The Hisense U9DG is Hisense's flagship 4k TV in 2021, and it's a very unique TV. It's the first widely available TV that uses a dual-layer LCD panel, with a 1080p grayscale panel sandwiched underneath a 4k ADS (IPS-family) panel. The grayscale panel acts as a sort of local dimming layer and allows the TV to achieve much higher contrast and better local dimming than any other LED LCD TV on the market, especially for a TV with an ADS (IPS-family) panel. First announced in 2019, it was released outside North America in 2020 as the Hisense 65SX, but in a 65 inch version. Hisense has refined the technology and brought it to North America, but this time in a 75 inch size. It's an impressive TV overall, and Hisense has clearly shown that the technology works, as it has incredible contrast, an outstanding local dimming feature, and exceptional black uniformity. Sadly, many of the issues reported on the 65 inch version are still there; it has a slow response time, with terrible ghosting behind fast-moving objects, and the dual-layer technology produces bands of color in uniform screens that can be distracting.
Our Verdict
The Hisense 75U9DG is an impressive TV overall. It's best-suited for watching movies in a dark room, as it has incredible contrast and outstanding local dimming. Sadly, there are some serious issues with motion, so it's not recommended for watching sports or playing games, as there's terrible ghosting behind fast-moving objects. It can display a wide color gamut for the latest HDR content, but large bright scenes in HDR aren't bright enough.
- Incredibly high contrast.
- Amazing reflection handling.
- Image remains accurate to a very wide angle.
- Slow response time and terrible ghosting.
- Colored bands in areas of uniform color.
The Hisense 75U9DG is superb for watching movies in a dark room. It has incredible contrast, so blacks look black and uniform in a dark room. The local dimming feature is outstanding, with almost no blooming around bright objects and no loss of fine details in dark scenes. It removes judder automatically from any source, and thanks to the slow response time, there's almost no noticeable stutter.
- Incredibly high contrast.
- Exceptional black uniformity.
- Low-resolution content is upscaled without any issues.
- Removes judder automatically from any source.
- Colored bands in areas of uniform color.
The Hisense U9DG is a great TV for watching shows during the day. It has wide viewing angles, so the image remains accurate if you move around, and glare isn't an issue, as it has amazing reflection handling and good peak brightness in SDR. It upscales older 480 and 720p content well, and it has a huge selection of streaming services. Unfortunately, some colored bands throughout the screen can be distracting with certain content.
- Amazing reflection handling.
- Low-resolution content is upscaled without any issues.
- Image remains accurate to a very wide angle.
- Colored bands in areas of uniform color.
Unfortunately, the Hisense 75U9DG has a few issues that are likely deal-breakers for most sports fans. It has impressive viewing angles, good peak brightness, and amazing reflection handling, so it's great for a wide seating arrangement, and glare isn't an issue. Sadly, it has a very slow response time, and there's significant ghosting behind fast-moving objects, so sports don't look very good, and there are distracting colored bands across the screen.
- Amazing reflection handling.
- Low-resolution content is upscaled without any issues.
- Image remains accurate to a very wide angle.
- Slow response time and terrible ghosting.
- Colored bands in areas of uniform color.
Unfortunately, there are some serious issues with gaming on the Hisense U9DG. It has unusually high input lag, so it's not very responsive when gaming, and it has a slow response time, resulting in significant ghosting behind fast-moving objects. For slow, turn-based games, it might be okay for some gamers, but with any action scenes, it's almost unplayable. On the other hand, it supports FreeSync variable refresh rate technology, and it has two HDMI 2.1 ports for the new consoles.
- Incredibly high contrast.
- Amazing reflection handling.
- Variable refresh rate support.
- Slow response time and terrible ghosting.
- Relatively high input lag.
- Colored bands in areas of uniform color.
- Skips frames when sent a 4k @ 120Hz signal, unless you're using FreeSync.
The Hisense U9DG is an excellent TV for watching movies in HDR in a completely dark room. It has incredible contrast and an outstanding local dimming feature, resulting in deep uniform blacks with no loss of fine details in dark scenes and very little blooming around bright objects. It has an excellent color gamut, and it can display a wide color gamut. It has just reasonable peak brightness in HDR, though, but small highlights still really stand out in some scenes.
- Incredibly high contrast.
- Exceptional black uniformity.
- Outstanding local dimming feature.
- Removes judder automatically from any source.
- Colored bands in areas of uniform color.
Unfortunately, due to the issues with motion handling on the Hisense U9DG, we don't recommend it for gaming in HDR. It has unusually high input lag, so it doesn't feel very responsive when gaming, and it has a slow response time, resulting in significant ghosting behind fast-moving objects. On the other hand, it supports FreeSync variable refresh rate technology, and HDR looks good thanks to the high contrast ratio and wide color gamut.
- Incredibly high contrast.
- Outstanding local dimming feature.
- Variable refresh rate support.
- Slow response time and terrible ghosting.
- Relatively high input lag.
- Colored bands in areas of uniform color.
- Skips frames when sent a 4k @ 120Hz signal, unless you're using FreeSync.
The Hisense 75U9DG is a great TV for use as a PC monitor, but there are some issues with it. It has impressive wide viewing angles, so the sides of the screen remain uniform, even if you're sitting close to the TV. It can also display chroma 4:4:4 properly, so text looks sharp. Sadly, it has unusually high input lag, so it doesn't feel very responsive, and it has a slow response time, so there's significant ghosting behind fast-moving content.
- Image remains accurate to a very wide angle.
- Variable refresh rate support.
- Slow response time and terrible ghosting.
- Relatively high input lag.
- Colored bands in areas of uniform color.

Differences Between Sizes And Variants
We tested the 75 inch Hisense U9DG (75U9DG), which is the only size available. It was released in 2020 internationally in a 65 inch size, known as the Hisense 65SX, but that TV is a bit different, and our review isn't valid for that size. Unfortunately, the 75 inch model released in North America in 2021 doesn't appear to be available outside Canada and the U.S.
If someone comes across a different type of panel or their Hisense U9DG 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 August 2021, and you can see the label here.

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.
