Hisense U6SF Pro  TV Review

The Hisense U6 Pro has good peak brightness in HDR. It's bright enough to bring out highlight details well in most HDR content, but the smallest details are dimmed and don't stand out as well as they should. Bright scenes are also very bright and stand out well.

There's no significant difference in peak brightness on this TV when you switch to Game Mode. Most games are bright and vibrant, but very small details are dimmed a bit by the TV's local dimming and don't stand out as well as they should.

This TV has excellent peak brightness in SDR. It's bright enough to easily overcome glare during the day, even when most of the screen is bright at once, like when watching sports.

The Hisense U6 Pro has excellent contrast. The local dimming feature does a fantastic job boosting contrast in most simple scenes, resulting in extremely deep blacks that are amazing. The native contrast of the panel is decent, so blacks remain fairly deep even in more complicated scenes where the local dimming feature can't keep up.

The lighting zone precision on the Hisense U6SF Pro is decent. There's some minor haloing and glow around bright highlights and subtitles on a dark background, but it's not too distracting. It looks worse when viewed from the sides, though.

Zone transitions on this TV are just okay. The TV's processing can't quite keep up with small, fast-moving objects on a dark background. There's noticeable flicker as objects move between zones, and the zones don't turn on quickly enough, causing the leading edge to appear darker than it should be.

Switching to Game Mode has no impact on dark details or local dimming performance.

The black uniformity on this TV is excellent. Blacks are a bit raised when local dimming is disabled, but still fairly uniform, with no obvious pinching or flashlighting around the edges. Turning on local dimming reduces black levels and results in a more uniform image overall in dark scenes.

The Hisense U6 Pro has decent color volume. It has very good coverage of the DCI-P3 color space, but can't display the full range of reds and greens. It has no trouble maintaining color saturation in lighter scenes, either.

Unfortunately, it struggles a bit more with the wider BT.2020 color space. It has far more limited coverage of this space, and can't display saturated reds, greens, or blues. It also struggles to maintain color saturation in lighter scenes, so colors look a bit washed out.

This TV has good color volume in HDR. Saturated colors in low-light scenes are displayed well thanks to its high contrast ratio. Colors are bright and vibrant in light scenes, and unlike in SDR, they're not washed out.

The Hisense U6 Pro has great accuracy before calibration. The white balance is the most significant issue, but even there, the errors are minor enough that most people won't notice them. The color temperature is very good, and most saturated colors are displayed accurately. Gamma tracking is a touch high, closer to 2.4 instead of 2.2, so most scenes are slightly too dark.

This TV is easy to calibrate. The settings work well and allow for a full range of adjustments, and the TV has nearly perfect accuracy after calibration. Color accuracy didn't improve much, but it was already excellent before calibration, so this doesn't matter much.

The TV has great accuracy in HDR before calibration. The color temperature is a bit on the cool side, with slightly too much blue, especially in lighter shades. It has excellent color mapping, though most errors come from luminance mapping rather than hue or chromaticity. The white balance is also excellent, and just darker shades looking a bit off.

Unfortunately, this TV doesn't calibrate well in HDR. While calibration improved it a bit, it's not a noticeable improvement. The color temperature is still a bit cool, and shadow details are a bit off.

The Hisense U6SF Pro has good PQ EOTF tracking. Shadow details are crushed slightly, but most midtones are displayed well. It boosts highlights near the TV's peak brightness, and content mastered at 600 or 1,000 nits cuts off sharply. Content mastered at 4,000 nits has a more gradual cut-off, which helps preserve fine details, but limits how bright they get.

This TV does an excellent job smoothing out compression artifacts from low-quality content, including most streaming services. There's some loss of fine details in the process, though.

This TV does a great job upscaling low-resolution content like DVDs. The image is sharp, with no obvious over-sharping artifacts.

The gradient handling on this TV is just okay. There's some minor banding in all shades.

The Hisense U6SF Pro has fantastic low input lag with all supported formats as long as you're in Game Mode. It also offers a low latency interpolation mode that can be used while gaming, which adds very little additional latency. This is great for increasing the frame rate of older games and consoles that don't have native frame generation support and are locked at lower frame rates.

This TV supports all common TV resolutions, up to a maximum of 144Hz with a 4k resolution or 240Hz at 1080p. It displays chroma 4:4:4 properly in all supported modes, which helps with clear text when used with a PC.

The TV supports a variable refresh rate to reduce tearing, and it's effective across an extremely wide refresh rate range thanks to its high maximum refresh rate.

Unfortunately, this TV has a terrible CAD at its max 4k refresh rate of 144Hz. Almost all motion is incredibly blurry, as the TV is simply too slow to complete each transition. Transitions are very drawn out, and while they're quick to get fairly close to the target shade, it's very slow to complete the transition, and there's a long blur trail behind fast-moving objects.

The CAD at 120Hz is essentially the same as it is at 144Hz. Motion is still noticeably blurry.

Unfortunately, dropping down to a 60Hz refresh rate results in an even higher CAD, and motion looks terrible.

The TV is fully compatible with everything the PS5 and PS5 Pro offer, like 1440p @ 120Hz and 4k @ 120Hz, as well as HDMI Forum VRR. It also supports Auto Low Latency Mode, so you don't have to worry about manually switching to Game Mode to get the lowest input lag.

The TV is fully compatible with everything the Xbox Series X|S offers, including 1440p @ 120Hz, 4k @ 120Hz, HDMI Forum VRR, FreeSync Premium Pro, and Dolby Vision gaming. It also supports Auto Low Latency Mode, so you don't have to worry about manually switching to Game Mode to get the lowest input lag.

Thanks to its slow response time, there's relatively little stutter on this TV. You'll still see some in very slow, panning shots, but it's minor.

Adding low levels of motion interpolation does a great job reducing stutter on this TV. The feature is very consistent, with almost no variation in frame time even in very busy scenes, and it significantly reduces how long each frame is held on the screen.

This TV removes judder from most content. The frame timing is slightly off with some European 25p content, but it's a very minor issue that most people won't even notice.

There's no micro judder.

Unfortunately, this TV has a very slow response time when watching content, and fast motion is extremely blurry. Unfortunately, enabling the high refresh rate mode actually makes it worse.

There are a few minor color artifacts in fast transitions, but they're not very noticeable. The edges of transitions are noticeably softer than the center, though.

The Hisense U6 Pro uses pulse width modulation (PWM) to dim its backlight, which introduces flicker that can bother people who are sensitive to it. Fortunately, it flickers at an extremely high frequency in all picture modes, at all brightness levels, and with local dimming enabled, so it's not visible. There's a secondary wobble at 120Hz, though, but it's very minor and not the same as a full on/off flicker effect, so it's unlikely to bother anyone.

The TV supports backlight strobing, more commonly known as black frame insertion (BFI). In Game Mode it can flicker at either 60 or 120Hz, so it'll match the frame rate of the source to avoid creating a double image.

The matte anti-reflective coating does a great job reducing the intensity of direct, mirror-like reflections. They're still noticeable, but significantly fainter and not as distracting. It does spread the light out, though.

Ambient light has no noticeable impact on black levels.

The total amount of reflected light off the screen is good. There are no diffraction artifacts like rainbow smears, and indirect lights aren't too distracting.

Ambient light has no noticeable impact on the perceived color volume of this TV.

Unfortunately, this TV has a sub-par viewing angle. The image degrades rapidly as you move to the sides, with a very noticeable red tint, making it an unsuitable choice for a wide seating area.

The screen has mediocre uniformity. The center of the screen is very patchy, so anything with a uniform color in the center doesn't look good, especially sports. The sides of the screen are also significantly darker than the center, which is a bit more noticeable in all content. It looks a lot better in dark scenes, though.

This TV uses a VA panel with a BGR (Blue-Green-Red) subpixel layout. This doesn't cause any issues for video or gaming content, but for PC monitor use, it can be a problem as it impacts the text clarity, although not everyone will notice this. It uses a KSF phosphor coating to produce reds, and has a good overall separation of colors.

Unlike the higher-end Hisense U7SG, this TV uses an older HDMI chipset and only supports HDMI 2.1 bandwidth on two of its four inputs. It doesn't support the newer ATSC 3.0 standard, either, so you're limited to 1080p for over-the-air broadcasts.

The Hisense U6 Pro supports eARC, which lets you pass high-quality, uncompressed audio to a compatible receiver or soundbar through an HDMI cable. It supports all major audio formats, so you don't have to worry about compatibility with external sources.

The Hisense U6 Pro has an fairly nice design, with thin bezels on three sides. The bottom bezel is a bit thicker and juts out a bit with an angled design.

The pedestal feet offer good support, but can't be adjusted to a narrower position and take up a lot of space. They're also a little low, so larger soundbars won't fit in front of the TV without blocking some of the screen.

The back of the TV has a grid pattern identical to the Hisense U7SG. It gives the TV a bit of a premium look. The inputs face towards the left side when viewed from the front, and they're easy to access when the TV is wall-mounted. Unfortunately, there's absolutely nothing to help with cable management.

The Hisense U6 Pro has decent build quality. There are no serious flaws or quality control issues on our unit, but it's not very premium and mostly uses cheap materials.

This TV ships with the Fire TV smart interface. It has a modern interface that's easy to use and has a good selection of streaming apps.

Unfortunately, like most TVs, the interface contains ads. You can opt out of personalized ads, but this doesn't change the number of ads you'll see; they just won't be personalized to match your search and viewing history.

You can skip the network setup part during the initial setup and use the TV entirely offline, but most of the smart features won't work.

This TV was originally tested with FIRE OS 8.1.8.0.

Unfortunately, the TV's build-in speakers are sub-par. It has an okay sound profile at low and moderate listening levels, and dialogue is fairly clear and easy to understand. It just can't get very loud, though, and you may have a hard time hearing it in loud environments.
