Hisense U6/U6H Review (50U6H, 55U6H, 65U6H, 75U6H) (2024)

Curved No

The Hisense U6H is a simple-looking TV that has a redesigned back and bottom bezel compared to its predecessor, the Hisense U6G.

Wall Mount VESA 400x200

The back consists of metal on the top portion and plastic where the inputs are. Most of the inputs are side-facing, and unlike the Hisense U6G, they aren't set into the TV, so they're easy to access unless you have the TV mounted flush against the wall. The feet also have clips for cable management.

Contrast

Native Contrast

The Hisense U6H has a great contrast ratio, but it's not quite as good as the Amazon Fire TV Omni QLED Series 2022. Its full-array local dimming feature helps it improve the contrast with Local Dimming on 'High'. Note that the 75-inch model has a different panel type with a worse contrast ratio.

—

The TV has okay blooming performance. There's some visible blooming around bright highlights or in dark areas when they're next to brighter ones.

Local Dimming

Backlight

Dimming Zones Count Of Tested TV

The TV has decent lighting zone transitions. The leading edge of bright moving objects is visibly dimmer, and there's visible haloing behind fast-moving objects.

—

Switching to Game Mode doesn't result in any noticeable difference in dark scene performance.

4000 Nit Tracking Delta

The Hisense U6H tracks the target PQ EOTF very well. Although all scenes are slightly brighter than intended, it's still great, especially with shadows and midtones. There's a slow roll-off towards the peak brightness, meaning it preserves bright details well. The EOTF looks nearly the same in 'FILMMAKER MODE', but that mode locks you out of most settings. If you find the image too dim, use the 'HDR Theater' Picture Mode with the Backlight Level at its max, and Local Dimming, Color Temperature, and Active Contrast each on 'High'. This makes midtones appear brighter, as you can see in this EOTF, but it doesn't change bright highlights.

The Hisense U6 has an impressive HDR color gamut as it displays a wide range of colors. It has incredible coverage of the commonly-used DCI-P3 color space, as well as decent coverage of the wider Rec. 2020 color space. Tone mapping is decent in each, but some brighter details are lost, and the TV struggles with accurately portraying saturated colors in the Rec. 2020 space.

The TV has fantastic pre-calibration accuracy in SDR. Most colors and the white balance are accurate, and the color temperature is also close to the 6500K target. Gamma is good, but some bright scenes are over-brightened.

The gray uniformity is decent. There's some vignetting towards the corners and a bit of dirty screen effect in the center that could get distracting during sports, but neither is a major problem. You can also see gray spots with large areas of bright, uniform colors (see the Build Quality section for more).

—

Std. Dev.

Native Std. Dev.

The Hisense U6 has good black uniformity, but it looks worse than the Hisense U6G because there's more blooming around bright highlights with local dimming enabled. Without local dimming, the screen looks closer to blue as there's some backlight bleed, but it isn't too bad, and the local dimming helps further deepen any blacks.

Color Washout

Black Level Raise

Gamma Shift

The TV has a narrow viewing angle that makes the image look washed out from the sides. It means it isn't ideal for wide seating areas, but note that the 75-inch model has a different panel type with a better viewing angle.

This TV has good reflection handling. It handles moderate amounts of light well and, combined with its good peak brightness, you won't have problems using it in most living rooms. However, don't place it opposite a window with direct sunlight because it struggles a bit more with handling that type of glare.

Smoothing

Detail Preservation

Unfortunately, this TV's processing with low-quality content is poor. It just doesn't smooth out macro-blocking and pixelization well.

—

Subpixel Layout

Type LED

Sub-Type

The Hisense U6H uses a BGR (Blue-Green-Red) subpixel layout instead of the traditional RGB layout. For video content, it doesn't cause any issues, but it impacts text clarity if you're planning on using this TV as a PC monitor, as some text looks blurry. You can read more about this here.

—

80% Response Time

100% Response Time

The TV has an okay response time, but there's noticeable smearing and motion blur with fast-moving objects. The backlight flicker also causes image duplication, as you can see with the trail R behind the logo. The motion handling looks the same in Game Mode as outside of it, as the motion blur is still there. If you like this TV but would prefer something with a faster response time, look up its successor, the Hisense U6/U6K.

—

Flicker-Free

PWM Dimming Frequency

The Hisense U6 uses pulse width modulation (PWM) to dim its backlight at all brightness levels in all picture modes. It's high enough that it shouldn't be too distracting, but it can also cause headaches if you're sensitive to flicker.

—

Min Flicker for 60 fps in Game Mode

The Hisense U6H has an optional backlight strobing feature, commonly known as black frame insertion, to reduce persistence blur. It isn't that effective as it causes image duplication and even some smearing.

—

Motion Interpolation (30 fps)

Motion Interpolation (60 fps)

The Hisense U6H has a motion interpolation feature to bring 30 fps content up to 60 fps. It doesn't seem to do much in the test pattern, but it interpolates some slow-moving content well. Unfortunately, there are artifacts with fast-moving content. You can enable motion interpolation in Game Mode, but it still looks the same as it can introduce artifacts.

—

Frame Hold Time @ 24 fps

Frame Hold Time @ 60 fps

Due to the slow response time, there isn't too much stutter with fast-moving content, as each frame isn't held on for too long.

The Hisense U6H automatically removes 24p judder from native apps and sources with a Match Frame Rate feature, which helps with the appearance of motion in movies. However, it doesn't remove 24p judder from 60Hz sources like a cable box.

The TV comes with a redesigned remote compared to the remote that came with 2021 Hisense TVs. Like most modern remotes, it lacks a Numpad, and there are quick-access buttons to popular streaming services. The mic built into the remote and on the TV gives you access to Google Assistant and Alexa, so you can ask it to search for content, open apps, and switch inputs.

—

There's a button underneath the center to turn the TV on/off and switch inputs. There's another button to turn off the mic built into the TV if you're concerned about privacy, and you can also use it for the Find My Remote feature.
