The Samsung NU6900 is a decent entry-level 4K LCD TV. It has an okay picture quality with a high native contrast ratio but lacks other more advanced features like local dimming to enhance image quality. It can't get very bright and does not have a wide color gamut, so it cannot deliver good HDR performance. It has a low input lag and a fast response time which are good for games, but motion handling is only mediocre.

Design

Score components: Subjectively assigned
Samsung NU6900 Design Picture
Curved : No

The design of the Samsung NU6900 is excellent and very similar to the higher end model NU7100. The TV casing is made of plastic but this does not look bad. The stand supports the TV well and the TV is very thin. If wall mounted, it will not protrude much. The build quality is decent and should not cause any issues.  

Stand
Samsung NU6900 Stand Picture

The stand of the Samsung NU6900 is plastic and supports the TV well. It is slightly different from the stand of the NU7100. Unfortunately, it is not very tall and you might 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"

Back
Samsung NU6900 Back Picture
Wall Mount : VESA 200x200

The back of the screen is almost identical to the Samsung NU7100. It is plastic and very plain. There is one vent on the top of the back and some grooves across the bottom edge for the cable management.

All inputs are facing sideways and should not be hard to reach if you wall mount the TV. Unfortunately, there are only 2 HDMI ports and that limits the number of devices you can connect simultaneously to the TV.

Borders
Samsung NU6900 Borders Picture
Borders : 0.55" (1.4 cm)

The borders are of average thickness with a thick bezel. They are made entirely out of plastic with a gloss finish and fingerprints show easily.

Thickness

Max Thickness : 2.36" (6.0 cm)

One of the good aspects of this TV's design is its thickness, it is fairly thin and will not protrude much if wall mounted.

The TV gets fairly warm at the bottom edge where the array of LEDs is. This, however, should not be an issue.

6.5 Build Quality

The build quality of the NU6900 is okay. There are no gaps and you should have no issues with it but the plastic feeling is apparent everywhere with this TV.

7.4

Picture Quality

The Samsung NU6900 has a decent picture quality with excellent contrast ratio and great out of the box color accuracy. It cannot get bright enough to overcome glare and it cannot display the director's intent when displaying HDR content due to the lack of a wide color gamut and the crushing of highlights. Viewing angles are bad, and reflection handling is decent. A small dim room is the best environment for this TVs picture quality.

The native contrast of the Samsung NU6900 is excellent. It is one of the highest native contrast ratios we've measured so far in LED TVs and in the same ballpark with more expensive models like the Samsung Q7FN. Unfortunately, the TV does not support a local dimming feature to further improve contrast.

Decent SDR peak brightness. The Samsung NU6900 cannot get very bright in SDR to overcome glare. It is more suitable for dimmer rooms, very similar to this year's NU7100, but less bright than last years MU6100 or MU6300. Even though the brightness is mostly consistent, in dark scenes, small highlights are not as bright as we can see from our 2% window and this is due to Samsung's CE (frame) dimming.

The HDR peak brightness of this NU6900 is disappointing. Although it is consistent across most input windows, it's just not enough to deliver the directors intent. Small highlights in dark scenes get crushed. The TV has similar performance to the budget LG UK6300 and its performance, just like the NU7100, is worse than last year's Samsung lineup.

The gray uniformity of the Samsung NU6900 is decent. Although the corners are slightly darker, the center of the image is relatively clear and it is unlikely that you will notice any dirty screen effect when watching sports. This performance is similar to higher-end Samsung models like the NU7100.

In darker shades of gray, the results are better and only very few people might notice any shades on the screen.

Bad viewing angles for the Samsung NU6900, an almost identical result with that of the NU7100. Unfortunately, small movements off the center axis and the picture fades to gray as blacks become more intense. This is an expected behavior of VA-panels.

Decent reflection handling, although towards the lower end of the scores. Looking at this years' Samsung models, only the NU7300 and NU8500 are slightly worse. The semi-gloss filter diffuses reflections across the screen thus diminishing their intensity. This is good for average lit rooms but in very bright rooms, it can be distracting.

Excellent out of the box color accuracy for the NU6900. The second best of the Samsung models we've tested thus far, right behind last year's Samsung MU8000 and better than this years best Samsung Q6FN.

The Picture Mode with the best results is the 'Movie'. White balance dE and the color dE are low making it hard to detect any inaccuracies. The color temperature is slightly colder than our 6500 K target, and the average gamma is not far from our 2.2 target. However, the gamma curve is not following closely our target curve.

Almost perfect color accuracy after calibration for this Samsung UN55NU6900, better than this years' best Samsung Q6FN. We performed the calibration using a 100% windows instead of the 18% size window. The white balance calibration was done using the 10 point grayscale and was performed without any issues. Changing the values through the color space management did not improve results and thus most of the correction of the color dE came from the correction of the white balance, which is typical for Samsung TVs. After calibration, it's almost impossible to detect gray inaccuracies and the color inaccuracies left behind will be hard to spot even by professionals. The gamma curve was corrected and the color temperature was at our target of 6500 K.

Samsung NU6900 EOTF

This TV does not have a wide color gamut. Just like the Samsung NU7100, the NU6900 is best suited for SDR content as it cannot display saturated colors very well. In the 'Movie' Picture Mode that gives the best results in HDR, the EOTF curve follows closely the target PQ curve until the TV gets closer to its peak brightness when it quickly starts to roll off. The PC and Game mode EOTFs are very similar to 'Movie'.

If while watching an HDR movie or while playing an HDR game you find the image too dark, you can set Contrast Enhancer to 'High', or raise the Gamma. Here is the EOTF with both Contrast Enhancer set to 'High' and with a Gamma correction of '+3'.

Motion

The motion handling of the Samsung NU6900 is only mediocre. The response time is good but the TV has flicker at 120Hz which might bother some people. Its motion interpolation features are decent and the BFI feature helps make the image crisper. Unfortunately, just like the rest of the lower end models of the NU line of products, the NU6900 cannot remove 24p judder from any source.

PWM Dimming Frequency
What it is: The flicker frequency of the screen, when all optional flicker has been disabled.
When it matters: All usages, but particularly when viewing fast motion (such as in sports and video games) or when using the TV as a PC monitor.
Good value: 0 Hz or very high frequencies (> 300 Hz). Frequencies that are multiples of 60Hz are better.
:
120 Hz

The TV dims without much flicker for Backlight setting from '50' to '25'. Then it uses PWM flicker to dim for Backlight setting from '24' to '0'.

When the Backlight is set between '50' and '25' you will not notice any flicker, but instead you will notice more motion blur. As you lower the Backlight from '24' to '0', flickering will intensify and you will notice less blur along with the lower levels of brightness. Most people will not be bothered by the 120Hz flicker, but more sensitive people might be. During motion this flicker causes double image artifacts, as seen in our Motion Blur photo.

8.6 Black Frame Insertion (BFI)
What it is: How effective the TV's flickering capabilities are in making motion look clearer, when flicker is desired.
When it matters: When flicker is desired by the user. Flicker is especially useful to make motion look clearer when viewing 60 fps content (sports, video games) and when using motion interpolation.

When it matters: When playing video games with fast motion.
Good value: 60 Hz
Noticeable difference: 20 Hz
:
120 Hz

The Samsung NU6900 allows you to reduce the flicker frequency to 60 Hz, to reduce persistence blur. As in all Samsung models, to activate it you must set LED Clear Motion to 'Custom', and enable LED Clear Motion. You cannot activate 60 Hz black frame insertion when in 'Game' mode so the only flicker will come from the 120Hz native flicker in the Backlight levels of less than 24.

Note that when you enable the BFI, the perceived brightness of the TV is reduced no matter the Backlight levels.

7.0 Motion Interpolation
What it is: Also known as 'Soap Opera Effect'. It is an optional feature that increases the frame rate of the video, smoothing movement.
When it matters: If you like the look of smoothed video. Not everyone does.
Samsung NU6900 Motion Interpolation (30 fps) Picture
Motion Interpolation (30 fps)

What it is: Whether the TV can take a 60 fps input and heighten the frame rate to at least 100 fps.
When it matters: 60 fps videos. Includes some video games, some sports channels.
:
No

The Samsung NU6900 can interpolate 30 fps content up to 60 fps. Motion appears more fluid but it introduces some 'Soap Opera Effect' that some people do not like. To enable interpolation, set Auto Motion Plus to 'Custom', and adjust the Judder Reduction slider to your preference.

The TV stops interpolating when the motion gets too intense just like Samsung NU7100.

7.9 Stutter
What it is: Jarring effect caused by static frame time during motion sequences
When it matters: When watching content with long panning shots and other smooth movement

Sound Quality

What it is: How well and accurately the audio is reproduced.
When it matters: When a good and accurate sound reproduction is needed.
Score components:

The sound quality of the Samsung NU6900 is decent. This TV gets decently loud, but may not be loud enough for larger and noisier environments. It also has a decent bass, but doesn't produce any thump or rumble in the sub-bass range and lacks a bit of punch and body to the bass as well. However, it produces clear and intelligible dialog and has low distortion. For a better sound, dedicated speakers or soundbars are recommended.

Compared to other TVs

Samsung NU6900 Group Shot Picture
Top left: Vizo E Series 2018 (E65-F1). Bottom left: LG UK6300 (43UK6300PUE). Middle: Samsung NU6900 (UN55NU6900). Top right: Samsung NU7100 (UN55NU7100). Bottom right: TCL S405 (43S405).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Samsung NU6900 is an entry-level 4k TV. It is aggressively priced but you can find better TVs in the same price range.

Samsung NU7100
40" 43" 50" 55" 58" 65" 75"

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.

LG UK6300
43" 49" 50" 55" 65"

If you've got a room with wide seating, then the LG UK6300 is a better choice due to the better viewing angles its IPS panel provides. If you are sitting directly in front of the TV, then the Samsung is a better choice. The Samsung NU6900 has better picture quality and is a better choice for movies in a dark room as it displays deeper blacks due to the better native contrast ratio and better black uniformity. The NU6900 can get brighter and is slightly better for watching TV shows. The LG UK6300, on the other hand, has better reflection handling for a room with many but not too bright lights.

TCL S517
43" 49" 55" 65"

The TCL 5 Series S517 and the Samsung NU6900 both have very similar performance. The TCL S517 is a better choice for watching movies as it has better motion handling and can remove 24p judder from movies. On the other hand, the Samsung NU6900 has better black frame insertion performance and can make the image crisper which is important if you watch a lot of fast action sports.

Vizio M Series 2018
55" 65" 70"

The Vizio M Series 2018 is better than the Samsung NU6900. The M Series 2018 has a local dimming feature that makes blacks look deeper in a dark room and is a better choice for watching movies. The Vizio M Series 2018 is also more suitable for a bright room as it has better reflection handling and can get much brighter, and has a faster response time making it better for watching fast action such as sports or playing video games. On the other hand, the Samsung NU6900 is equipped with better smart features.

LG UK6570
70" 75" 86"

The LG UK6570 is a bit better than the Samsung NU6900, unless dark room performance is important. The UK6570 has wider viewing angles than the NU6900 and better reflection handling, making it a better choice for bright rooms with lots of side seating. The UK6570 has a faster response time, so motion looks clearer with less blur trail. The NU6900 has a VA panel, and is better suited for a dark room with no side seating.

Insignia Fire TV
43" 50" 55"

The Samsung NU6900 is much better than the Insignia Fire TV. The Samsung NU6900 has lower input lag and better response time which is great if you play fast action video games. The Samsung NU6900 also has better black uniformity which is great for dark room performance and better reflection handling which makes it a better choice for a room with many light sources.

B&H

7.4Mixed Usage
What it is: General purpose. The TV will be used for a variety of content and usages. Movies at night, TV shows during the day, video games from time to time, etc.
Score components:
The Samsung NU6900 is a decent TV for mixed usage. It has an ordinary picture quality with low input lag that makes it responsive, which is good for gaming, and an excellent native contrast ratio that allows it to display deep blacks in a dark room. It has decent reflection handling, but since it can't get very bright, it is not suitable for very bright rooms.
6.7Movies
What it is: Movies in the dark. The TV will be used for watching movies in a controlled environment, directly in front, in a home theater way. Mostly only high quality content, like Blu-rays, UHD Blu-rays, streaming and a little bit of HDR.
Score components:
This TV has a mediocre performance in movies. Although it has an excellent native contrast ratio, it does not have features like local dimming to improve picture quality in a dark room where movies are meant to be watched. Furthermore, the mediocre motion handling performance will not make movie enthusiasts happy.
7.5TV Shows
What it is: TV Shows in a bright living room. The TV will be used in to watch TV shows, in a bright room during the day, from multiple viewing positions at different angles. The content watched has an average quality: cable, streaming, SD channels, etc.
Score components:
The Samsung NU6900 is a good TV for watching TV shows. It has decent reflection handling and can get decently bright for an average lit room. The NU6900 is very good at upscaling cable content and will keep most TV show enthusiasts happy. It also has an option to add motion interpolation for those who enjoy the soap opera effect.
7.2Sports
What it is: Sports in a living room. The TV will be used to watch sports during the day, like football or hockey. Usually watched with a group, so from multiple viewing position.
The Samsung NU6900 is a decent TV for watching sports. It has decent reflection handling so you can place it in an average lit room with a few light sources, and a very fast response time so that fast action has very little blur. The gray uniformity is decent and it is unlikely that you will notice any dirty screen effect when watching sports. Unfortunately, the viewing angles are bad so it is not suitable for wide seating arrangements.
8.1Video Games
What it is: Video games. The TV will be used to play video games, directly in front, in a controlled light environment. Usually fast games, like online FPS, where motion blur and input lag is important.
This is a good TV for playing video games. It has a very low input lag which makes it very responsive, and a very fast pixel response time so that fast action has little blur. It supports flicker to make the image crispier, but unfortunately, it does not have support for any variable refresh rate technology to improve the gaming experience further.
6.8HDR Movies
What it is: HDR Movies and TV shows. The TV will be used to watch 4k UHD HDR content, with a wide color gamut and a high peak brightness. Either via UHD Blu-rays or HDR streaming.
Score components:
This is a decent TV for watching HDR movies. The TV has excellent native contrast ratio but lacks local dimming to make blacks deeper and improve picture quality in a dark room. Furthermore, it cannot get very bright and does not have a wide color gamut to make highlights pop and deliver the content as the director intended.
7.6HDR Gaming
What it is: HDR Gaming. The TV will be used to play HDR video games using consoles that support it or on current generation gaming PCs. Xbox One S, PS4 Pro, GTX 10 series and AMD RX series graphics cards.
The Samsung NU6900 is a good TV for HDR Gaming. This is due mainly to the very low input lag at 4k @ 60Hz + HDR and the fast response time that leaves only a little blur in fast action. Unfortunately, the TV cannot display HDR content as the director intended as it cannot get very bright and does not have a wide color gamut. Therefore, although it will be responsive when gaming in HDR content, the picture quality will not be what you would expect.
7.8PC Monitor
What it is: PC Monitor. The TV will be used as a PC monitor, from 2-3 feet away, either for productivity purposes or gaming. Sharp text is important, as well as a high resolution.
Score components:
The Samsung NU6900 is a good TV for use as a PC monitor. It has low input lag, a very fast response time and can display most common resolutions. It supports chroma 4:4:4 and this mean that you will get a clear image when you use it as a PC. Unfortunately, the viewing angles are bad and if you sit close to the screen, the edges will look darker.
