The Sony XBR65X750D is a mid-range 4k TV with slightly above average picture quality. Even when viewed at an angle, the picture quality remains the same. It is very good at handling motion, with very little blur following fast moving objects. Unfortunately the low contrast ratio results in a less defined image in a dark room.
The design of the X750D is similar to the Sony TVs from 2015, such as the X850C. It looks good, with a thin bezel and metallic stand. The TV has an average thickness, and so will stick out from the wall a bit if mounted.
The Sony XBR65X750D has an average picture quality. The contrast ratio is bad and the black uniformity is average resulting in a poor performance for any dark room. Peak brightness and gray uniformity are also average and it offers no local dimming option. It has a good 10 bit panel, and the colors are good for SDR content. Upscaling performs well and the picture quality remains when viewed at an angle.
The contrast ratio of the Sony XBR65X750D is very low and is a bit disappointing, even for an IPS panel TV. This results in poor blacks that appear more like gray than really black.
The video has been taken for reference, but the X750D does not support local dimming. It has a direct backlight, unlike the edge-lit X800D.
Peak brightness is average, sitting at around 340cd/m² for all of our test window sizes. The brightness does stay the same over time and does not vary depending on the size of the test windows, which is good.

Update 10/21/2016: We have retested with the newest firmware update and a HDR10 signal, and found the peak brightness to increase across all window sizes.
The gray uniformity is average for the Sony XBR65X750D. We can clearly see that the 4 corners are more dark, but the rest of the picture is a bit more uniform. Due to this, the dirty screen effect should not be too much a problem for sport fans, where panning shots over a uniform surface are more common than normal TV content or movies.
The viewing angle of the Sony X750D is very good. The contrast is maintained at an angle far beyond most other TVs we have tested, making this TV a very good option to anyone who watches TV from wide seating positions.
The black uniformity is below average but it is not the worst, when compared with other IPS TVs. There is some clouding visible on our test picture but luckily, it is not too visible when watching normal content.
The X750D uses an 10 bit panel. It displays the gradient quite well, when sending a 10 bit signal the 10 bit gradations look smooth overhaul with some little imperfection in the dark green and the light red. But it is nothing really dramatic and should not cause problem when watching a normal movie.
Update 09/15/2016: Our original test was showing an incorrect color depth of 8 bit due to some incorrect drivers on our system, but after some correction to our test apparatus, we tested again the color depth and we can confirm that the Sony X750D does in fact have an 10 bit panel.
Prior to calibration, the white balance is quite good, but the colors are a bit off. For most people a calibration is not necessary to get good results.
The 11 point calibration works well to fix issues with the white balance. After calibration the colors still had some issues. You can find our calibration settings here.
The XBR65X750D doesn't support a wide color gamut. Colors are good enough to display SDR content well, but are missing the increased saturation to enhance HDR content.
The Sony X750D present some image retention, but unlike the X700D, the retention is less strong and look totally different. Here the image that get retain look more like a negative image of the burn-in scene. The image retention is also less strong and last a bit less longer than what we had on the X700D. After 6 minutes of recovery, the retention was not noticeable anymore.
Has a semi gloss finish, which diffuses reflections. For an average room, this should not be a problem. This will only be an issue if there are a few bright lights directly on the TV.
3D is not supported on the 750D.
The XBR65X750D handles motion well. It has a quick response time which results in very little motion blur. It is able to play movies smoothly from any source, and has motion interpolation options for those that like the soap opera effect.
The X750D has a quick response time, which works well to produce little motion blur. There is a small amount of overshoot but this is a great result, and the TV has no issues with fast motion.
By default the backlight does not flicker, but it is possible to achieve this by adjusting 'MotionFlow'. This helps to clear up motion.
The XBR65X750D is judder free when watching movies from 24p or 60i/60p sources without any problem. For a judder-free experience when watching movies with 60i or 60p sources like a cable/satellite box, you need to set the 'Motionflow' option to 'True Cinema' in the 'Advanced Settings' of the 'Picture Adjustments'. 24p signals do not require any setting adjustments to play smoothly.
The TV can interpolate content from 30fps or 60fps up to the native refresh rate of 120fps.
The Sony X750D has good input lag that should please any casual gamers out there. Those looking to use the XBR65X750D as a computer monitor will be pleased with the clear text due to chroma subsampling support. There are a wide range of inputs to connect old and new devices.
1080p input lag is good and should be enough for any casual gamer. To achieve the lowest input lag, set the picture mode to 'Game' or 'Graphics'.
Update 10/21/2016: We have retested with the newest firmware update and a HDR10 signal.
To display Chroma 4:4:4 set the scene to 'Graphics' or 'Game'. HDMI ports 2 and 3 accept a 4k @ 60Hz @ 4:4:4 signal, but only when 'Enhanced HDMI' is enabled in the input settings. The XBR65X750D does accept a 1080p @ 120Hz resolution, but can only display half of the frames, even though it is a 120Hz TV.
The X750D does not support HDR10 at the moment, but is planned to with a future firmware update.
Update 10/21/2016: With the newest firmware update, HDR10 is now supported.
As with most other large TVs, the sound of the X750D is poor. It suffers from significant distortion at all volumes and poor frequency response. Even a cheap sound bar would be a significant improvement.
Note: Sound Quality test for TVs reviewed before 2017 was performed at 75dB, 85dB, and Max SPL. Starting 2017, the target SPL levels have been changed to 70dB, 80dB, and Max dB SPL.
Poor performance. The frequency response and low-end cutoff are poor regardless of volume, and there is compression and pumping present under heavier loads. On the other hand, the maximum loudness is good for a TV.
Poor distortion performance. The amount of harmonic distortion at 75dB and 85dB are low. There was audible aliasing present even at 85dB. at 100dB there's a dramatic jump in the harmonic distortion, which is typical of most Sony TVs. However, these artifacts will be less audible in real-life situations.
The Sony XBR65X750D features the Android TV platform with its latest iteration (Marshmallow 6.0.1). When compared to other smart platforms, the latest Android TV offers some of the widest variety of content, apps and games available. Even if the TV is slow to boot, once it is up and running, it is one of the fastest and most stable platforms out there. You can easily switch between all your connected devices and also view your personal photos and videos simply by connecting a USB flash drive.
The Sony X750D has a similar remote as most other Sony TVs, such as the X800D, but lacks the voice control button. It is possible to purchase the voice control remote separately, and this works with the TV. The provided remote is easy to use and provides quick access to most features.
We tested the 65" (XBR65X750D). This is the only size available at the moment.
If someone comes across a different type of panel or if their Sony XBR65X750D doesn't correspond to our review, let us know and we will update the review.
The Sony X750D is only available in 65", a very competitive size for TVs. It is a mid-range TV, lacking some of the features found in higher end models.
Update 10/21/2016: HDR10 is now supported.
