The Samsung DU8000 is an entry-level model in Samsung's 2024 lineup and replaces the Samsung CU8000. It sits above the Samsung DU7000 and below Samsung's QLED lineup. It uses Samsung's AirSlim design, which is meant to provide a slim design that blends into your wall, and this TV comes with Samsung's proprietary Tizen OS, which has been updated to version 8.0 in 2024. The TV has a 20W 2.0 channel speaker system built in and is available in a wide variety of sizes: anything from a small 43-inch model to a large 85-inch model. It's a basic TV but has some optional features like Motion Xcelerator to help smooth out motion and the Mega Contrast feature, designed to automatically adjust the brightness and contrast of the image.
Our Verdict
The Samsung DU8000 is poor for mixed usage. It looks pretty bad in a dark room due to its poor black levels, but it's also not nearly bright enough to handle glare in a well-lit room. HDR content is lackluster due to the TV's muted colors and bad HDR brightness. This model also doesn't perform well for gamers, since it doesn't have the modern gaming features needed to take advantage of today's consoles. It even has a narrow viewing angle, making it unsuitable for wide seating arrangements.
Not nearly bright enough in SDR to overcome glare in bright rooms.
Way too dim in HDR for highlights to stand out.
Poor contrast and no local dimming means blacks look grayish.
Doesn't support modern gaming features like HDMI 2.1, 120Hz, and VRR.
Direct reflections are very visible.
The Samsung DU8000 is inadequate for a home theater. The TV has poor black levels, so blacks look gray during most scenes, making it look unimpressive in dark rooms. The TV is way too dim in HDR for highlights to stand out at all, and its inadequate HDR color volume leads to colors looking dull and unimpressive. It does a decent job upscaling low-resolution content, but low-bitrate content is still full of artifacts due to the TV's poor low-quality content smoothing.
Way too dim in HDR for highlights to stand out.
Poor contrast and no local dimming means blacks look grayish.
Dark colors in HDR lack depth, and bright colors are dim.
Poor low-quality content smoothing leads to distracting artifacts in low-bitrate content.
No Dolby Vision HDR or DTS Audio support.
The Samsung DU8000 is sub-par for a bright room. The TV's image quality remains mostly unaffected by ambient lighting, so blacks and colors don't look much different from what they do in a dark room. However, the TV is just too dim to fight glare in any environment other than a dimly lit room, so it's unsuitable for a bright room. Even in a dimly lit room, mirror-like reflections are visible on screen, so don't place any light sources directly opposite the screen.
Black levels and colors are barely affected by ambient lighting.
Not nearly bright enough in SDR to overcome glare in bright rooms.
Direct reflections are very visible.
The Samsung DU8000 is a poor TV for watching sports. It's too dim to handle glare in even moderately lit rooms, so it's really only suitable for dimly lit environments. The TV does a poor job cleaning up artifacts in low-quality content, so cable feeds look noisy. On the other hand, it has decent upscaling, so low-resolution feeds still have some details intact. Sadly, fast motion is blurry, colors are a bit muted, and there's some dirty screen effect towards the center of the screen, so the image is far from pristine. Furthermore, the TV has a pretty narrow viewing angle, so its image quality degrades quickly when the screen is viewed from an angle.
Not nearly bright enough in SDR to overcome glare in bright rooms.
Direct reflections are very visible.
Poor low-quality content smoothing leads to distracting artifacts in low-bitrate content.
Noticeable dirty screen effect and uneven brightness due to its unremarkable gray uniformity.
The Samsung DU8000 is a poor gaming TV. It lacks modern gaming features, so you're limited to 4k @ 60Hz. It also doesn't support VRR, so there's some screen tearing when your frame rate is inconsistent. The TV's image quality isn't nearly good enough to make games look as good as they should, since the TV's black levels, brightness, and colors are all very underwhelming.
Low input lag at 60Hz.
Way too dim in HDR for highlights to stand out.
Poor contrast and no local dimming means blacks look grayish.
Dark colors in HDR lack depth, and bright colors are dim.
Slow pixel transitions in Game Mode leads to blurry motion.
Doesn't support modern gaming features like HDMI 2.1, 120Hz, and VRR.
The Samsung DU8000 has bad brightness. It's too dim in SDR to handle glare in anything other than a dimly lit room. HDR content looks dim and lacks pop, since the TV doesn't have close to the brightness needed to make highlights stand out. Overall, this is a very dim model.
Not nearly bright enough in SDR to overcome glare in bright rooms.
Way too dim in HDR for highlights to stand out.
The Samsung DU8000 has poor black levels. The TV has great black uniformity, so blacks are mostly uniform across the screen during dark scenes. However, the TV's contrast is so poor that blacks look gray in the vast majority of scenes, so the image looks washed out most of the time.
Great black uniformity.
Poor contrast and no local dimming means blacks look grayish.
The Samsung DU8000 has middling colors. The TV's color volume in SDR and HDR isn't up to par, so colors look muted, dim, and lack richness. Its out-of-the-box color accuracy is decent in SDR, so colors don't stray too far from what they should look like. However, the TV is very inaccurate in HDR, and everything looks much colder than intended by the content creator.
Dark colors in HDR lack depth, and bright colors are dim.
Poor color accuracy in HDR.
Note: We're in the process of improving our tests related to image processing, but this score should give you a general idea of how a TV performs overall with its image processing capabilities.
The Samsung DU8000 has unremarkable image processing. Its upscaling is decent, so you don't have to look at an overly soft image when watching low-resolution content, but it still lacks some details. Unfortunately, the TV's low-quality content smoothing is poor, so low-bitrate content has visible artifacts. The TV's gradient handling is alright, so even though there's some apparent banding in green gradients, other colors aren't too distracting. Finally, it does a mediocre job of displaying HDR content at the brightness level intended by the filmmaker, since blacks are raised, and the rest of the image is a bit too dim.
Poor low-quality content smoothing leads to distracting artifacts in low-bitrate content.
The Samsung DU8000 has sub-par responsiveness in its dedicated gaming mode. The TV lacks modern features found on many other models, so you're limited to 4k @ 60Hz, and it doesn't support VRR, so you see some screen tearing. Its input lag is low enough that gaming feels responsive, but you miss out on the lower input lag provided by higher refresh rates. Pixel response times are mediocre, so fast motion has blur trails behind it. Overall, this isn't a good choice if you care about gaming performance.
Low input lag at 60Hz.
Slow pixel transitions in Game Mode leads to blurry motion.
Doesn't support modern gaming features like HDMI 2.1, 120Hz, and VRR.
We're in the process of fixing the way we evaluate a TV's overall motion handling. This section is currently broken, and the score isn't indicative of how well a TV handles motion overall.

Differences Between Sizes And Variants
We bought and tested the 65-inch Samsung DU8000, but our results are also valid for the 43-inch, 50-inch, 55-inch, and 75-inch models. The 85-inch DU8000 uses a 120Hz panel and supports VRR. Note that the last four letters in the model number (FXZA in this case) vary between retailers and individual regions, but there's no difference in performance.
There's also a minor variant of this TV known as the Samsung DUX1E. It's an online exclusive that's only available in a 43-inch and 50-inch size. There's no difference in performance, but the stand and bezel are dark gray instead of black.

Popular TV Comparisons
The Samsung DU8000 is an okay TV overall, but it's held back by its lack of local dimming, low peak brightness, narrow viewing angle, and lack of modern gaming features. You can do much better with your money by going with a TV like the Hisense U65QF or the TCL QM6K, both of which have much better overall picture quality, more features like local dimming, and HDMI 2.1 bandwidth for gamers.
It's also important to note that we encountered a bug that negatively affected our initial HDR test results. We don't know how common this issue is, but it's certainly worth mentioning.
For more options, check out our recommendations for the best budget TVs, the best TVs under $1,000, and the best 4k TVs.
The Samsung U8000F offers an updated design over its predecessor, the Samsung DU8000, but otherwise performs nearly the same. The U8000F is a bit brighter and more accurate out of the box, but the differences are minor. The U8000F also adds VRR support to reduce tearing, but since its effective refresh rate range is so narrow, this feature isn't very useful most of the time.
The Samsung Q7F 2025 is a bit better than the Samsung DU8000, but not by much. The Q7F is a bit brighter in HDR and SDR and has deeper contrast, even if neither set has local dimming. It's also a bit more colorful and is more accurate in SDR out of the box. Ultimately, these are basic TVs, and while the Q7F is a bit better overall, it's not worth paying much more for it than you would for the DU8000.
The Samsung DU8000 and the Samsung DU7200 are very similar overall. The DU7200 has an edge with contrast, displaying slightly deeper blacks. The DU7200 is also brighter overall, meaning it fights a bit more glare in a bright room and displays brighter highlights in HDR. On the other hand, the DU8000 displays a wider range of colors, so you get a slightly more vibrant image on it.
The Samsung Q60D is better overall than the Samsung DU8000. The Q60D has superior contrast for deeper blacks, overcomes more glare in a bright room thanks to its much higher SDR peak brightness, and provides a more impactful HDR experience due to its much better HDR brightness. Additionally, the Q60D displays a wider range of colors and does a slightly better job of upscaling low-resolution content. On the other hand, the DU8000 has a faster response time, so it displays fast motion with less blur behind it.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests are done with specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.

If you want a Samsung TV that's better suited for a bright room, check out the Samsung Q60D or the Samsung DU6900.
The Samsung DU8000 has poor contrast. Its native contrast is okay, but it lacks a local dimming feature, so blacks are deep in dim and dark scenes, but they become raised and washed out when bright highlights are on the screen. It still looks much better than many similar budget models, like the Hisense A6N.
The Samsung DU8000 doesn't have a local dimming feature, so there's no haloing around bright objects or subtitles during dark scenes.
This TV doesn't have a local dimming feature, so it can't adjust the backlight of individual zones to brighten up highlights without impacting the rest of the image. This means that there's no distracting flicker or brightness changes as bright highlights move between dimming zones.
Switching to Game Mode doesn't result in any noticeable difference in dark scene performance.
The TV's black uniformity is great, although there's some minor cloudiness throughout, and there's no local dimming to further improve it.
The Samsung DU8000 has unremarkable SDR color volume. Like almost any modern TV, it covers the entirety of the commonly used BT.709 color space. Unfortunately, the TV has mediocre coverage of the DCI-P3 color space and poor coverage of the widest BT.2020 color space, so this isn't a good model if you like to force SDR content into a wide color space for increased saturation.
| Volume ΔE³ | DCI-P3 Coverage |
BT.2020 Coverage |
|---|---|---|
| L10 | 82.44% | 61.32% |
| L20 | 83.63% | 61.03% |
| L30 | 82.01% | 59.94% |
| L40 | 80.82% | 60.52% |
| L50 | 80.34% | 59.99% |
| L60 | 78.17% | 56.79% |
| L70 | 74.31% | 47.89% |
| L80 | 73.13% | 45.09% |
| L90 | 73.08% | 45.44% |
| L100 | 79.50% | 57.23% |
| Total | 77.38% | 53.33% |
The TV's HDR color volume is inadequate. It doesn't display darker colors well due to its unremarkable contrast, and it can't display most colors at high luminance levels.
The Samsung DU8000 has decent pre-calibration accuracy. Reds, greens, and blues are underrepresented in darker shades of gray, color temperature is cooler than our target of 6500K, and gamma is much darker than the 2.2 target. Color accuracy is decent overall, but there are noticeable inaccuracies with magentas, reds, and blues.
The Samsung DU8000 has good post-calibration accuracy, but unfortunately, calibrating the TV doesn't do much to affect the picture. Using the 2-point offset and 20-point settings has no effect at all, so you're limited to using the 2-point gain setting only. This is unusual and a bug that Samsung is aware of, but it currently really limits your calibration options.
Reds, greens, and blues are still underrepresented in darker shades of gray, and although the color temperature is a little closer to our 6500K target, it's still too cool. Colors are slightly more accurate, but there are still noticeable inaccuracies with magentas, reds, and blues. Gamma barely changed at all, so everything is still too dark.
See our full calibration settings.
The TV has poor HDR color accuracy before calibration. There's way too much blue in most shades of gray, while reds are underrepresented, which makes the TV's color temperature significantly bluer than the industry standard 6500K. The overall color accuracy is unremarkable, with noticeable mapping errors in most colors.
The TV has great HDR color accuracy after calibration. Its white balance is much better, and the TV's color temperature is now almost exactly at 6500K. Unfortunately, the TV's overall color accuracy is only decent, so this model isn't a good choice if you want accurate colors.
The Samsung DU8000 has unremarkable PQ EOTF tracking. Blacks and near-blacks are slightly raised, while shadows and midtones are displayed a bit dimmer than intended. There's only a slight roll-off with content mastered at 600 and 1,000 nits, so most details in bright highlights are lost. With content mastered at 4,000 nits, there's a more gradual roll-off to retain some detail in highlights.
By changing HDR Tone Mapping to 'Active,' you get a brighter overall image but a less accurate one. It also changes the behavior of the tone mapping depending on the picture setting used. In 'Movie' mode, there's a more gradual roll-off near the TV's peak brightness to preserve more details in highlights. In 'Game' mode, the TV has a sharp cut-off, so it stays brighter near the TV's peak brightness, but details in bright highlights are lost. You can see the results below.
The TV has poor low-quality content smoothing. Although it preserves details well, there's no noticeable smoothing done, and artifacts are still present. There's likely a bug at play here since last year's Samsung CU8000 did a much better job at removing artifacts.
The TV's upscaling and sharpness processing is satisfactory overall. Fine details are upscaled well for the most part, but hardcoded text is a bit hard to make out. Adjusting the sharpness value from '0' to '20' has very little effect on the image, but the following setting is the most accurate without adding oversharpening:
- Sharpness: 5
The TV's gradient handling is alright. There's significant banding in greens and noticeable banding in dark grays and dark reds.
The TV has low input lag when used in Game Mode. To have low input lag while transmitting a chroma 4:4:4 signal, you need to set the input to 'PC' and enable Game Mode.
Unfortunately, 1440p @ 60Hz doesn't work while in Game Mode, so the 1440p @ 60Hz results are with the TV set to 'Movie,' which leads to a lot more input lag.
The TV supports all common resolutions at 60Hz. Unfortunately, 1440p doesn't work in Game Mode. The TV displays a cropped window, even though 1440p works fine outside of Game Mode.
There's also an intermittent issue when displaying chroma 4:4:4 that resembles dithering.
This TV doesn't support any variable refresh rate technologies. The 85-inch model of the Samsung DU8000 does support VRR alongside a native refresh rate of 120Hz. If you want a smaller TV that supports VRR, check out the Samsung Q70D.
The TV's CAD at its maximum refresh rate of 60Hz is mediocre. There's some overshoot with certain transitions, which leads to inverse ghosting. It's also slower when leaving and entering a dark state, leading to some black smearing.
This TV doesn't support a 120Hz refresh rate.
The TV's CAD at its maximum refresh rate of 60Hz is mediocre. There's some overshoot with certain transitions, which leads to inverse ghosting. It's also slower when leaving and entering a dark state, leading to some black smearing.
The Samsung DU8000 is a 60Hz TV, so it only supports 4k @ 60Hz on the P55. It has Auto Low Latency Mode, so it'll automatically switch to Game Mode when the TV detects a game console as its input device, which gives you the lowest possible input lag for games. Unfortunately, the TV doesn't display 1440p properly inside of Game Mode, so you can't game in 1440p with the lowest input lag possible.
The 85-inch variant of this TV supports 4k @ 120Hz, as well as VRR.
The Samsung DU8000 is a 60Hz TV, so it only supports 4k @ 60Hz on the Xbox Series X|S. It has Auto Low Latency Mode, so it'll automatically switch to Game Mode when the TV detects a game console as its input device, which gives you the lowest possible input lag for games. Unfortunately, the TV doesn't display 1440p properly inside of Game Mode, so you can't game in 1440p with the lowest input lag possible.
The 85-inch variant of this TV supports 4k @ 120Hz, as well as VRR.
Due to this TV's relatively slow response time, it does an alright job with stutter in 24 fps content like movies, but there's still noticeable stutter with slower camera movements. It's fantastic with 60 fps content, though, so there isn't noticeable stutter with higher frame rate content.
The Samsung DU8000 removes judder from native 24p signals, like DVD or Blu-ray players, as well as from native apps. Unfortunately, it doesn't remove judder from 60i or 60p sources, so movies played from satellite/cable boxes aren't judder-free.
The Samsung DU8000 has an okay response time when watching content. Most motion is clear, but there's still some noticeable blur behind very quick-moving objects. Furthermore, transitions in dark scenes are very slow, which results in black smearing behind dark objects.
The TV uses pulse-width modulation (PWM) to dim its backlight, which introduces flicker that can bother people who are sensitive to it. The amount of flicker varies depending on what picture mode the TV is set to and what settings you're using.
- In 'Dynamic,' 'Standard,' 'Entertain,' and 'Graphics' modes, the backlight flickers at 240Hz with the brightness at '19' and below, and is flicker-free at all brightness levels above that.
- In 'Movie' mode, the backlight flickers at 480Hz at all brightness levels.
- In 'Filmmaker' and 'Eco' modes, the backlight flickers at 240Hz at all brightness levels.
- In 'Game' mode, the TV is flicker-free across all brightness levels.
- With BFI enabled, the TV flickers at a very slow 60Hz.
The TV supports backlight strobing, more commonly known as black frame insertion (BFI). The feature is designed to improve the appearance of motion by strobing its backlight and reducing the amount of persistence blur. The BFI feature on the TV flickers at 60Hz, so there's still some image duplication present.
The TV has optional motion interpolation to help smooth out low frame rate content. It does an okay job with smoothing slower-moving scenes, but it struggles so much with faster scenes that there are noticeable artifacts, a screen-tearing type effect, and haloing around characters.
The Samsung DU8000 does a mediocre job of lessening the intensity of direct reflections, so mirror-like reflections are distracting, especially during darker scenes.
There's barely any noticeable increase in black levels when watching this TV in a bright room.
The total reflected light on this TV is okay. Direct reflections are distracting on this model since they're very visible during dark scenes, and there's some light banding. However, the TV's coating does an alright job handling glare from indirect reflections.
The TV has mediocre percieved color volume in a bright room. Low-luminance colors lose saturation as the amount of light in your room increases, but mid-luminance and high-luminance colors are mostly unaffected.
The TV's viewing angle is mediocre, so the TV isn't a good choice for wide seating arrangements. There's significant color shifting and brightness loss as you move off-center, and the image looks increasingly washed out as you move further away to the sides. If you're looking for a budget-friendly TV and need one with a wider viewing angle, take a look at the LG UT75.
The Samsung DU8000 has unremarkable gray uniformity. The sides of the screen are darker than the center, and there's some noticeable dirty screen effect towards the middle of the screen with large areas of uniform color. On a very dark or near-black screen, its uniformity is good, but the sides are noticeably brighter than the center.
The TV uses a BGR (Blue-Green-Red) subpixel layout instead of the traditional RGB layout. For video or gaming content, this doesn't cause any issues, but for PC monitor use, it can be a problem as it can impact text clarity.
The TV uses a KSF phosphor coating to produce red light, with high peaks on reds and blues. This model does have good separation between colors, giving it solid color purity and a wide color gamut.
The TV is limited to HDMI 2.0 bandwidth, but the 85-inch model does include HDMI 2.1 bandwidth on some of its ports.
The TV has eARC support, which allows it to pass uncompressed high-quality audio from a connected source to your home theater system or soundbar. Unfortunately, it doesn't support any DTS formats that are commonly used on many Blu-rays.
The Samsung UN65DU8000FXZA looks good for an entry-level model. It's a thin TV with slim bezels on three sides and a slightly thicker one on the bottom. Overall, it looks premium.
The TV uses two plastic feet that support the TV well. The footprint of the 65-inch stand is 42.2" x 3.2".
The height of the feet is adjustable, and you can set them to two different positions. The lower position, which you can see in the photo, puts the screen close to the table. The other position is high enough that most soundbars fit below the screen. The height of the lower position is 2.1", and the higher one is 3.07".
The back of the TV is identical to the Samsung CU8000. It's made entirely out of plastic and has etched horizontal lines. There are two ports that directly face the back and a cutout where you'll find the rest of the inputs, so these can be hard to reach if you have the TV wall-mounted. The TV has channels on the back and comes with a clip that can be attached to either foot for cable management.
The Samsung UN65DU8000FXZA has mediocre build quality. It's made entirely of plastic, and there's some wobble from front to back, but the TV recovers quickly. There's also some flex on the back of the TV that increases near the VESA mounting points, but this doesn't cause any issues. However, there's a large gap between the area where the screen meets the border. We don't know if this is isolated to our unit, but it's concerning.
The TV comes with the 2024 version of Samsung's proprietary Tizen OS but has a reduced feature set compared to more expensive models, so you don't get features like TV to Mobile or Ambient Mode+. Still, it's fast and easy to use and supports Samsung's popular Multi View feature.
Like most TVs, there are ads on the home screen. You can't disable them completely, although you can turn off targeted ads.
The Samsung DU8000 TV comes with the same minimalistic remote as the 2023 Samsung CU8000. The remote has a rechargeable battery that you can charge via USB-C or solar power. It has buttons for popular streaming services, and the voice control gives you access to Bixby and Alexa. You can ask it to change settings, switch inputs, and answer basic questions, but it can't search for content within apps.
There's a single button underneath the Samsung branding on the right side of the TV. You can turn the TV on/off, change channels, adjust the volume, and select inputs.
The TV's frequency response is mediocre. It sounds well-balanced at moderate levels, but sounds progressively worse as the volume increases. At maximum volume, which isn't very loud, the TV doesn't sound great, so it's better suited for a quiet environment. Like most TVs, it lacks bass.
