Samsung RU8000 TV Review

The Samsung RU8000 is a 2019 mid-range UHD TV. It replaces the Samsung NU8000 in Samsung's lineup, and it has similar advanced features to those found on the higher-end QLEDs like the Samsung Q60/Q60R QLED or the Samsung Q70/Q70R QLED. Its direct competitors are other mid-range LED TVs like the Sony X900F, the LG SK9500, or the Vizio P Series Quantum 2019.

The Samsung RU8000 has an excellent design. The stand is made of high-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 Samsung Q60/Q60R QLED.

The stand is made of good quality plastic and supports the TV well. It's similar to the Samsung Q80/Q80R QLED'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 inch TV stand: 35.0" x 9.3"

The back of the TV is almost identical to the Samsung Q80/Q80R QLED and other QLEDs from Samsung's 2019 lineup. 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.

The borders are thin and not very noticeable. They are, however, slightly thicker than its predecessor, the Samsung NU8000. We noticed that the lower left corner of the bezel on our unit was cracked, but it did not interfere with our testing.

The TV is slightly thinner than the 2019 QLEDs, but slightly thicker than the Samsung 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 shouldn't stick out much.

The build quality feels okay. We did notice a crack in the lower left corner of the bezel, but it didn't interfere with our testing. The TV feels fairly sturdy and you should have no issues with it.

This TV has a fantastic native contrast ratio. It can deliver deep blacks in a dark room, which is great for watching movies. Unfortunately, there's no local dimming to further improve black levels.

There's no local dimming feature on this TV. The video above is provided for reference only.

Decent SDR peak brightness. It remains fairly consistent when displaying different types of content, except the Peak 2% Window, which is noticeably less bright. This affects the way bright highlights appear across the screen. Overall, the Samsung RU8000 can get bright enough to combat glare in most average-lit rooms.

We measured the peak brightness after calibration, using the 'Movie' Picture Mode and 'Warm 2' Color Tone, with Gamma set to '2.2'.

If you don't care about image accuracy, you can obtain higher brightness levels by adjusting the settings. We were able to reach 396 nits using the 'Movie' Picture Mode and 'Warm 1' Color Tone.

The HDR brightness is sub-par. As with SDR, it remains fairly consistent across different types of content but gets less bright when small highlights flash across the screen. All picture modes and color temperatures had the same max peak brightness.

We measured the peak brightness before calibration, using the 'Movie' Picture Mode and 'Warm 2' Color Tone.

If you don't care as much 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, using 'Movie' Picture Mode and 'Warm 1' Color Tone, which isn't much brighter than our accurate image brightness.

Good gray uniformity. The edges of the screen are a bit darker, but the rest is fairly uniform, which is good for when there are uniform colors across the screen. Most people shouldn't notice any dirty screen effect, which can be distracting during sports.

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

Amazing black uniformity. There's a bit of clouding throughout, and even more so on the right, but it shouldn't be noticeable for most people. This is a good TV if you're watching dark scenes in a dark room.

The Samsung RU8000 has decent reflection handling. Its semi-gloss finish is good with indirect reflections, but it struggles with direct light, so it's best to avoid placing it directly across from bright lighting. If you're looking for a TV with fantastic reflection handling, then check out the Samsung Q90/Q90R QLED.

The Samsung RU8000 has decent out-of-the-box color accuracy. There are inaccuracies that people might notice in shades of gray and in some colors like blue and magenta. The gamma doesn't follow the curve well, and most scenes look a little brighter. The color temperature is a little warmer than the target of 6500K. If you want a similar TV with better color accuracy, check out the Samsung Q60/Q60T QLED.

After calibration, the accuracy is fantastic. The white balance is nearly perfect, and the colors are also greatly improved, but some people might still spot a few inaccuracies in the dark blue and the dark red. The gamma follows the curve very well and the color temperature is almost spot on the 6500K target.

You can see our recommended settings here.

There are no obvious issues or artifacts when upscaling low-quality content like DVDs.

720p, like content from a cable box, is upscaled well.

1080p content, like Blu-rays, is displayed almost as well as native 4k content.

There are no issues with 4k content.

The Samsung RU8000 can't display an 8k signal.

This TV uses a BGR subpixel layout, which can affect how text is rendered. You can read more about that here.

The Samsung RU8000 has a good color gamut, considered wide for HDR content.

The EOTF follows the target quite closely until it rolls off towards the TV's peak brightness, so most scenes overall appear as bright as they should but brighter highlights don't quite pop as intended. In 'Game' mode, the EOTF doesn't follow the stimulus closely, so HDR gaming is slightly dimmer as you can see 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 color volume on this TV is okay. It can display most dark colors, but like most LED TVs, it has trouble with bright blues. The Samsung NU8000 has a better color volume.

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

There's some very faint image retention immediately after the long exposure of our test image, but it goes away very fast and is hardly noticeable in normal content.

We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.

The Samsung RU8000 has an impressive response time, resulting in smooth motion in fast-moving content like video games or sports. There's a bit of overshoot in the 0-20% transition, though, so you may notice some motion artifacts in dark scenes.

The Samsung 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 to what we have seen here on the Samsung Q6FN/Q6/Q6F QLED 2018.

This TV has a Black Frame Insertion feature to help reduce motion blur and make fast-moving objects appear clearer. The BFI feature can lower the flicker frequency to 60Hz. Note that the BFI score is based on the minimum and maximum frequency at which it can operate, not how well it actually performs.

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

In 'Game' mode, the flicker frequency is always 120Hz. Once again, enabling LED Clear Motion with Game Motion Plus reduces the frequency to 60Hz, making motion look clearer.

The Samsung 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 Samsung RU8000's motion interpolation feature.

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

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

The Samsung RU8000's fast response time makes the image appear to stutter in movies or other lower frame rate content. If stutter bothers you, motion interpolation or the optional Black Frame Insertion feature can help.

This TV can remove judder from all sources.

See our recommended settings on how to remove judder here.

Update 12/17/2019: A flaw was discovered in the way we were testing for G-SYNC compatibility with TVs. We've corrected the flaw, and have retested the 2019 Samsung and LG TVs, and found that the Samsung RU8000 doesn't work properly with NVIDIA's current Adaptive Sync drivers.

The Samsung RU8000 has a native refresh rate of 120Hz. It supports 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's the same at 1080p and at 1440p. At 4k, however, the range is narrower, as the TV only supports resolutions up to 60Hz.

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, as the TV simply stays in 'Game' mode.

Note: The 49 inch model has a 60Hz panel and doesn't support FreeSync.
