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
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.

Sadly, it has narrow viewing angles meaning the edges appear washed out if you sit too close, and our unit has some uniformity issues.

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.
Popular TV Comparisons
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.
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.
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.
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.
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.
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 use 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.
