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.

Our Verdict

6.6 Mixed Usage

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.

Pros
  • Excellent low input lag.
  • Good uniformity.
Cons
  • Limited HDR capabilities.
  • Picture quality degrades when viewed at an angle.
6.6 Movies

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.

7.2 TV Shows

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.

6.4 Sports

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.

6.9 Video Games

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.

6.3 HDR Movies

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.

6.5 HDR Gaming

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.

6.8 PC Monitor

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.

  1. Update 5/21/2020: Converted to Test Bench 1.5.
  2. Update 2/21/2020: Converted to Test Bench 1.4.
  3. Update 2/28/2019: Converted to Test Bench 1.3.
  4. Update 6/15/2018: The TV's picture settings have been reset and the contrast ratio has been remeasured at a higher value of 5397:1. It is likely that the calibration raised black levels slightly, reducing the native contrast ratio. The new measurement is in-line with other Samsung TVs like the NU7300.

Design
Style
Curved No

The NU7100 has a fantastic style, similar to the higher-end Samsung NU8000, although it uses the same legs as the Samsung Q8FN/Q8/Q8F QLED 2018. It has a simple, modern design with a flat back so it doesn't stick out too much when wall-mounted.

Design
Stand

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"

Design
Back
Wall Mount VESA 200x200

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

Design
Borders

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.

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.

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.

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.

Decent response time. In dark scenes like our 20% test slide, the 100% transition is very slow and there's some motion trail.

It's slightly worse than the 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.

PWM Dimming Frequency
240 Hz

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.

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 the MU6300, and almost as good as the LG UK6300.

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.
