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. This is automatically activated when you are in Game Mode, as there is no other option to enable 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. See our recommendations for the best smart TVs.
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.
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.
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. Check also our recommendations for the best smart TVs and the best cheap TVs.
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, specifically, 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.
If you've got a bright room with wide seating, then the LG UK6300 is a better choice due to the better viewing angles. But for a dark room with seating directly in front, then the Samsung NU7100 is better due to its higher contrast ratio and better black uniformity. The LG UK6300 also has better reflection handing, and you can place it in a room with many light sources, whereas the Samsung NU7100 can get brighter to fight glare in a bright room.
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 two TVs are of different type, so if you have a room with wide seating arrangement, then the LG UK6570 might be a better suit due to the wide viewing angles, whereas in a darker room the blacks of the Samsung NU7100 are deeper and enhance the picture quality provided you sit straight in front. In terms of less critical differences, the LG UK6570 can handle reflections better and has a crisper image due to the faster response time.
The Samsung MU8000 is a better TV than the Samsung NU7100.

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 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.
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 TCL R617 6 Series is much better than the Samsung NU7100. The TCL R617 can deliver deeper blacks with its local dimming support, and this is great for watching movies in a dark room. The TCL 6 Series also has a faster response time and thus a smaller blur trail, and better HDR performance with highlights that pop. The Samsung NU7100, on the other hand, has a lower input lag which is great for fans of video games and better gray uniformity for an image without clouding.
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 faster response time, 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 LG B8 is significantly better than the Samsung NU7100 except for those who worry about burn-in. The LG B8 has perfect blacks, just like all OLEDs, that enhance the picture quality in a dark room. The LG has better reflection handling and a faster response time that leaves only a small blur trail when you watch fast action content like sports. The LG B8 also has better image accuracy when viewed from the side. The Samsung NU7100 has a lower input lag that makes it very responsive if you play video games.
The Samsung Q6FN is significantly better than the Samsung NU7100. The Samsung Q6FN can display a wider color gamut, great for HDR, and has a faster response time thus displaying a crisper image with less blur in fast motion. Finally, the Samsung Q6FN supports FreeSync VRR which is great for gaming.
