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.
The TV looks thin when viewed from the side and resembles the also new NU8000. It too lacks the OneConnect mini, saving you the trouble of where to place it when wall mounting the TV. At the same time, changing connections is not a as simple as with the OneConnect.
The NU7100 gets warm along the bottom edge of the panel where the LEDs are. This is common for many Samsung models and should not be a problem.
The Samsung NU7100 produces decent picture quality. It has a good native contrast ratio, but it is lower than normal for this type of panel. It isn't very bright either, especially in HDR, and is better suited for viewing in a dim room. It has good gray uniformity, with very little dirty screen effect, great for sports fans. It has a limited color gamut, and poor color volume, so it performs its best with SDR content. It has great reflection handling.
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 have reset the TV and retested the native contrast ratio, and it is a bit higher. It is likely that the calibration raised the black levels slightly, lowering the previously measured contrast ratio.
The Samsung NU7100 does not have a local dimming feature. The above video is provided for reference only.
Disappointing HDR peak brightness. It is fairly consistent across all input windows. Small highlights in dark scenes are dimmed by the TV's algorithms, as shown by our 2% window test. Like with SDR, the HDR performance is worse than last year's Samsung lineup. Similar performance to the budget-level LG UK6300.
The TV has a good gray uniformity. In the 50% gray test picture you can notice it is a little darker on the sides and especially on the corners. This fades as we move towards the center of the screen where things are pretty even and thus, the minor dirty screen effect is hardly noticeable. This is very good for those who will use the TV mostly for sports viewing.
The 5% gray uniformity is very good with no noticeable brighter spots.
The Samsung NU7100 has a poor viewing angle, but it is better than last year's MU6300. The black levels shift dramatically when viewing even slightly off center.
The Samsung NU7100 has an excellent black uniformity, similar to the 2017 MU6300 and one of the best among LED TVs. The are no clouding issues and black looks very uniform. As a result, dark scenes in movies look great.
Out of the box color accuracy is decent. The Movie picture mode provided the most accurate settings. White balance and color dE are a bit high but most people won't notice a huge difference. Gamma is high, and color temperature is a bit warm.
After calibration with the Movie picture mode, the white balance is almost perfect and colors are much better. Gamma follows our target 2.2 almost perfectly, although the color temperature is a little off from our target of 6500K.
See our recommended settings here.
The NU7100 supports a standard color gamut only 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 is unable to produce deep, dark colors, and it is 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 is 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.
The motion handling of the Samsung NU7100 is mediocre. The refresh rate is decent, but in dark scenes, it is a bit high so sci-fi fans might be a bit disappointed. The backlight has improved over the MU6300, and it now flickers at 240 Hz, which is less noticeable. It can also reduce the backlight frequency to 60Hz, helping motion appear smoother but introducing visible flicker. The NU7100 cannot remove judder from any source, although most people won't notice this.
Decent response time. In dark scenes like our 20% test slide the 100% transition is very slow and there is some motion trail.
Most of the blur in the above photo is due to duplications caused by the backlight flicker.
The Samsung NU7100 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. This year's model is an improvement over the MU6300 with its 120Hz flicker, but it is 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.
The TV has an optional black frame insertion feature to help motion appear smoother. When enabled, this feature reduces the flicker frequency to 60Hz. As on all Samsung TVs, this is enabled by setting 'Auto Motion Plus' to Custom, and enabling 'LED Clear Motion'.
New to this year's NU7100 is the ability to keep the 120Hz flicker when in game mode. This can help motion in games appear smoother if you don't mind the visible flicker.
The TV is able to interpolate 30 fps content up to 60 fps, the native refresh rate of the panel. This can help motion appear more fluid, but some people don't like the Soap Opera Effect this causes. To enable it, set 'Auto Motion Plus' to Custom, and adjust the 'Judder Reduction' slider to your preference.
In motion scenes there are visible artifacts, when the motion gets too intense the TV stops interpolating.
The Samsung UN55NU7100 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 cannot 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 Samsung NU7100 does not 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.
The Samsung NU7100 has excellent low input lag and supports most common resolutions, except for 1440p which is becoming popular with gamers. The input lag is extremely low when in PC or Game mode, among the lowest measured. It supports chroma 4:4:4 without any issues, which combined with the low input lag, makes it a good choice for a PC monitor. Like all Samsungs we have reviewed recently, there is no DTS passthrough; this shouldn't be an issue since most sources have both audio formats.
Excellent low input lag. When Game mode is activated, the TV bypasses all processing. This is among the best input lags of any TV, better than similar models from last year like the MU6300, and almost as good as this year's LG UK6300.
When the input label is set to PC, the input lag is automatically the lowest possible. There is no benefit to activating Game mode within PC mode.
The NU7100 supports most of the common resolutions without any issues. It doesn't support 1440p.
4k @ 60 hz 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 is a shared connection on these and as such, it is impossible to connect a component and composite connection at the same time.
Like other 2018 Samsung TVs, the NU7100 does not 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 does not support 5 Ghz wifi.
The Samsung NU7100 has an average sound. This TV doesn't have deep bass and won't produce any thump or rumble, but has a decent amount of punch to its bass and produces clear and intelligible dialogs. It also gets decently loud but may not be loud enough for large and noisy environments. For a better sound, dedicated speakers or soundbars are recommended.
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 intelligible dialogs. 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.
The distortion performance is about average. The overall amount of harmonic distortion at 80dB SPL is decent. The produce THD doesn't rise dramatically at maximum volume either, which is good but the TV doesn't get very loud.
The Samsung NU7100 has the same interface as the NU8000, minus the Bixby voice assistant. The interface is easy to navigate and works well, although there are some issues with lag when accessing the interface from within an app. Like all Samsung TVs, there are ads and they cannot be removed. The remote app is very basic, far simpler than the remote apps from the other TV manufacturers.
The interface is similar to that of the NU8000 but lacks some of the more advanced features, including the Bixby voice assistance. It is 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 is 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
Samsung's App Store has one of the widest selections of apps, second to the Google Play Store on Sony TVs. There are a few apps preinstalled, the same ones found on most TVs (Amazon Video, Netflix, YouTube, etc...).
The Samsung 55NU7100 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.
Samsung's SmartThings app can be used as a replacement remote but the options are very limited. Although it is possible to act as a full remote control of the TV, it cannot change inputs directly (it is necessary to navigate the on-screen menus). Like most remote apps, it cannot be used to input text.
There is 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.
The Samsung NU7100 is a versatile entry-level 4k TV with decent picture quality. It is aggressively priced, but there are better TVs out there in the same price range.
The Samsung NU7100 and the Samsung NU6900 both have very similar performance. The Samsung NU7100 has better input lag that is important if you play video games or HDR video games. Also, the low input lag makes the NU7100 a slightly better choice for use as a PC monitor. On the other hand, the NU6900 has a marginally better response time, so fast action has less blur.
The Samsung NU8000 is much better than the Samsung NU7100. The NU8000 is much brighter with all types of content. Motion is smoother as it can remove 24p judder from almost all sources and the faster response time means less motion blur. The NU8000 also has some advanced gaming features, including automatic low latency mode and support for a variable refresh rate.
The Samsung NU7100 4k TV is slightly better than the Samsung MU6290.

The NU7100 also has better input lag for gamers or for use as a PC monitor. The Samsung MU6290 is a bit brighter with SDR content.
The Samsung NU7100 is a bit better than the Sony X720E, unless you have a wide seating area. The NU7100 uses a VA panel, and is better for a direct seating arrangement but has better dark performance due to the better contrast and better black uniformity. The X720E uses an IPS panel which has much wider viewing angles but is not recommended for a dark room.
The Samsung NU7100 is marginally better than the Samsung MU7000. The NU7100 has better black uniformity and slightly better reflection handling. The MU7000 has excellent low input lag, but the NU7100 is even better. The MU7000 is a bit brighter in SDR and HDR.
The Samsung MU8000 is a better TV than the Samsung NU7100. The Samsung MU8000 has much better motion handling as it has a judder removal feature and better response time which is great for movies and video games and has better local dimming which improves blacks and picture quality when you watch a movie in a dark room. On the other hand, the Samsung NU7100 has somewhat better black uniformity which is good when watching HDR movies and a bit better input lag when sent 4k @ 60hz + HDR signal for HDR gaming.
The Samsung NU7300 is marginally better than the Samsung NU7100. The NU7300 is a touch brighter, and has a slightly faster response time but this may be just due to small variances between panels. Overall, there is no major difference between the two though. The NU7100 is available in a wider variety of sizes.
The Samsung NU7100 and the Sony X690E have very similar performance. The Sony X690E has a faster response time and thus a smaller blur trail in fast action sports. The Samsung, on the other hand, has lower input lag and is very responsive when you play video games or use the TV as a PC monitor. The Samsung NU7100 also has better blacks due to the better native contrast ratio and better black uniformity, and this matters if you watch movies in a dark room. Finally, the Samsung NU7100 has a better brightness, which is great if you watch TV shows in a bright room.

The Samsung MU6100 has better reflection handling and SDR peak brightness, which is good if you watch TV shows in a bright room.
The LG UK7700 is a better TV than the Samsung NU7100. The LG has better reflection handling, better response time, and wider viewing angles due to its IPS panel, so watching sports and TV shows on the LG is a very good experience. On the other hand, the Samsung NU7100 will offer a better experience in HDR movies due to the much better contrast ratio that can produce deep blacks in a dark room.
The Vizio E Series 2018 is somewhat better than the Samsung NU7100. The Vizio E has better reflection handling, and supports local dimming, even though it isn't very effective. The Vizio produces clearer motion with less blur thanks to the higher native refresh rate, and it is more effective at removing judder from 24p sources. The Samsung NU7100 has an optional motion interpolation feature, which is great if you enjoy the soap opera effect.
The Samsung NU7100 and the Vizio D Series 4k 2018 have very similar performance. The Vizio D Series 4k 2018 has a faster response time which is great for fast action. It can get slightly brighter and can handle reflections better which is great for watching TV shows. The Samsung NU7100, on the other hand, has lower input lag for gaming and better motion interpolation for those who like the soap opera effect. It also has slightly better 720p upscaling that is better if you watch a lot of cable TV.
The Samsung NU7100 is a slightly better TV than the Samsung MU6500. The Samsung NU7100 has better input lag for video games, and a marginally better input lag when sent 4k @ 60hz + HDR signal for HDR gaming. The Samsung NU7100 also has a slightly better black uniformity which becomes apparent in a dark room when you watch HDR movies. On the contrary, the Samsung MU6500 is slightly better for use as a PC monitor due to its curved profile and has a marginally better response time which is great for video games.
The Samsung NU7100 is better than the Toshiba Fire TV 2018. The Samsung NU7100 has a lower input lag, which is great if you play video games or use the TV as a PC monitor. The Samsung NU7100 also has better black and gray uniformity that improve picture quality and better reflection handling, which allows you to place the TV in a room with many small windows. On the other hand, the Toshiba Fire TV 2018 can get brighter and so it can fight the glare of bright rooms better, and it has better handling of fast motion due to the faster response time.
If you have a room with wide seating arrangement, the Sony X750F is a better choice than the Samsung NU7100 as it has better viewing angles. But if you have a dark room with seating directly right in-front, then the Samsung NU7100 is better. The Samsung has deeper blacks, and you will enjoy watching movies more. The Samsung also has lower input lag, and this is great if you play video games. On the other hand, the Sony can remove 24p judder from older content.
The Samsung NU7100 is marginally better than the Samsung MU7600. The Samsung NU7100 has lower input lag in SDR and 4k @ 60hz + HDR, which is great for gaming. It also has slightly better black uniformity which makes blacks look better in a dark room. On the other hand, the Samsung MU7600 is curved and has a better brightness that is good for brighter rooms, and a wider color gamut and color volume that makes HDR content look better.
The Samsung NU7100 is a bit better than the LeEco Super4. The NU7100 has better black uniformity that makes dark room viewing more enjoyable. Motion looks clearer on the NU7100 due to the much better optional black frame insertion feature, and the NU7100 has less input lag. The LeEco Super4 has slightly better reflection handling, and a faster response time.
