Resolution : 4k

The Samsung RU8000 is a very good 4k TV with good picture quality. It delivers deep uniform blacks in a dark room, but lacks a local dimming feature to further improve dark room performance. The RU8000 has good SDR peak brightness and good reflection handling. The TV has a wide color gamut, but HDR peak brightness is only mediocre, so it can't display small highlights as they should be. The overall gray uniformity is good with just minimal dirty screen effect, but the viewing angles are poor and you have to sit straight in front to enjoy an accurate image. Motion handling is excellent with a fast response time that helps display crisp motion with minimal blur trail. The input lag is very low, and the TV supports FreeSync variable refresh rate technology to please gamers.

Pros
  • Excellent motion handling.
  • Low input lag, great for gaming.
Cons
  • Image loses accuracy when viewed at an angle.
  • Can't get bright in HDR.

Market Context

What it is: This model's position in the TV market; how it compares to other TVs.

The Samsung RU8000 is a 2019 mid-range UHD TV. It is the replacement of the NU8000 in Samsung's lineup. It has similar advanced features found on the higher-end QLEDs like the Samsung Q60R or the Q70R. Its direct competitors are other mid-range LED TVs like the Sony X900F, the LG SK9500, or the Vizio P Series Quantum 2019.

8.5

Design

Score components: Subjectively assigned
Curved : No

The Samsung RU8000 has an excellent design. The stand is made of good quality plastic, supports the TV well, and prevents most wobbling. The back of the TV is plain with a nice texture and resembles the back of the Q60R. The TV is relatively thin and its borders are similar to the Q60R. The build quality is decent, and although we noticed a small crack in the lower left corner of the bezel (which did not affect our tests in any way), you should have no issues with the TV's build quality.

Stand

The stand is made of good quality plastic and supports the TV well. It's similar to the Samsung Q80R's stand, but the legs are not hollow to serve as cable guides. The TV wobbles a little if nudged, but it's nothing serious.

Footprint of the 55" TV stand: 35.0" x 9.3"

Back
Wall Mount : VESA 200x200

The back of the TV is almost identical to the Q80R, the Q70R, and the Q60R. It's made of plastic and has the typical Samsung textured pattern. There are a few grooves at the bottom that can guide the cables to the legs where a clip helps with the cable management.

Note: We only have one clip, which is unusual, but we're not sure if there were two in the box and we just lost the other one.

Borders
Borders : 0.55" (1.4 cm)

The borders are thin and not very noticeable. They are, however, slightly thicker than last year's NU8000, and in the same ballpark as this year's Q60R. We noticed that the lower left corner of the bezel was cracked, but it did not interfere with our testing.

Thickness
Max Thickness : 2.37" (6.0 cm)

The TV is slightly thinner than this year's Q60R, the Q70R, and the Q80R, but slightly thicker than the RU7100. If you decide to wall mount it, you must use the spacers that are included in the box because of the TV's curved back. It won't stick out much.

Temperature
What it is: It is the average and maximum operating temperatures we measured on the TV. If there is an external device, like a One Connect box in some Samsungs, we measure the temperature of that as well.
When it matters: If the temperature of your TV is much higher, check that nothing is blocking the vents.
Maximum Temperature
What it is: The peak temperature found on the TV.
When it matters: If the TV is placed in an enclosed space.
Good value: <35°C
Noticeable difference: 5°C

6.5 Build Quality
What it is: It represents our perception of the quality of the construction of the TV, of the materials used, and how they all blend.
When it matters: Poor build quality might lessen the expected lifetime of the TV, or make it more prone to faults due to mishandling.
Score components: Subjectively assigned

The build quality is decent. It's very similar to the RU7100 and the Q60R. We did notice a crack in the lower left corner of the bezel, which didn't interfere with our testing. The TV feels robust and sturdy and you should have no issues with it.

7.5

Picture Quality

The picture quality is good. The TV can produce deep uniform blacks in a dark room thanks to the high native contrast ratio and excellent black uniformity. Unfortunately, it does not support a local dimming feature to further improve dark room performance. It can get reasonably bright in SDR, good for an average-lit room, and can handle reflections well so you do not have to worry if your room has a few light sources. It has a wide color gamut, but it can't get very bright in HDR, so small highlights in certain scenes don't stand out as they should. The RU8000 has good gray uniformity with minimal dirty screen effect that will satisfy even demanding sports fans, but the viewing angles are poor and the image deteriorates rapidly when viewed from the side. This doesn't make it a good choice if you often watch games with a large group of friends.

9.0 Contrast
What it is: Brightness difference between white and black. This is the main component of picture quality.
When it matters: Always, but especially when watching dark scenes.

This TV has very good peak brightness. However, it is not as bright as last year's NU8000, but in the same ballpark as the Q60R. It's suitable for rooms that aren't very bright. The RU8000 has pretty consistent brightness regardless of the content it displays, except for the 2% window which is dimmed by the TV's CE (Frame) Dimming feature.

We measured the peak brightness after calibration, using the 'Movie' Picture Mode and 'Warm 2' Color Tone, with Gamma set to '2.2'. We use these settings because they give the most accurate image, and this is the maximum brightness that you can get with these settings.

If you do not care about image accuracy, you can obtain higher brightness levels. We were able to reach 396 nits on the 'Movie' Picture Mode and 'Warm 1' Color Tone. Other picture modes were not brighter, which is unexpected.

The HDR peak brightness of the RU8000 is mediocre. It's less bright than the NU8000 and has about the same peak brightness as the Q60R. The TV can't display HDR highlights as bright as they should be.

We measured the peak brightness before calibration, using the 'Movie' Picture Mode and 'Warm 2' Color Tone. We use these settings because they give the most accurate image, and this is the maximum brightness that you can get with these settings.

If you do not care about image accuracy, you can obtain slightly higher brightness levels. For this TV, however, we were only able to reach a brightness level of 365 nits ('Movie' Picture Mode and 'Warm 1' Color Tone), which is not much brighter than our accurate image brightness.

This TV has good gray uniformity. The edges of the screen are slightly darker, but the center is pretty uniform and very little dirty screen effect can be seen, which is great news for sports fans. The uniformity of darker scenes is very good. The corners and the edges appear slightly brighter than the center, but it is hardly noticeable in normal content. This is better behavior than the Q60R and in the same ballpark as last year's NU8000.

This TV has poor viewing angles, as expected from a VA panel TV. Even at small angles off-center, gamma shifts and black levels rise, and the image loses accuracy and looks washed out. This is not a good TV if you'll be watching from the side. If viewing angles are an issue, then check out an IPS TV like the LG SK9000.

The reflection handling of the RU8000 is good. The TV handles reflections almost identically to last year's NU8000. You shouldn't have any issues with reflections in most situations. However, if you place the TV in a room with many bright windows, the reflections combined with the TV's low peak brightness might make it hard to see a clear image.

The RU8000 can display a wide color gamut. Its gamut is not as wide as the Q60R, the entry-level QLED, and it also falls a little short of last year's NU8000.

The 'Movie' EOTF (shown above) follows the input stimulus well until it smoothly starts to roll off near the TV's peak brightness. In 'Game' mode, the EOTF doesn't follow the stimulus closely and thus HDR gaming is slightly dimmer as shown here.

If you find HDR too dim, check out our recommendations here. With these settings, the RU8000 is noticeably brighter in HDR, as shown in this EOTF.

The RU8000 has good gradient banding. Some fine banding is visible in the dark greens and reds, but it's nothing too serious and certainly hard to notice in normal content. If, however, you find that banding is bothering you, set the Digital Clean View to 'Auto' to remove most of it. Unfortunately, this can also cause some loss of fine detail in certain scenes.

When it matters: It can help explain some display behaviors and can provide an indication of whether two panels are the same or not.
8.7

Motion

The motion handling of the Samsung RU8000 is excellent. The TV has a very fast response time which is great for watching sports and playing video games. It uses PWM dimming to dim its backlight, and the flicker might bother some flicker-sensitive people. On the upside, the RU8000 has an optional black frame insertion feature that can help make the image crisper and supports motion interpolation to please the soap opera effect fans. The TV also supports FreeSync variable refresh rate for a nearly tear-free gaming experience.

The response time is excellent and an improvement over last year's NU8000. It is great for fast-moving content like sports and video games. There is some small overshoot in the 0-20% transition, which can cause some haloing in really dark scenes, but it shouldn't be very noticeable. Unfortunately, there are noticeable duplications due to the backlight flicker.

6.0 Flicker-Free
What it is: How noticeable flicker is on 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.
:
240 Hz

The RU8000 uses Pulse Width Modulation to dim its backlight. The flicker frequency is 240Hz in 'Movie' mode but drops to 120Hz in all other modes. It also drops to 120Hz in the 'Movie' mode if you set Auto Motion Plus to either 'Custom' or 'Auto'. This is very similar what we have seen here on last year's Q6FN.

10 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
:
60 Hz

The Samsung RU8000 has a black frame insertion feature that can lower the flicker frequency to 60Hz. This can help make the image crisper. Unfortunately, this decreases the picture brightness, and 60Hz flicker can be bothersome to some people.

Enabling Auto Motion Plus automatically sets the flicker to 120Hz and enabling LED Clear Motion further reduces the flicker frequency to 60Hz.

When 'Game' mode is enabled, the flicker frequency is always 120Hz, but if you enable LED Clear Motion in Game Motion Plus, the flicker frequency changes to 60Hz and makes the image even crisper.

10 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.
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.
:
Yes

The RU8000 can interpolate lower frame rate content up to 120fps. To enable motion interpolation, you must enable Auto Motion Plus and adjust the available sliders.

See here for more information regarding the settings that control the RU8000's motion interpolation feature.

Note that just setting Auto Motion Plus to 'Custom' changes the backlight flicker to 120Hz.

The 49" model has a 60Hz panel and can only interpolate content to 60fps.

What it is: The inputs which support a variable refresh rate (eg. HDMI, DisplayPort)
When it matters: When gaming with different consoles or graphics cards.
:
HDMI

The Samsung RU8000 has a native refresh rate of 120Hz. It supports the FreeSync variable refresh rate technology for a nearly tear-free gaming experience for those with a compatible AMD card or an Xbox One. The VRR range is excellent and it is the same at 1080p and at 1440p. At 4k, however, the range is narrower, as the TV only supports resolutions up to 4k @ 60Hz.

Unfortunately, NVIDIA's current Adaptive Sync drivers are not currently compatible with this TV. FreeSync from NVIDIA graphics cards currently works only over DisplayPort, and the RU8000 does not have such a port.

We tested the TV on 'Game' mode, without interpolation or any other gaming processing setting, and we set FreeSync to 'Ultimate' to obtain the widest possible range.

If FreeSync is enabled on a connected device, auto game mode doesn't work at all; it will always stay in game mode.

Note that the 49" model has a 60Hz panel and doesn't support FreeSync.

Auto Low Latency Mode (ALLM)
What it is: Whether a source (such as a game console) can request the TV switch into a low latency mode (such as game mode).
When it matters: Console gaming; both PS4 and Xbox One S/X support ALLM.
:
Yes

The RU8000 has an excellent low input lag, great for gaming. The input lag is only slightly higher than the input lag of the 2019 QLEDs and a little lower than the NU8000. To get the lowest input lag, you must set the TV to 'Game Mode.' However, when in 'PC Mode,' you get the same low input lag without having to set the TV to 'Game' mode. To display proper chroma 4:4:4 you must set the TV to 'PC mode.'

Note: When the TV was set to 'PC mode' or 'Game Mode' and we sent a 120Hz signal, the TV skipped every second frame, just like the Q70R and the Q80R. Therefore, in order to measure the input lag of a proper 120Hz video, like in the case of the 1080p @ 120Hz and the 1440p @ 120Hz, we set the TV to 'Movie' mode. However, when a true VRR 120Hz signal was sent in fullscreen exclusive mode, there was no frame skipping and the video displayed properly, so we measured the VRR input lag using 'Game Mode' as normal.

When motion interpolation is enabled in 'Game Mode' through the Game Motion Plus menu, the input lag is 38.6ms when you interpolate to 60fps and 39.9ms for 120fps.

To find out more about what settings to use to obtain those numbers, and about the Auto Low Latency Mode, see our recommended settings for Gaming.

The RU8000, just like the Q70R, the Q80R, and the Q90R, supports most common resolutions, including 1440p @ 60Hz, which isn't supported on the 2018 NU8000. You must set the TV to 'PC Mode' to display proper chroma 4:4:4. Unfortunately, the TV, just like other 2019 Samsungs, skips frames when sent 120Hz in 'PC Mode' or 'Game Mode,' so you cannot have proper 120Hz and proper 4:4:4 simultaneously.

The 49" model has a 60Hz panel, and does not support 120Hz inputs.

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 on the Samsung RU8000 is decent and nearly identical to the NU8000. It gets reasonably loud, but may not be loud enough for busy environments. It doesn't have deep bass and won't produce any thump or rumble, but it will deliver clear and intelligible dialog. For a better sound, it's recommended to add dedicated speakers or a soundbar.

The frequency response is decent. LFE (low-frequency extension) is at 80Hz, which is okay. This means the RU8000 has a decent amount of punch to its bass but can't produce any thump or rumble. The response above the LFE is fairly flat and well-balanced, and the TV produces clear and intelligible dialog. The RU8000 doesn't have a room correction system and can get reasonably loud, but not loud enough for large and noisy environments.

The RU8000 is a mid-range TV, but there are better TVs for the same price. See our recommendations for the best TVs, the best HDR gaming TVs, and the best smart TVs.

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

The Samsung NU8000 is a bit better than the Samsung RU8000. The NU8000 also has a local dimming feature that can improve dark room performance. The NU8000 has better SDR peak brightness and is more suitable if you have a bright room. The NU8000 can also get brighter in HDR and has a better color volume, which is great for HDR content. The RU8000, on the other hand, has a lower input lag, good for gaming, and a faster response time, great for watching sports.

Samsung RU7100
43" 50" 55" 58" 65" 75"

The Samsung RU8000 is better than the Samsung RU7100. The Samsung RU8000 can get brighter and has better reflection handling, so it's more suitable if you have a bright room. It can display judder-free movies and has a faster response time that delivers crisper motion. Finally, the RU8000 has support for the FreeSync variable refresh rate technology, which is great for demanding gamers.

Samsung Q60/Q60R QLED
43" 49" 55" 65" 75" 82"

The Samsung Q60/Q60R QLED and the Samsung RU8000 both have very similar performance. The RU8000 has better black uniformity that helps deliver more uniform blacks in a dark room, and a bit better gray uniformity, which is great if you're a sports fan.

Sony X900F
49" 55" 65" 75" 85"

The Sony X900F is better than the Samsung RU8000. The Sony X900F has a local dimming feature that significantly improves dark room performance. The Sony can get brighter and can handle reflections a little better, so it's more suitable if you have a bright room. The X900F can deliver better HDR performance thanks to the wider color gamut and better HDR peak brightness. The Samsung RU8000, on the other hand, is a better TV for gaming, thanks to the lower input lag and the support for FreeSync VRR.

Samsung Q70/Q70R QLED
49" 55" 65" 75" 82" 85"

The Samsung Q70/Q70R QLED TV is much better than the Samsung RU8000. The Q70R features a full array local dimming feature, which improves dark-room viewing. The Q70 is also a lot brighter, especially with HDR content.

LG B8 OLED
55" 65"

These are two different types of TVs, each with advantages and disadvantages. The LG B8 is an OLED that can display perfect blacks and delivers a better dark room performance. The viewing angles on the B8 are wider, and fast-moving content has almost no blur thanks to the faster response time. The Samsung RU8000, on the other hand, can get brighter, which is great for bright rooms, and it's packed with gaming features, like FreeSync support, that will please demanding gamers.

Samsung Q6FN/Q6/Q6F QLED 2018
49" 55" 65" 75" 82"

The Samsung Q6FN is a bit better than the Samsung RU8000. The Q6FN has an edge-lit local dimming feature, which, although it isn't very effective, it can help a bit with some content. The Q6FN can also get a lot brighter, especially with HDR content.

TCL 6 Series/R617 2018
55" 65" 75"

The TCL R617 is slightly better than the Samsung RU8000. The R617 has a full array local dimming feature, although it is mediocre, and the R617 can get a lot brighter. The Samsung RU8000, on the other hand, has better uniformity and a faster response time, so fast-moving objects in games and movies look better.

LG SM8600
49" 55" 65" 75"

The Samsung RU8000 and the LG SM8600 use different technologies, each with their own strengths and weaknesses. The RU8000 is better suited for viewing in a dark room, sitting directly in front of it. The LG SM8600 is better suited for a brighter room, and the wide viewing angle is better for side seating. Beyond these differences, the RU8000 is brighter, but has worse reflection handling.

LG SK9000
55" 65"

The two TVs have different panel technologies, each with their advantages and disadvantages. If you have a room with a wide seating arrangement, the LG SK9000 is a better choice as the image remains accurate when you watch from the side. On the other hand, if you sit straight in front and dark room performance is essential, then you'll appreciate the deep uniform blacks the Samsung RU8000 can offer. The RU8000 also has a bit better gray uniformity and faster response time, which are great if you're a sports fan. The SK9000 can handle reflections a little better, which is good if your room has many lights; it also has a local dimming feature to improve its dark room performance.
