Sony X750H  TV Review

The Sony X750H has an excellent design. It looks clean and simple from the front, but the bezels aren't as thin as the higher-end models such as the Sony X950H, and they protrude a bit more from the screen. The stand is also simple and doesn't stand out in any way.

The feet are set at a narrower position than the Sony X750F by a few inches, which is great for those with a smaller table. The stand supports the TV well and there's almost no wobble.

Footprint of the 55" TV stand: 35.6" x 13.3"

The back of the TV looks a lot like the Sony X750F. The top portion is metal while the bottom portion is made of plastic. For cable management, there are two clips included in the box to tie the cables to the feet.

The Sony X750H has the same bezels as the Sony X800H. They're thicker than the higher-end 2020 Sony TVs and they protrude from the screen a bit.

The TV is of medium thickness and just slightly thinner than the Sony X750F. It doesn't stick out much when wall-mounted unless you use the back-facing inputs. Our unit appears to lean back a bit; however, your experience may vary.

The build quality is good. There's a lot of flex in the bottom plastic portion on the back, but since it's a part of the TV that doesn't get handled a lot, it shouldn't be an issue. The whole TV feels well-built and there's almost no wobble at all.

Unlike the Sony X750F, the Sony X750H has a VA panel with an outstanding contrast ratio, resulting in blacks that look deep in the dark. Note that the contrast ratio can vary between individual units.

The Sony X750H's SDR peak brightness is okay. Visibility should be fine in most rooms except in very bright rooms. There's a bit of frame dimming in the 2% window, but it's very subtle and shouldn't be noticeable in real content.

We measured the SDR peak brightness after calibration using the 'Custom' Picture mode, with the Gamma at '0', Brightness at maximum, and the Color Temperature set to 'Expert 1'.

If you don't mind losing image accuracy, you can make the image brighter by using the 'Custom' Picture Mode, with the Brightness at 'Max', Color at '50', and the Color Temperature set to 'Cool'. We can achieve a peak brightness of 398 cd/m² in the 10% window with these settings.

If you want a similar TV that can get brighter, take a look at the Vizio M8 Series Quantum 2020.

Update 07/26/2021: Added the real content local dimming videos.

The Sony X750H doesn't have a local dimming feature. The videos are for reference only, so you can see how backlight on this display performs and compare it to a similar product with local dimming.

Update 07/26/2021: Added the real content local dimming videos.

Since there's no local dimming, the backlight looks the same in Game Mode. The videos are for reference only, so you can see how backlight on this display performs and compare it to a similar product with local dimming.

Sub-par HDR peak brightness. Unlike the brightness in SDR, there's no dimming in the 2% window and is remarkably consistent across different content. It isn't really bright enough to make highlights stand out, though, so HDR content doesn't look much different from SDR content.

We measured the HDR peak brightness before calibration using the 'HDR Cinema' Picture Mode, with the Color Temperature set to 'Expert 2", Brightness at max, and Color at '50'.

If you don't mind losing image accuracy, you can make the image brighter by using the 'HDR Custom' Picture Mode, with the Color Temperature set to 'Cool', and all other image processing disabled. We can achieve a peak brightness of 407 cd/m² in the 10% window with these settings.

08/18/2020: We previously uploaded a low-resolution photo by mistake. It has been fixed. We have also re-evaluated the gray uniformity and increased the score from 5.8 to 6.3.

Mediocre gray uniformity. There's visible vignetting at the corners and a fair amount of dirty screen effect throughout the screen. Uniformity is a little better in dark scenes, but the unevenness is still visible and is worse in person. Note that gray uniformity can vary between units.

08/17/2020: We previously uploaded a low-resolution photo by mistake. It has been fixed. We have also re-evaluated the black uniformity and determined that the scoring was too high. The score has been changed from 9.5 to 9.1.

Black uniformity is outstanding; however, it's a little worse in person than what is captured in the photo. The backlight bleed on the sides and uniformity issues aren't as bad as the 5% window in the gray uniformity test, but they're still visible. Note that black uniformity can vary between units.

The Sony KD55X750H has sub-par viewing angles. Black level rises almost as soon as you move off-center, followed by gamma and color shift, so it isn't ideal for wide seating arrangements. If you need wider viewing angles, check out the Sony X800H, as it has an IPS panel.

08/18/2020: We previously uploaded a low-resolution photo by mistake. It has been fixed.

Decent reflection handling. The semi-gloss finish handles indirect reflections pretty well, but not direct reflections, so it's best to avoid placing it opposite bright light sources.

If you need a TV with better reflection handling, check out the LG UN7300.

The Sony X750H's out-of-the-box color accuracy is okay. Most of the color inaccuracies are difficult to spot. However, white balance is quite off, and the color temperature is on the warm side, giving the image a slight reddish tint. Gamma is perfect in darker scenes, but brighter scenes are over-brightened. Note that color accuracy can vary between units.

The color accuracy is exceptional after calibration. Gamma and white balance are nearly perfect, and the color temperature is much closer to our 6500K target. The remaining inaccuracies shouldn't be noticeable to the naked eye. You can see our recommended settings here.

480p content is upscaled well and without any issues.

08/18/2020: We previously uploaded a low-resolution photo by mistake. It has been fixed.

720p content looks good and there aren't any upscaling artifacts.

08/18/2020: We previously uploaded a low-resolution photo by mistake. It has been fixed.

The TV upscales 1080p content, such as from Blu-rays, well.

08/18/2020: We previously uploaded a low-resolution photo by mistake. It has been fixed.

Native 4k content is displayed perfectly.

The Sony X750H can't display an 8k signal.

The Sony KD55X750H has a BGR subpixel layout. It doesn't affect picture quality, but it can affect the way text is rendered when using the TV as a PC monitor, which you can read about here.

Good HDR color gamut. The DCI P3 numbers are much higher than what the chart indicates because we use the Rec 2020 exterior points to measure the color gamut. The EOTF follows the PQ curve almost perfectly until the roll-off, and it's the same when in 'Game' mode, which you can see here.

If you find HDR content too dim, you can make it brighter by using the 'HDR Custom' Picture Mode, with the Color Temperature set to 'Cool', Brightness set to maximum, and Color set to '50'. These settings result in this EOTF.

The color volume is okay. It displays dark colors well due to its high contrast ratio, but it can't display very bright colors.

08/18/2020: We previously uploaded a low-resolution photo by mistake. It has been fixed.

The Sony X750H's gradient handling is decent. There's visible banding in all colors, particularly in the grays. Unfortunately, there's no way to improve it.

08/18/2020: We previously uploaded a low-resolution photo by mistake. It has been fixed.

There are no signs of temporary image retention, even immediately after displaying our high-contrast static test image for 10 minutes, which is great. Note that temporary image retention can vary between units.

We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.

08/18/2020: We previously uploaded a low-resolution photo by mistake. It has been fixed.

Decent response time. There's only a short blur trail behind fast-moving objects, but there's significant overshoot in the 0-20% transition, resulting in some motion artifacts in dark scenes.

The backlight is flicker-free. The small amount of flickering at low brightness level is just noise.

08/18/2020: We previously uploaded a low-resolution photo by mistake. It has been fixed.

There's an optional Black Frame Insertion feature to help reduce motion blur. Unfortunately, it can only flicker at 120Hz, causing visible image duplication. To enable BFI, set MotionFlow to Custom and Clearness to max.

The Sony X750H is advertised as capable of interpolating lower frame rate content up to 60fps. However, it doesn't seem to be working at this time. We tried every combination of settings in different picture modes, but we couldn't spot any difference with it enabled, whether it was with our test pattern or in real content. It's likely a bug that can be fixed through a firmware update. We'll retest it once it's available.

Due to the TV's slower response time, there's only stutter in 24fps content.

The Sony X750H can only remove judder from native 24p content, but not if it's from a 60p or 60i signal, or from native apps. Setting MotionFlow to 'Custom' and Clearness to maximum can help, but it doesn't remove the judder completely.

The Sony X750H doesn't support any variable refresh rate technology.

The Sony X750H has outstanding low input lag. You only need to be in 'Game' mode to get the lowest input lag, and it's the same when using the TV as a PC monitor since changing the input label doesn't seem to have any effect.

Update 02/18/2021: We previously stated that the TV accepts 1440p @ 60Hz as a native resolution, but it's a forced resolution instead. The review has been updated.

The Sony X750H supports most common resolutions at 60Hz. 1080p @ 120Hz appears as an available option, but it skips frames. At the moment, we aren't able to display a proper chroma 4:4:4 signal, and changing the input label to 'PC' doesn't seem to do anything. This may be a bug that could be fixed in a future firmware update. To get the highest possible bandwidth for the HDMI ports, set HDMI Signal Format to 'Enhanced format'.

All the HDMI ports are advertised as being HDCP 2.3 compliant; however, this isn't something that we test for.

The TV supports ARC (Audio Return Channel) on its HDMI 3 port. There's no setting for it, it's enabled automatically when a compatible device is connected.

The Sony X750H has a decent frequency response. The sound is bass-heavy but there's barely any low-bass, so it can't produce a thumping or rumbling sound. It gets very loud, though, and there isn't too much compression when playing near max volume.

The distortion performance is bad. It isn't as noticeable at moderate volume levels, but it gets significantly worse when playing near max volume. That said, it also depends on the content.

08/18/2020: We previously uploaded a low-resolution photo by mistake. It has been fixed.

The Sony KD55X750H ships with Android 9.0, but it has a simpler user interface that looks more like the one on the Sony X700D. It feels a little laggy, which is why it takes longer to launch apps compared to other 2020 Sony TVs. Also, the motion interpolation feature doesn't seem to do anything. It's likely a bug that can be fixed via a firmware update; we'll retest it once it's available.

There's suggested content on the home screen and within the app store. We didn't see any ads during our testing; however, that can change with a future firmware update. You can opt-out of suggested content by disabling them in the settings menu.

The Google Play Store has tons of apps available to download. It lags a bit when launching an app, but it runs smoothly once you're in the app.

The remote has changed a bit from the Sony X750F and is the same one that comes with other Sony 2020 TVs. There's a built-in microphone and a dedicated button to summon the Google Assistant for voice control. Content search works for the most part and it can answer general inquiries, but some settings can't be changed via voice control, such as the TV's brightness.

The controls are located on the right backside of the TV. There are three buttons, and they allow you to turn the TV On/Off, change the channel, change the input source, and adjust the volume.
