The Hisense U8G replaces the 2020 Hisense H9G, and it's an impressive TV. Like its predecessor, it delivers impressive performance and good value for its price, competing against high-end models from other brands like the Sony X90J and the Samsung QN90A QLED. Overall, it performs very similarly to the H9G, but there are a few welcome improvements, like two HDMI 2.1 ports, as well as a significantly improved color gamut. This TV delivers impressive peak brightness, outstanding contrast, a great local dimming feature, excellent reflection handling, and a wide color gamut. It's a great gaming TV with low input lag, a fast response time, and great gaming features. Unfortunately, while some of the issues found on the H9G have been fixed, others are still present, and these could be deal-breakers for some people.

Note: There's some confusion around Hisense's naming scheme. The results listed here are only valid for the North American models. There are international variants, but they're completely different TVs. This review isn't valid for any of the U8G models released internationally.

Our Verdict

8.4 Mixed Usage

Overall, the Hisense U8G is an impressive TV. Thanks to its excellent contrast ratio, high peak brightness, and great local dimming feature, it's a great choice for watching SDR or HDR movies. Performance-wise, it has outstanding low input lag, excellent response time, and great gaming features like variable refresh rate (VRR), making it an excellent choice for gaming or use as a PC monitor. There are a few technical issues that might bother some people, but overall, it's a well-rounded TV that should please most people.

Pros
  • Outstanding contrast.
  • High peak brightness.
  • Excellent reflection handling.
  • Excellent response time.
Cons
  • Image degrades when viewed at an angle.
8.6 Movies

The Hisense U8G is an excellent choice for watching movies in a dark room; the impressive contrast ratio, great local dimming, and excellent black uniformity deliver an impressive viewing experience in a dark room. Blu-ray and UHD Blu-ray content displays without any noticeable issues, and even older DVD or cable content looks great. Due to the fast response time, you might notice some stutter when watching movies, especially in slow panning shots. There's a motion interpolation feature that can help reduce the amount of stutter, but this introduces the soap opera effect, so it's not a perfect solution.

Pros
  • Outstanding contrast.
  • Excellent black uniformity.
  • Low-resolution content is upscaled without any issues.
Cons
  • Noticeable stutter in low frame rate content.
8.2 TV Shows

The Hisense U8G is a great TV for watching TV shows during the day. It has great reflection handling and high peak brightness, so glare shouldn't be an issue for most people. Older, lower resolutions shows are upscaled well. The built-in Google Play Store has a huge selection of apps, so you're sure to find your favorite streaming service without having to resort to an external streaming box. It's not perfect though, as the image degrades when viewed at an angle, which might be an issue if you like to move around with the TV on.

Pros
  • High peak brightness.
  • Excellent reflection handling.
  • Low-resolution content is upscaled without any issues.
Cons
  • Image degrades when viewed at an angle.
8.0 Sports

The Hisense U8G is a great TV for watching sports, with some notable exceptions. It has excellent reflection handling and great peak brightness, so glare shouldn't be an issue for most people. It has a fast response time in brighter scenes, so the players look like players and not just a blurry shape on the screen. Lower resolution content, like cable sports, is upscaled well and looks almost as good as native 4k content. On the other hand, the image degrades when viewed at an angle, so if you like to watch the big game with a large group of friends, only those seated directly in front of the TV will enjoy it to the fullest.

Pros
  • High peak brightness.
  • Excellent reflection handling.
  • Excellent response time.
  • Low-resolution content is upscaled without any issues.
Cons
  • Image degrades when viewed at an angle.
  • Some noticeable dirty screen effect.
8.8 Video Games

The Hisense U8G is an amazing TV for playing video games, with a few exceptions. It has outstanding low input lag, a great response time, and full VRR support from any source. Games look great thanks to the excellent contrast ratio, and local dimming performs just as well in Game mode as it does in other picture modes. It's also extremely bright, and it has great reflection handling, so glare shouldn't be an issue. On the other hand, there are a few technical issues with this TV when gaming. Local dimming isn't available with VRR in some cases from an Xbox without making some sacrifices to picture settings, and VRR can cause ghosting issues with some games.

Pros
  • Outstanding contrast.
  • High peak brightness.
  • Outstanding low input lag.
  • Excellent response time.
Cons
  • Some technical issues in Game Mode.
8.5 HDR Movies

The Hisense U8G delivers an excellent HDR movie experience. It has an excellent contrast ratio, delivering deep blacks, and the local dimming feature is great. It can get extremely bright when displaying HDR content, and small specular highlights stand out. It also has an impressive color gamut, so you can fully enjoy the latest UHD movies. Unfortunately, with some HDR content, it doesn't follow the director's intent, causing most scenes to be displayed brighter than they should be.

Pros
  • Outstanding contrast.
  • High peak brightness.
  • Excellent black uniformity.
Cons
  • Most scenes are brighter than they should be.
  • Noticeable stutter in low frame rate content.
8.7 HDR Gaming

The Hisense U8G is an excellent TV for HDR gaming. It has impressive low input lag, a fast response time, and great gaming features, including Auto Low Latency Mode and support for a variable refresh rate. Image quality isn't hindered in Game mode, with the same great local dimming performance and high peak brightness as outside of Game mode. On the other hand, there are a few technical issues with this TV when gaming. Local dimming isn't available with VRR in some cases from an Xbox without making some sacrifices to picture settings, and VRR can cause ghosting issues with some games.

Pros
  • Outstanding contrast.
  • High peak brightness.
  • Outstanding low input lag.
  • Excellent response time.
Cons
  • Some technical issues in Game Mode.
8.3 PC Monitor

For the most part, the Hisense U8G is a great choice for a PC monitor. It has extremely low input lag, ensuring smooth mouse movements and a responsive experience in general, and it has a great response time. It also has great reflection handling, so glare shouldn't be an issue. Unfortunately, the image degrades when viewed at an angle, so you'll need to sit a comfortable distance from the screen; otherwise, the sides of the screen won't look the same. Also, like most TVs, it uses a BGR subpixel layout, which can be an issue for some programs.

Pros
  • Outstanding low input lag.
  • Excellent response time.
Cons
  • Image degrades when viewed at an angle.
  • BGR subpixel layout can cause text clarity issues in some cases.

  1. Updated Sep 08, 2021: We checked for proper 4k @ 120Hz support and retested audio passthrough. We also rechecked for red ghosting and checked if the EOTF is still over-brightened on the latest firmware.
  2. Updated Aug 16, 2021: We rechecked the red ghosting issue with varied content.
  3. Updated Aug 06, 2021: We tested the response time with a 4k @ 120Hz signal. We also changed 'HDMI Forum VRR' support to 'Unknown', as there's no way for us to know for sure, and we replaced our upscaling photos, as they were overexposed a bit.
  4. Updated Jun 21, 2021: Remeasured SDR peak brightness to confirm our results.
  5. Updated Jun 04, 2021: We incorrectly stated that this TV has a 2 point white balance calibration. We've corrected it to 20 point.

Market Context

The Hisense U8G is the second-highest 4k model in Hisense's 2021 lineup, just below the Hisense U9DG and above the Hisense U7G. Despite the similar name to the Hisense H8G, this model replaces the Hisense H9G, as Hisense appears to have shifted their lineup this year. Hisense aims to offer high-end performance at mid-range prices, and this model aims to compete with the high-end TCL models and much more expensive models from other brands, like the Sony X90J and the Samsung QN90A QLED.

Build Quality

It has good overall build quality. The stand supports the TV well, with little wobble. The border around the screen is metal, but most of the body is plastic. There's very little flex, except around the VESA mounts, but this shouldn't cause any issues.

Update 06/21/2021: We retested the brightness to confirm our results because we measured a lower brightness than the advertised 1500 cd/m². This is the brightest the TV gets. We measured a max brightness of 702 and 1,249 cd/m² in the 'Vivid' and 'Standard' Picture Modes, respectively.

The Hisense U8G has excellent peak brightness in SDR, very similar to the Hisense H9G, and glare shouldn't be an issue. Small highlights in some scenes stand out really well, much brighter than the Hisense U6G. There is some variation in peak brightness in very bright scenes. This results in a slightly dimmer screen with some content, like watching a hockey game for example.

We measured the brightness after calibration in the 'Theater Night' Picture Mode with the Backlight set to 'Max' and Local Dimming to 'High'. Setting Active Contrast to 'Medium' results in a slightly brighter picture of 1,401 cd/m² in the 25% window, but it isn't a very noticeable difference.

Backlight
Full-Array

The full array dimming feature on this TV does a great job. With local dimming on 'High', dark areas on screen are dimmed, and there's very little black crush, so small bright points of light, like a star field, are still visible. Some scenes still show some blooming, but the algorithms appear to spread the backlight out over a few more zones than it has to, to smooth out the blooming a bit. This is a noticeable improvement over the Hisense U6G and a bit better than the Hisense U7G. Subtitles are very bright, but if there's a black background behind them, there's a bit of noticeable blooming.

As fast-moving objects move across the screen, the algorithm can't quite keep up with them, which causes a trailing backlight and the leading edge of the object to appear a bit darker. As each zone turns on and off, this transition is noticeable with our test pattern, but not in real content.

The 55" model we bought has 132 dimming zones according to Hisense. The 65" has 360 dimming zones, so it's likely that the local dimming feature is a bit better.

The local dimming feature performs the same in Game mode as in the other picture modes, which is great. There are some limitations, as local dimming isn't available in certain situations when connected to an Xbox if VRR is enabled on either the TV or the Xbox. Switching out of Game Mode or switching to a lower resolution on the Xbox appears to fix the issue.

Update 09/08/2021: We retested the EOTF with the latest firmware. Unfortunately, the TV is still displaying HDR content brighter than it should be, but it's slightly better.

The Hisense U8G has impressive peak brightness in HDR. Small specular highlights are brighter than the Hisense H9G and significantly brighter than the Sony X90J, but overall real scene brightness is about the same across all three. We took these measurements in the 'HDR Theater' Picture Mode, which is also the brightest HDR mode on this TV.

Unfortunately, this TV doesn't follow the EOTF properly, displaying almost all scenes in HDR brighter than they should be. If you're looking for an accurate image, this might disappoint you, as some scenes may appear a bit washed out compared to other TVs. Unfortunately, there's no way to correct this, but we have seen reports that Dolby Vision content does force the TV to follow the EOTF.

Update 09/08/2021: We retested the EOTF with the latest firmware. Unfortunately, the TV is still displaying HDR content brighter than it should be, but it's slightly better.

Switching to Game Mode results in essentially no change in the HDR peak brightness. Like in the 'HDR Theater' Picture Mode, in Game Mode, the peak brightness doesn't track the EOTF properly, so almost all scenes are brighter than they should be. Most games offer an HDR adjustment option, so this shouldn't be an issue for most people.

The Hisense U8G has decent gray uniformity, but there are issues that could be distracting if you're planning on watching a lot of sports. The corners are noticeably darker than the center of the screen, and there are three dark vertical bands near the center of the screen. Dark scenes are a bit better, with significantly less dirty screen effect. This can vary quite a bit between units, though.

As expected of a VA-type TV, the image degrades when viewed at an angle. The most noticeable issue off-angle is the gamma shift, causing the image to appear washed out. Colors stay accurate to a wider angle than the gamma, but it's not as good as IPS-type TVs, like the LG NANO90 2021.

Out of the box, the Hisense U8G has excellent color and white balance accuracy. There are some noticeable inaccuracies in certain colors, especially with shades of blue, but the white balance is excellent, and gamma is nearly flat, close to our target of 2.2. This is a significant improvement over the Hisense H9G and the Hisense H8G that we tested last year, but this can vary between units.

Update 06/04/2021: We incorrectly listed that this TV has a 2 point white balance calibration. We've corrected it to 20 point.

As the Hisense U8G already had excellent accuracy out of the box, calibration was tough to do and didn't improve the overall accuracy much. Color accuracy improved a bit, but the issues with shades of blue are still there. The white balance is now nearly perfect, but as it was already excellent, this isn't a noticeable improvement.

Like most TVs on the market, the Hisense U8G uses a BGR (Blue-Green-Red) subpixel layout instead of the traditional Red-Green-Blue layout. For video content, this doesn't cause any issues, but if you're planning on using this TV as a PC monitor, it might be an issue for text clarity. You can read more about this here.

The Hisense U8G uses Quantum Dot technology, similar to the Samsung's QLED lineup, like the Samsung QN90A QLED, and LG's NanoCell TVs, like the LG NANO90 2021. This allows for a wider color gamut than traditional LCD technology. This results in an excellent color gamut, with nearly perfect coverage of the DCI P3 color space used by most current HDR content and good coverage of the wider Rec. 2020 color space. These results are a good improvement over the 2020 Hisense H9G and even better than the Samsung QN90A QLED.

Update 09/08/2021: We checked the red ghosting on our unit with the latest firmware, and found that nothing changed.

Update 08/16/2021: We took another look at the red ghosting issue with this TV, trying different content from different sources. It's clearly present with some content, like The Crown, and we also noticed it in Daredevil. It's not noticeable in all content but seems to be more noticeable in warmer scenes. We also checked a few games on a PS5. In Call of Duty, we didn't notice any ghosting, but in Astro's Playground, it was really bad, with terrible ghosting everywhere.

The issue appears to vary between units, as some people online have reported TVs with no ghosting at all, whereas other people have reported serious ghosting in all content. Compared to our H9G, it's not as bad, but this could just be unit variance.

Update: 08/06/2021: We measured the response time with a 4k @ 120Hz in Game Mode from an RTX 3080. We found that the response time is about the same as our 4k @ 60Hz measurements. We measured an average 80% response time of 3.4ms and an average 100% response time of 9.4ms.

For the most part, the Hisense U8G has an excellent response time, resulting in clear motion in fast-moving scenes. Unfortunately, there are some exceptions. Transitions out of dark scenes have significantly slower transitions, resulting in noticeable ghosting behind fast-moving objects. This is common for displays with VA panels, though, and is known as black smear.

Like the Hisense H9G, there have been reports of red ghosting in some situations, and our U8G also has this issue. You can see it here along Olivia Colman's hairline in this image taken from The Crown, Season 3 Episode 5.

We've also received multiple reports of motion artifacts in Game mode, sometimes severe, when VRR is enabled. Our response time measurements are taken out of Game Mode, so they don't show this issue. We don't know if Hisense has any plans to correct this issue; let us know in the discussions if you've noticed it.

The Hisense U8G has an optional Black Frame Insertion feature, which can help reduce the appearance of persistence blur. The BFI feature behaves a bit differently than the Hisense H9G and the Hisense H8G, though, as it can't flicker at 60Hz, which causes duplications in motion when displaying 60Hz content. Note that our scoring here is based only on the supported modes, not how well the BFI feature performs.

Due to the Hisense U8G's relatively fast response time, there can be some issues with stutter with 24p content, like movies, as each frame is held longer on screen. This is especially noticeable in slow panning shots. If this bothers you, motion interpolation can help reduce it, but this comes at the cost of adding some soap opera effect.

Update 08/06/2021: We changed the HDMI Forum VRR result to 'Unknown'. Because this TV also supports FreeSync, and there's no option to switch between FreeSync and HDMI Forum VRR, there's currently no way for us to know for sure which format it's using.

This TV supports a variable refresh rate, and in our testing, it worked properly from multiple sources, including from an NVIDIA graphics card. We've received reports of a few issues when VRR is enabled, though, including noticeable ghosting in some games, and local dimming isn't available in some cases when playing on an Xbox with VRR enabled.

The Hisense U8G has outstanding low input lag, great for gaming or PC use. The 60Hz input lag is a bit higher than the best TVs on the market at the moment and about double the input lag of most monitors at 60Hz, but still low enough for most people. When running at 120Hz, the input lag is on par with the best TVs on the market and very close to most 120Hz monitors. This is great for gaming or use as a PC monitor, as you can respond quickly to the action on-screen.

Update 09/08/2021: We double-checked to see if the Hisense U8G could display a 4k @ 120Hz signal properly. Unfortunately, like the Sony X85J, text is blurry with a 4k @ 120Hz signal, regardless of the settings used. 4k @ 60Hz is displayed properly.

The Hisense U8G can display 1440p resolutions, but these formats aren't exposed in the EDID, so it has to be forced. You can do this either through custom HDMI settings on an Xbox or through your graphics card's control panel software as a custom resolution. Unlike the Hisense H9G we tested last year, 120Hz is working properly on all supported resolutions, with no dropped frames.

The Hisense U8G has a decent frequency response, similar to the Hisense H9G. As usual for a TV, there's almost no low bass, so it can't produce any rumble or thump. It's a bit boomy in the high-bass, and mid to high treble sounds are a bit under-emphasized, but otherwise, it has a well-balanced sound profile and can get quite loud.

The Hisense U8G's smart interface has been updated to Android 10, from Android 9.0 on the 2019 models. The interface has changed a bit, and the overall experience is much smoother and faster. The interface is very similar to the new Google TV interface on 2021 Sony TVs, like the Sony X90J, but there are some slight differences.

Remote App Hisense RemoteNOW

The remote has been updated a bit since last year. There are more sponsored buttons, and like usual, you can't reprogram them to your favorite streaming service. The remote has a built-in mic for voice control, and it works well for launching apps or changing inputs, but you can't use it to adjust settings on the TV.

Smart Features
TV Controls

It has pretty standard controls, similar to most TVs on the market. If you're concerned about privacy, there's a physical switch to turn off the built-in microphone, which is rare, and a nice touch.

Differences Between Sizes And Variants

We tested the 55 inch Hisense U8G (55U8G), and we expect our results to be valid for the 65 inch (65U8G) model, too. In Canada, this model is known as the Hisense U88G; we expect it to perform the same. Unfortunately, Hisense releases different product lines in different regions, so we don't expect our results to be valid for international models, even if they have the same name. We don't know any equivalent model outside Canada and the U.S.

 Size US Model Canada Model Local Dimming Zones
55" 55U8G 55U88G 132
65" 65U8G 65U88G 360

If someone comes across a different type of panel or their Hisense U8G doesn't correspond to our review, let us know, and we'll update the review. Note that some tests like the gray uniformity may vary between individual units.

The unit we reviewed was manufactured in March 2021, and you can see the label here.

Compared To Other TVs

The Hisense U8G is an impressive TV, with a few minor issues that could be deal-breakers for some. It offers impressive value, outperforming some far more expensive models from competitors, like the Sony X90J.

Vizio P Series Quantum 2021
65" 75"

The Hisense U8G and the Vizio P Series Quantum 2021 are both great TVs, but the Hisense is more well-rounded. They each have a high contrast, but the Hisense has better local dimming to display more uniform blacks. The Hisense has a much quicker response time, so motion looks better, and its gaming features don't have as many bugs as the Vizio as you can easily play 4k games up to 120fps.
