Motion Plus to 'Custom' and adjusting the Judder Reduction to your liking, you can interpolate lower frame rate content. The frequency of the flicker depends on its settings.
The NU7100 is great at displaying content without stutter, even for low frame rate movies. The higher response time helps the transition between frames appear smoother.
The TV can't remove judder from 24 fps content played through a 60p/i cable box, or from native 24 fps content played from a Blu-ray. Most people aren't very sensitive to judder and won't see it.
The NU7100 doesn't support any of the variable refresh rate technologies like AMD's FreeSync. This was tested with an Xbox One S and with a Radeon RX 580.
When the input label is set to PC, the input lag is automatically the lowest possible. There's no benefit to activating Game mode within PC mode.
It supports most of the common resolutions without any issues. It doesn't support 1440p.
4k @ 60Hz with 4:4:4 or 4:2:2 chroma is only supported when HDMI UHD Color is enabled from the External Device Manager settings menu.
The TV includes breakout adapters for a composite or component connection. There's a shared connection on these and as such, it's impossible to connect a component and composite connection at the same time.
Like other 2018 Samsung TVs, this TV doesn't support DTS passthrough. This shouldn't be an issue as most content has both. For the audio return channel to work, Anynet+ (HDMI-CEC) must be enabled from the settings menu.
The NU7100 doesn't support 5 GHz wifi.
The frequency response is about average. LFE (low-frequency extension) is at 80Hz, which is above average. This means this TV won't produce any thump or rumble but will have a decent amount of punch to its bass. The response above the LFE is quite flat and well-balanced, which results in clear and understandable dialogue. However, since it 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 decently loud, but may not be loud enough for large and noisy environments.
There's a decent amount of distortion on the speakers of this TV. There's some noticeable total harmonic distortion (THD) at moderate listening levels, and it really increases when the TV is at its max volume.
The interface is similar to that of the NU8000 but lacks some of the more advanced features, including the Bixby voice assistance. It's easy to navigate, with a simplistic but modern design.
On the NU7100, there are very few animations. The interface is generally smooth, without much lag. When using an external device, the interface remains fluid, but when accessing the menus from within an app it would lag at times.
Like all Samsung TVs, there are ads. There's no option to disable them or to opt-out of ad tracking. During our testing there were ads, but we were unable to take a picture of them. They appear similar to the ads seen on the NU8000
Fantastic apps and features on the Samsung NU7100. There are a ton of apps available on Samsung's App Store, with a few common ones already downloaded on the TV. Unfortunately, navigating through the menus isn't very smooth.
This Samsung comes with a very basic remote. The buttons cover most of the basic functions, including inputs, quick access to the settings menu, and a picture size button to control the upscaling options for lower-resolution content.
There's a single button located underneath the TV, similar to the NU8000. Pressing the button brings up a menu that can power cycle the TV, control volume, channels, and change inputs.
We tested the 55" (UN55NU7100) version FA01. For the most part, we expect our review to be valid for the other sizes of this model.
If someone comes across a different type of panel or if their Samsung NU7100 doesn't correspond to our review, let us know and we will update the review.
Update 09/24/2018: We found the TV under a different model name, NU7200, at Walmart. We expect the TV to perform the same. If someone comes across any differences, let us know and we'll update the review.
Update 01/03/2019: We have received a report that at least one of the 43" variants is available in VA and IPS variants. At least version 03 of the UE43NU7120 has an IPS panel, as shown by this user-submitted image.
Update 01/25/2019: We have received a second confirmation of a 43" NU7170 with an IPS panel. The unit was purchased in Russia, and the panel is listed as version BC07.
