The Samsung NU6900 is an alright entry-level 4k TV. It's available in a wide range of sizes with budget-friendly prices, and it provides okay overall performance. It has a VA panel with an outstanding contrast ratio and excellent black uniformity, so it's an ideal choice for watching movies in a dark room. However, it's limited on extra features, as it lacks local dimming and can't remove judder from any source. HDR content doesn't look all that good either, as it doesn't display a wide color gamut and doesn't get bright enough to make highlights pop. It's a decent choice for casual gamers as it has low input lag, but its slow response time results in some motion blur.

Our Verdict

6.8 Mixed Usage

The Samsung NU6900 is an okay TV for mixed usage. It has an outstanding contrast ratio that makes blacks appear deep when viewed in a dark room. It's not suitable for watching shows or sports in bright rooms because it doesn't get very bright, but it has decent reflection handling. On the upside, the input lag is low, making it decent for gaming.

Pros
  • Outstanding contrast ratio.
  • Excellent black uniformity.
  • Decent reflection handling.
Cons
  • Narrow viewing angles.
  • Doesn't get very bright.
  • Fails to display wide color gamut.
6.5 Movies

The Samsung NU6900 is alright for watching movies. It has an outstanding contrast ratio and excellent black uniformity, making it a great choice for watching movies in dark rooms. However, it lacks a local dimming feature to further improve black scenes. It also can't remove 24p judder from any source.

Pros
  • Outstanding contrast ratio.
  • Excellent black uniformity.
Cons
  • Doesn't remove judder.
  • No local dimming feature.
7.2 TV Shows

The Samsung NU6900 is decent for watching TV shows. It has decent reflection handling, but it doesn't get bright enough to combat glare in well-lit rooms. It's very good at upscaling cable content and should keep most TV show enthusiasts happy. Unfortunately, it has narrow viewing angles, so you won't get an accurate image when viewing from the side.

Pros
  • Decent reflection handling.
  • Upscales lower-resolution content well.
Cons
  • Narrow viewing angles.
  • Doesn't get very bright.
6.9 Sports

The Samsung NU6900 is okay for sports. It has decent reflection handling so you can place it in an average-lit room, but it doesn't get bright enough to combat a lot of glare. Unfortunately, it has narrow viewing angles and it's not ideal for wide seating arrangements. Additionally, it has a slow response time, so fast-moving content may look blurry.

Pros
  • Decent reflection handling.
  • Upscales lower-resolution content well.
Cons
  • Narrow viewing angles.
  • Doesn't get very bright.
  • Slow response time.
7.0 Video Games

The Samsung NU6900 is decent for playing video games. It has a low input lag, which makes it very responsive, but it has a slow response time that makes motion look blurry. However, it has a Black Frame Insertion feature to improve the appearance of motion. Unfortunately, it doesn't have support for any variable refresh rate technology to improve the gaming experience further.

Pros
  • Outstanding contrast ratio.
  • Excellent black uniformity.
  • Low input lag.
Cons
  • Slow response time.
  • No VRR support.
6.3 HDR Movies

The Samsung NU6900 is mediocre for watching HDR movies. It has an outstanding native contrast ratio and excellent black uniformity but lacks local dimming to make blacks deeper. Furthermore, it doesn't have a wide color gamut and can't get very bright to make highlights pop and deliver HDR content as the director intended.

Pros
  • Outstanding contrast ratio.
  • Excellent black uniformity.
Cons
  • No local dimming feature.
  • Doesn't get very bright.
  • Fails to display wide color gamut.
6.7 HDR Gaming

The Samsung NU6900 is okay for HDR gaming. It has a low input lag in HDR, but it has a slow response time that results in some motion blur. It also has an outstanding contrast ratio and excellent black uniformity. Unfortunately, the TV can't display HDR content as intended because it can't get very bright and doesn't have a wide color gamut.

Pros
  • Outstanding contrast ratio.
  • Excellent black uniformity.
  • Low input lag.
Cons
  • Doesn't get very bright.
  • Slow response time.
  • Fails to display wide color gamut.
6.9 PC Monitor

The Samsung NU6900 is alright for use as a PC monitor. It has low input lag, and it can display most common resolutions and chroma 4:4:4, which is important for reading text. Unfortunately, the viewing angles are bad, so the edges of the screen appear darker if you sit too close. It doesn't get bright enough to combat glare, but it has decent reflection handling.

Pros
  • Decent reflection handling.
  • Low input lag.
  • Displays chroma 4:4:4.
Cons
  • Narrow viewing angles.
  • Doesn't get very bright.
  • Slow response time.

Test Results

Market Context

Market Context

The Samsung NU6900 is the entry-level 4k TV in Samsung's 2018 lineup. It sits below the Samsung NU7100 and replaces the Samsung MU6100. It competes with other entry-level TVs, such as the Sony X750F, LG UK6300, and the Vizio E Series 2018.

Design
8.5
Design
Style
Curved No

The Samsung NU6900 has an excellent design, which is similar to the higher-end model, the Samsung NU7100. The stand holds up the TV well, and the thin design means that it doesn't bulge out too much when wall-mounted. Also, the TV casing is made out of plastic, but it doesn't look too bad. The overall build quality is okay.

Design
Stand

The stand is plastic and supports the TV well. It's slightly different from the Samsung NU7100's stand. Unfortunately, it isn't very tall and you may block a small part of the bottom edge of your screen if you place a soundbar in front of it.

Footprint of the 55" TV stand: 39.75" x 9.5"

Design
Back
Wall Mount VESA 200x200

The back is made out of plain plastic. There's an opening at the bottom edge for cable management.

Unfortunately, there are only two HDMI inputs, so you can only connect two devices at once. However, all inputs are side-facing, so they're easier to reach if you mount wall-mount the TV.

Design
Borders
Borders 0.55" (1.4 cm)

This TV has fairly thick bezels, but they shouldn't be too distracting.

It's fairly thin and shouldn't stick out much when wall-mounted.

Build Quality

The build quality is okay. There aren't any gaps and you shouldn't have issues with it, but the cheap, plastic feeling is apparent everywhere with this TV.

The peak brightness isn't bad. It can't get very bright in SDR to overcome glare. It's more suitable for dimmer rooms, very similar to 2018's Samsung NU7100, but less bright than the 2017's Samsung MU6100 or Samsung MU6300. Even though the brightness is mostly consistent, small highlights aren't as bright, as we can see from our 2% window. This is due to Samsung's CE (frame) dimming.

The HDR peak brightness is disappointing. Although it's fairly consistent across most input windows, it's just not bright enough to deliver the director's intent. Small highlights in dark scenes get crushed.

The Samsung NU6900's gray uniformity is decent, but this may vary between units. The edges of the screen are visibly darker, and there's some dirty screen effect in the center. The uniformity is much better in near-dark scenes.

The Samsung NU6900 has impressive out-of-the-box color accuracy, but this may vary between units. Setting the Picture Mode to 'Movie' delivers the best performance, and it's hard to detect any inaccuracies with the white balance dE and color dE. Gamma doesn't follow the target curve all that well and most scenes are brighter than they should be. Color temperature is slightly colder than our 6500K target, giving the image a blueish tint.

After calibration, the color accuracy is remarkable. The calibration used a 100% sized window instead of 18%. The white balance calibration used the 10-point grayscale, and there weren't any problems with performance. As with most Samsung TVs, most of the correction of the color dE came from the correction of white balance, because changing the values through the color space management didn't make the results any better. Even professionals will have a hard time finding the color inaccuracies post-calibration, and it's nearly impossible to see any gray inaccuracies as well. The temperature hit our target of 6500K and the gamma curve was corrected.

This TV has an okay color gamut, but it's not considered a wide color gamut for HDR content. In the 'Movie' Picture Mode, the EOTF curve follows the target curve fairly well until it rolls off. The PC and Game mode EOTFs are very similar to 'Movie'.

If you find HDR content too dim, you can set Contrast Enhancer to 'High' and raise the Gamma to '+3'. This results in a brighter image, as you can see in this EOTF.
