Resolution 8k

The Hisense U800GR 8k is Hisense's first 8k LED TV available in the United States. It comes with the Roku TV platform as its smart interface, which is user-friendly. It's only available in a 75 inch size, and its VA panel displays deep blacks, but like some other 8k TVs, its native contrast ratio isn't as good as 4k TVs with VA panels. It has a local dimming feature that helps further deepen any blacks, but it also causes blooming around bright objects. There are a few gaming features like its HDMI 2.1 bandwidth, variable refresh rate (VRR) support, and quick response time, but while it has low input lag with 4k games, it increases with 8k games. Also, it supports HDR10+ and Dolby Vision for HDR content, and it displays a wide color gamut, but its HDR peak brightness is just okay. Although the 8k resolution is meant to deliver crispier images compared to 4k TVs, there's also dithering with 4k and 8k signals, so it doesn't display these resolutions perfectly.

Our Verdict

8.0 Mixed Usage

The Hisense U800GR is very good for most uses. It's a great choice for watching movies in dark rooms because its VA panel has a high contrast, and the local dimming helps it display deep blacks, but there's blooming around bright objects. It's also good for watching movies in HDR because it displays a wide color gamut, but its HDR peak brightness is just okay. It's good for watching shows or sports in bright rooms, thanks to its high SDR peak brightness and excellent reflection handling, but it has narrow viewing angles, and it doesn't properly upscale 480p signals. Lastly, gamers should enjoy its HDMI 2.1 bandwidth, VRR support, and low input lag, but its input lag increases with 8k signals.

Pros
  • VA panel with high contrast ratio.
  • Local dimming helps it display deep blacks.
  • Excellent reflection handling.
  • Easy-to-use Roku TV.
Cons
  • Blooming around bright objects.
  • Dithering with 1080p, 4k, and 8k signals.
  • Narrow viewing angles.

The Hisense U800GR looks much like the Hisense U8G as it has the same textured plastic back, and the feet are similar. It has a stylish overall design, and it should look nice in most home theater setups.

Design
Stand

The metal stand has wide-set feet that place the screen high enough off the table so placing a soundbar in front won't block the screen. Sadly, there's noticeable wobble from front to back.

Footprint of the 75" TV: 56.1" W x 16.5" D x 3.3" H (4.1" to the bottom of the screen).

The Hisense U800GR is thin and doesn't stick out much when wall-mounted. The cable management clips stick out at the bottom, and they seem like they aren't meant to be removed, but the thickness of the TV without them is 2.95" (7.5 cm).

Build Quality

The Hisense U800GR's build quality is good. It's mainly made of plastic, and it feels well-put-together throughout, with no glaring issues. The metal feet feel solid, but there's still wobble from front to back. Sadly, the plastic on the back panel feels cheap and flexes easily, but this isn't an issue once you place the TV on its stand or mount it.

The Hisense U800GR has a great contrast ratio thanks to its VA panel. It displays deep blacks with the local dimming feature enabled, but its native contrast isn't as good as other 4k TVs with VA panels, like the Hisense U8G. However, it's still better than Samsung's 8k TVs like the Samsung QN800A 8k QLED. Keep in mind that contrast may vary between units.

The Hisense U800GR has good SDR peak brightness. It gets bright with small highlights, but it quickly loses its brightness with larger areas due to its Automatic Brightness Limiter, and its real scene peak brightness is only decent. Still, you shouldn't have many issues using it in a well-lit room.

We tested the brightness after calibration in the 'Movie' Picture Mode with the TV Brightness set to 'Brighter', Local Dimming on 'High', Color Temperature set to 'Warm', the Backlight at '100', and the Contrast at '90'. We couldn't get a brighter image with any other setting.

The Hisense U800GR's local dimming feature is decent. It has 180 zones, and overall, it's a decent implementation of local dimming, but it has some drawbacks. It doesn't crush blacks at all, meaning you won't lose details in scenes with small highlights like a star field, and objects transition between the zones well with real content. Sadly, there's noticeable blooming with any bright object on a dark background, especially with subtitles, and these are distracting even with real content. The blooming is the biggest downside of the local dimming, and while the TV looks decent from in front, the blooming becomes more noticeable as you move off-center.

Note: You can see in the real content video, particularly in the last scene with the people jumping, that there are two dead pixels in the center. We refreshed the TV, and they were still there, but they're not always visible, and this varies between units as not all units will have dead pixels.

The Hisense U800GR has alright HDR brightness. It gets brightest with small highlights, which is great as they pop, but the overall real scene brightness won't be enough to deliver a satisfying HDR experience. The EOTF is brighter than the target PQ curve, so most scenes are brighter than they should be until there's a sharp roll-off at its max brightness, causing a loss of details in bright highlights.

We tested it in the 'Dark HDR' Picture Mode with TV Brightness on 'Brighter', Local Dimming on 'High', Color Temperature set to 'Warm', and with Backlight and Contrast both at '100'. We got the brightest results with these settings, and if you find the screen is too dim, then set the Color Temperature to 'Normal'. This doesn't change the peak brightness, but it makes the image appear slightly brighter as you can see in this EOTF.

However, 1440p VRR doesn't tear in games on the Xbox Series X, meaning the TV supports it, but because our regular pendulum demo tears, we're leaving 1440p VRR as Unknown. Although the NVIDIA Control Panel with our RTX 3070 showed that it supports G-SYNC, there's constant tearing.

The Hisense U800GR has low input lag with most resolutions. Gaming feels responsive with 1080p, 1440p, and 4k signals thanks to its low input lag, but it increases a lot with 8k @ 60Hz signals, so it may not be ideal for some people playing reaction-based games. We remeasured the 8k @ 60Hz input lag a few times and kept getting the same results, consistent with the LG NANO99 8k 2021 and the LG QNED99 8k. Also, we couldn't get proper VRR input lag readings, which we experienced with the TCL 6 Series/R648 2021 8k QLED. We're looking into this issue, and we'll update the review once we fix it.

The Hisense U800GR displays most common resolutions up to 8k @ 60Hz. It also displays proper chroma 4:4:4 with any signal except for 1440p, as text looks fuzzy with 1440p @ 60Hz and 1440p @ 120Hz signals.

The Hisense U800GR has eARC support, which allows you to pass Dolby Atmos and DTS:X signals to a compatible receiver through an HDMI connection. Unlike the Hisense U9DG, its eARC port isn't one of the HDMI 2.1 ports, so you can connect a receiver and still use the other ports to connect gaming consoles.

The Hisense U800GR has an okay frequency response. It gets loud and has a fairly well-balanced sound profile, good enough for listening to dialogue, but it doesn't produce much bass.

The distortion handling is decent. Even at loud listening levels, there isn't too much distortion. However, this depends on the content, and not everyone may hear it.

The Hisense U800GR comes with the same remote as other Roku TVs, but it has a built-in battery instead of needing rechargeable ones. It has a mic for voice control, which you can ask to open apps, switch inputs, and search for content, but you can't change some settings. It has a Find My Remote function where it makes a noise in case you lose it, and you can use the remote hands-free feature by saying, "Hey Roku." You can use the '1' and '2' buttons to program voice commands, and you can press them to initiate the command instead of saying it every time. It also has an auxiliary input on the side, so you can plug in your earphones and listen directly through those if you don't want to disturb anyone.

Differences Between Sizes And Variants

The Hisense U800GR is Hisense's only 8k LED TV, and it's only available in a 75 inch size. This model is sold in the United States, and there's a similar model available in Australia, known as the Hisense U80G, but that has Android TV and not Roku TV. Because Hisense releases different models outside North America, our review isn't valid for any similar model.

If someone comes across a different type of panel or if their Hisense U800GR doesn't correspond to our review, let us know, and we'll update the review. Note that some tests, like gray uniformity, may vary between units.

Our unit was manufactured in June 2021; you can see the label here.

Compared To Other TVs

The Hisense 75U800GR is a great 8k TV that provides more gaming features than LG QNED99 8k or the LG NANO99 8k 2021, and its VA panel has a great contrast ratio. Its picture quality is very good, but considering it has dithering issues while displaying 4k and 8k content, and it doesn't properly upscale 480p content, it's worth getting a 4k TV like the Hisense U8G instead.

Also see our recommendations for the best LED TVs, the best Roku TVs, and the best 70-75-77 inch TVs.

Hisense U8G
55" 65"

The Hisense U8G and the Hisense U800GR 8k are LED TVs with different features. The U8G is a 4k TV available in 55 and 65 inch sizes and has Android TV, while the U800GR is an 8k TV available in a 75 inch size and uses Roku TV. Despite the higher resolution on the U800GR, the U8G performs better in a few areas like its higher peak brightness, better contrast, improved local dimming, and it displays 480p and 4k content better. They have similar gaming features, but the U800GR has a slightly quicker response time.

LG C1 OLED
48" 55" 65" 77" 83"

The LG C1 OLED and the Hisense U800GR 8k are two different types of TVs. The LG is a 4k TV with an OLED panel, resulting in a near-infinite contrast ratio, perfect black uniformity, and wide viewing angles. It also has a quicker response time and lower input lag than the Hisense. On the other hand, the Hisense is an 8k TV with an LED panel that gets brighter in SDR, and it doesn't suffer from the permanent burn-in risk that OLEDs have. Also, the Hisense is only available in a 75 inch size, while the LG is available in a wide range of sizes.

TCL 6 Series/R648 2021 8k QLED
65" 75"

The TCL 6 Series/R648 2021 8k QLED and the Hisense U800GR 8k are similar 8k TVs with Roku TV. The TCL uses Mini LED backlighting that lets it get much brighter, especially in HDR, and it also has a higher contrast ratio. They have similar gaming features, but the Hisense has a slightly quicker response time. The Hisense is only available in a 75 inch size, while the TCL is available in 65 and 75 inches, but other than that, the differences are minimal.

LG QNED99 8k
65" 75" 86"

The LG QNED99 8k and the Hisense U800GR 8k are both very good 8k TVs with different features. The LG has an IPS panel with wider viewing angles, and despite having a lower contrast than the VA panel on the Hisense, it has Mini LED backlighting that allows it to have decent local dimming. Also, the LG gets brighter, especially in HDR. Still, the Hisense is better for use in dark rooms because it has better black uniformity. The Hisense is better for gaming because it has a quicker response time, and it has VRR support, which the LG doesn't have.

LG NANO99 8k 2021
65" 75" 86"

The LG NANO99 8k 2021 and the Hisense U800GR 8k are different types of 8k TVs. The LG has an IPS panel with wide viewing angles, and it's available from 65 to 86 inches, while the Hisense is only available in a 75 inch size and has a VA panel with better contrast. The LG does a better job at upscaling lower-resolution content, and it doesn't have any dithering issues like the Hisense. The Hisense is better in dark rooms as it has a better local dimming feature, and it has more gaming features like VRR support.
