What it is: Type of display technology used by the TV.
When it matters: Different technologies have different performance and are suited to different uses
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 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.

Samsung NU7100 Design Picture
Curved : No

The design of the Samsung NU7100 is great. It incorporates design features found in higher-end models like the similar legs to the Q8FN (without the silver finish.) and the same back as the NU8000

Stand
Samsung NU7100 Stand Picture

The stand is modern and sturdy. It is wide enough to fit a soundbar in front.

Footprint of the 55" TV stand: 37.2" x 10.3"

Back
Samsung NU7100 Back Picture
Wall Mount : Vesa 200x200

The back of the TV has the same textured finish found in this year's NU8000. There are a few cable management tracks that span the entire width of the back of the TV. Also the TV comes with two clips that attach to the stand legs to also assist with cable management.

Borders

Borders : 0.55" (1.4 cm)

The borders of the Samsung UN55NU7100 are simple with a textured plastic finish and have average thickness.

Thickness

Max Thickness : 2.24" (5.7 cm)

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.

6.5 Build Quality
Samsung NU7100 Build quality picture

The build quality is ok. It feels solid even though it is almost entirely made from plastic.

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.

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.

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 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.

Pixels

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.

It is slightly worse than last year's MU6300, and similar to the MU7000. While it isn't bad, competing TVs from other brands like the LG UK6300 offer better motion performance.

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.

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.

Similar to the Q8FN, the flicker varies depending on settings. There is almost no flicker in 'Movie' mode with the backlight at 100% and 'Auto Motion Plus' set to Custom.

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 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 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 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.

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.

Sony X690E
50" 60" 70"

The Sony X690E is a versatile entry-level TV released in 2017. It is available in larger sizes and performs similarly to the Samsung NU7100. They have very similar picture quality but the X690E has better motion handling. Overall, the X690E is a bit better at almost everything.

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

The Samsung MU8000 is a good mid-range TV. It is better than the NU7100 in almost every aspect. It is brighter than the NU7100 but is slightly worse in a very dark room. It has better motion handling, but some people might notice the flicker a bit more. Most people should get the MU8000.

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

The 2017 Samsung MU6300 is very similar to the NU7100. The 6300 is brighter and has a better native contrast ratio. They have similar motion handling, but the NU7100 has lower input lag. Unless you are a gamer and want the absolute lowest input lag possible, the MU6300 is better for most people.

Samsung NU8000
49" 55" 65" 75" 82"

The Samsung NU8000 is a good mid-range LED TV. It is better than the NU7100 in almost every aspect. It produces a wider array of colors and is brighter, making for a much more enjoyable HDR experience. They are both great choices for gaming, but if you can afford the higher price of the NU8000, it is a much better TV.

I can't understand why Samsung would have such an inferior contrast ratio from last years comparable model. Even though you say the new model does a good job, nothing replaces that HUGE difference in contrast numbers IMHO.

I watch most of my TV at night after work not in a fully lit room.

We don't understand it either, but while the native contrast is a lot lower than last year, it isn't bad per se. It is on the low end for a VA panel, but is still much higher than an IPS panel. In a dimly lit room most people won't notice it too much, it would be mostly noticeable in a completely black room.
