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 65XS, 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

8.4 Mixed Usage

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.

Pros
  • Incredibly high contrast.
  • Amazing reflection handling.
  • Image remains accurate to a very wide angle.
Cons
  • Slow response time and terrible ghosting.
  • Colored bands in areas of uniform color.
9.2 Movies

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.

Pros
  • Incredibly high contrast.
  • Exceptional black uniformity.
  • Low-resolution content is upscaled without any issues.
  • Removes judder automatically from any source.
Cons
  • Colored bands in areas of uniform color.
8.3 TV Shows

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.

Pros
  • Amazing reflection handling.
  • Low-resolution content is upscaled without any issues.
  • Image remains accurate to a very wide angle.
Cons
  • Colored bands in areas of uniform color.
7.7 Sports

Unfortunately, the Hisense U9DG 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.

Pros
  • Amazing reflection handling.
  • Low-resolution content is upscaled without any issues.
  • Image remains accurate to a very wide angle.
Cons
  • Slow response time and terrible ghosting.
  • Colored bands in areas of uniform color.
8.3 Video Games

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. Like most TVs on the market, though, it can't display 4k @ 120Hz content properly.

Pros
  • Incredibly high contrast.
  • Amazing reflection handling.
  • Variable refresh rate support.
Cons
  • Slow response time and terrible ghosting.
  • Relatively high input lag.
  • Colored bands in areas of uniform color.
  • Can't display 4k @ 120Hz content properly.
8.8 HDR Movies

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.

Pros
  • Incredibly high contrast.
  • Exceptional black uniformity.
  • Outstanding local dimming feature.
  • Removes judder automatically from any source.
Cons
  • Colored bands in areas of uniform color.
8.0 HDR Gaming

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.

Pros
  • Incredibly high contrast.
  • Outstanding local dimming feature.
  • Variable refresh rate support.
Cons
  • Slow response time and terrible ghosting.
  • Relatively high input lag.
  • Colored bands in areas of uniform color.
  • Can't display 4k @ 120Hz content properly.
8.2 PC Monitor

The Hisense U9DG 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.

Pros
  • Image remains accurate to a very wide angle.
  • Variable refresh rate support.
Cons
  • Slow response time and terrible ghosting.
  • Relatively high input lag.
  • Colored bands in areas of uniform color.
  • Can't display 4k @ 120Hz content properly.

Market Context
Market Context
Market Context

The Hisense U9DG is a unique TV on the market. It's one of the first widely available TVs with dual LCD layers, designed to improve contrast and local dimming performance. It's the highest-end 4k model released by Hisense in 2021 and mainly competes with Mini LED TVs, like the Samsung QN90A QLED and the TCL 6 Series/R646 2021 QLED, as well as OLED TVs like the LG C1 OLED and the Sony A90J OLED.

Design
Design
Style
Curved No

The Hisense 75U9DG has a premium design, with very thin bezels on three sides and a nice metallic finish. The feet look very similar to previous high-end Hisense models, including the Hisense U8G, but they're set further apart.

Design
Stand

The stand is nearly the full width of the TV, but it supports it well, with just a bit of wobble. It lifts the TV high enough that almost any soundbar can be placed in front of it without blocking the screen.

Footprint of the 75" stand: 55.6" x 15.8" x 5.4" (to the first row of pixels).

Design
Back
Wall Mount VESA 600x400

The back is simple, but nice. It's a single large plastic panel, but it feels good. The inputs face to the sides and are easy to access, and there are tracks and clips on the legs for cable management, as well as a cover for the inputs.

Design
Borders
Borders 0.43" (1.1 cm)

The borders are very thin on three sides.

Thickness
Max Thickness 2.60" (6.6 cm)

The TV has fairly uniform thickness, and it's thin, so it won't stick out when wall-mounted.

Build Quality

The Hisense U9DG has great build quality overall. The metal feet are solid and support the TV well, but there's a bit of wobble, which is normal for a TV of this size. The back panel is plastic, and we noticed a bit of flex to it, but nothing serious. Our unit has an audible click when we turn the TV off, but this isn't an issue.

We found that the TV gets quite warm during use, so we took a few thermal images:

We don't take thermal measurements of TVs anymore, but this is warmer than most TVs we've tested in 2021. The front of the screen peaks at about 43°C, and the vents on the back of the TV are close to 48°C. While this doesn't cause any issues during use, it could reduce the lifespan of the TV, and it'll heat your room a bit.

Contrast

Thanks to its unique dual-layer technology, the Hisense U9DG delivers incredible contrast, resulting in extremely deep blacks if you're in a dark room. It has the highest native contrast ratio we've ever measured on an LED LCD TV, and it looks much better than any other IPS-type TV on the market. Enabling local dimming improves contrast even further, but the difference isn't very noticeable. It's not quite as inky as an OLED display, like the LG C1 OLED, but it's close. Note that contrast can vary between individual units.

The Hisense U9DG has good peak brightness in SDR, but there are some strange results. Smaller window sizes are much brighter than our real scene test clip. We double-checked this with real content and measured very similar results. 10% windows are also dimmer than 2% and 25% windows, which is also odd. We're not sure what's causing this strange variation in brightness with different scenes, but it's noticeable.

We measured the brightness after calibration in the 'Theater Night' Picture Mode with the Backlight set to 'Max' and Local Dimming to 'High'. Unusually, these settings also deliver the brightest picture overall.

The Hisense U9DG has an outstanding local dimming feature, the best we've seen on any LED LCD TV. It's thanks to its unique dual-layer panel. Unlike most TVs, the U9DG has a 1080p grayscale panel sandwiched under the main ADS (IPS-family) panel, which acts as a local dimming layer. The grayscale layer controls the amount of light that passes through it before hitting the color filters. It's as if the TV has slightly over 2 million local dimming zones.

This high zone count allows for extremely precise control of the light levels of each pixel. Bright highlights are incredibly bright, with almost no blooming at all. It achieves this without crushing blacks, and there's no loss of fine details in dark scenes. Star fields look incredible, with no noticeable loss of details. If you look closely at the TV, it's possible to see the zone transitions, but it's not noticeable with real content. The videos here were filmed with the Local Dimming on 'High'.

Even with Local Dimming disabled, this TV still looks better than most LED LCD TVs on the market. Visually, there's very little difference in black levels between 'Off' and 'High'. Setting it to 'High' boosts bright highlights significantly and results in a more impactful image.

The Hisense U9DG has just okay peak brightness in HDR. Like with the peak brightness in SDR, there are some strange results. Most highlights are very bright, but large bright scenes, including our real scene test, are significantly dimmer. Specular highlights stand out well in dark scenes, but bright scenes aren't bright enough for a true cinematic HDR experience. This change in brightness can be very noticeable with some content. Unfortunately, like the Hisense U8G, the EOTF doesn't track properly, as most scenes are a bit too bright.

We measured the HDR brightness in the 'HDR Theater' Picture Mode with Brightness at max, Color Temperature set to 'Low', and Local Dimming set to 'High'. If you want a brighter image, and accuracy isn't important to you, set Active Contrast to 'High'. This results in a brighter image, with a peak brightness of 1189 cd/m² with a 25% window, and a significantly brighter image in most scenes, as shown in EOTF.

The Hisense U9DG has good gray uniformity overall, but there are some issues. The sides of the screen are a bit darker than the center, but it's not that noticeable. There's just a bit of dirty screen effect. Near-dark scenes look even better, with almost no noticeable issues. Gray uniformity can vary between individual units.

Unfortunately, there are noticeable discolored bands across the screen that seem to shift as you move off-angle. They're especially noticeable with lighter scenes, so we took a photo with a white uniform slide.

Unfortunately, the Hisense U9DG has fairly high input lag, even in 'Game' mode. While it's not bad for casual console gamers, it's much higher than most TVs we've tested in 2021. Unfortunately, we couldn't measure the input lag at 120Hz, as the TV skips frames when sent a 120Hz signal with the variable refresh rate feature disabled. Input lag outside of 'Game' Mode is also higher than usual.

The Hisense U9DG supports most common formats, and it can display chroma 4:4:4 properly with most common formats. Unfortunately, text is blurry with 1440p @ 120Hz signals, and it has the same resolution-halving bug as most 2021 TVs we've test when sent a 4k @ 120Hz signal, so we don't recommend it for gaming at 4k @ 120Hz.

Sadly, there are a few bugs with this TV, and it skips frames in certain scenarios. When sending a 120Hz signal, it always skips frames unless the variable refresh rate signal is enabled. It also skips frames most of the time when sending a 60Hz signal to the HDMI 2.1 ports if you have the HDMI Format setting set to 'Enhanced Format'. It doesn't skip frames at 60Hz if you set that setting to 'Standard Format', or if you use the two HDMI 2.0 ports instead.

The Hisense U9DG technically supports all features of the new consoles, but it's not great for gaming on them. 4k @ 120Hz isn't displayed properly as it halves the vertical resolution, resulting in a 3840 x 1080 interlaced resolution. Gradients are also noticeably worse when gaming at 4k @ 120Hz, on both the PS5 and Xbox Series X. 120Hz gaming isn't working properly on the PS5 at the moment, as this TV skips frames when sent a 120Hz signal with the variable refresh rate disabled and the PS5 doesn't support VRR at the moment.

The Hisense U9DG has two HDMI 2.1 ports, and one of them is also the eARC port, which is disappointing if you have two of the new consoles or a recent PC graphics card, as you'll either need to get a receiver that supports HDMI 2.1 passthrough or limit some of your sources to HDMI 2.0. Unfortunately, the TV's EDID doesn't appear to include the correct HDMI 2.1 information, and our tools can't read the bandwidth of the ports.

The Hisense U9DG has an okay frequency response. Like most TVs, it has a high low-frequency extension, so there's almost no thump or rumble in its bass response. Above the LFE, the frequency response is well balanced, resulting in clear dialogue, but it dips in the higher treble ranges. It gets very loud, but there's a bit of compression at max volume.

Hisense has chosen not to upgrade their user interface to the new Google TV interface used on many Sony models. Instead, the Hisense U9DG runs a recent version of Android TV. The interface is easy to use, and it has a great selection of additional streaming apps. We didn't notice any bugs with the user interface, but the ghosting from the slow response time is apparent, even when browsing the menus.

The remote is identical to the one included with the Hisense U8G. It's simple but easy to use. It has a built-in microphone for voice controls, which you can use to change inputs, launch apps, search for content, or search the web. There's also a hands-free microphone on the TV that offers the same voice controls.

There's a five-way joystick on the back of the TV that you can use to control the basic functions of the TV. There's also a switch on the bottom bezel that allows you to disable the built-in microphone.

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.

Compared To Other TVs

The Hisense U9DG is an impressive TV, but some significant issues with it might be deal-breakers for some users. It's best-suited only for watching movies in a dark room, so unless that's your only use for it, there are much better TVs available for significantly less.

See our recommendations for the best 4k TVs, the best 70-75-77 inch TVs, and the best movie TVs.

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

The LG C1 OLED is better overall than the Hisense U9DG, but they use different panel technologies, each with their own strengths and weaknesses. The LG has much better motion handling, so it's a better choice for sports fans or gamers. The Hisense is a bit better for watching movies in a dark room, as it has less stutter and variations in brightness with different scenes. Large bright scenes are also considerably brighter on the Hisense. Finally, burn-in can be an issue on OLEDs like the LG, but the Hisense is immune to it.

Hisense U8G
55" 65"

The Hisense U8G and the Hisense U9DG each have their own strengths and weaknesses, so the best one depends on your usage. The U9DG has much better contrast and a better local dimming feature, so it's better for watching movies in a dark room. On the other hand, the U8G has better motion handling, so it's better for gaming or watching sports.

TCL 6 Series/R646 2021 QLED
55" 65" 75"

The TCL 6 Series/R646 2021 QLED and the Hisense U9DG each have their own strengths and weaknesses, so the best one for you depends on your usage. The TCL has much better motion handling and lower input lag, so it's better for gaming or watching sports. The Hisense has much better contrast and better local dimming, so it's a better choice for watching movies in a dark room.

Sony X95J
65" 75" 85"

The Sony X95J and the Hisense U9DG have different strengths and weaknesses, so the best one depends on your usage. The X95J has much better motion handling, so it's a better choice for gaming or watching sports. The Hisense has better contrast and a slightly better local dimming feature, so it's a bit better in some ways for watching movies. On the other hand, the Sony has better processing, and it's a lot brighter in HDR, so it's a better choice if you care about an accurate image when watching movies.
