The Sony X800D is a 4k LED TV with good picture quality. It performs well in dark rooms due to the good native contrast. It handles motion very well, with little motion blur. It also has the bonus of a sleek look, and enough inputs to suit everyone. Unfortunately when viewed at an angle, the picture quality deteriorates. Note that the 49" model has a different type of panel which performs closer to the X700D, but with a wide color gamut.
The rear of the TV is all plastic. It features a narrow VESA mount, and a zip tie for cable management. If wall mounted, some of the inputs are hard to access.
The TV is quite thin, which is good. If wall mounted it will not stick out too far. Note that the 49" variation has a power brick, which may affect the mounting.
Picture quality is good on the 43" Sony X800D. It offers a great contrast ratio and good black uniformity. The color reproduction is also very good thanks to the wide color gamut and the very good 10 bit panel. It can also handle low resolution content and fight glare pretty well. Despite this, the X800D is not perfect and like a lot of mid range LED TVs it has some issues like the average gray uniformity and the picture quality deteriorates when viewed at an angle. The low peak brightness and the lack of local dimming feature also reduce the final picture quality score. Note that the 49" model performs differently, and is closer to the X700D but with a wide color gamut.
Contrast ratio is good for the Sony X800D. The blacks are fairly deep and should procure a good picture quality in a dark room. Note that the 49" variation has an IPS panel, and so the contrast ratio is expected to be closer to 1000:1.
There is no local dimming on the X800D. The video is for reference only.
The SDR peak brightness is average for the X800D, and it is about 100cd/m² less than what you get when in HDR mode. For a dark room, this result is enough but may be a bit dim for a very bright room.
The peak brightness is average. At around 375cd/m², it is good for dark room viewing, but may not be the best for a room with a lot of light. One thing is good though, it is that is does not change depending of the size of the test window and also it stays the same over a long period of time.
Gray uniformity is average on the X800D. The corners and side of the screen are a bit darker, but the center remains fairly homogeneous. Dirty screen effect should not be too much of a problem even for those watching sports like hockey, where it is usually very noticeable.
Viewing angle is not as good as an IPS panel, but not bad for an VA. The X800D keeps a good brightness, even at an angle, but it does lose a bit of contrast. Note that the 49" variation has an IPS panel, and so the viewing angle is expected to be better.
Black uniformity is relatively good. There is a bit of clouding on the test picture, but it should not be too noticeable during normal viewing.
The Sony X800D has a good 10 bit panel but it is not perfect. You can see see on our test picture that there is some small banding in the dark blue, dark green and also in the grayscale.
Update 09/08/2016: 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 X800D does in fact have an 10 bit panel.
Prior to calibration the results are good. The colors are a little over saturated, but the white balance is very good.
The calibration is quite easy, and provides good results. All of the issues with the white balance can be fixed easily. The colors remain over saturated. You can see our calibration settings here.
The X800D does a good job with low resolution content like DVDs. Small details are conserved and the final image does not look too soft.
1080p content like Blu-rays movies look very good and sharp once upscaled to 4k resolution. No details are lost.
The X800D features a wide color gamut. It covers almost all of the P3 space, which is great. When watching HDR content, colors are rich.
Note here that there is no image retention on the 43" version of the Sony X800D. Since we did not test the 49" version, which is an IPS TV (the 43" is a VA TV), we cannot say whether the 49" is retention free or not. But since IPS TV are more prone to image retention, there could be a chance that there is some image retention to some degree.
The X800D has a semi-gloss finish which helps to diffuse reflections. They appear larger, but are easier to see through. Deals with reflections well enough to provide good performance in an average room.
The Sony X800D is great at handling motion. It has a low response time which results in very little motion blur. It is able to interpolate content up to the native refresh rate of 60Hz. Those who are sensitive to judder may notice it when playing movies over a set top box or home theatre PC, but blu-rays and streaming apps play smoothly.
Great motion performance. Response time is low which is good, and results in only a short trail following the logo.
The X800D doesn't have backlight flicker by default, but it is possible to achieve this by adjusting 'MotionFlow'. The flicker frequency of 100Hz is a bit strange.
The Sony X800D does not present judder on 24p content when played from DVDs, Blu-rays or other 24p sources. Unfortunately even when using the 'CineMotion' setting, judder is present on both 60p or 60i, meaning that people who are sensitive to judder will notice when watching movies from a cable/satellite box.
The Sony X800D has a 60Hz panel. It can interpolate 30fps content up to 60fps. To do so without backlight flicker, change the 'MotionFlow' setting to 'Standard' or 'Smooth'.
This TV supports a wide range of inputs, which is great for those with lots of devices. It also features a low input lag which is good for most gamers. It has a 60Hz panel, and so can only display signals up to 60Hz. It also supports a wide range of resolutions, for those looking to use it as a PC monitor.
The input lag of the Sony X800D is quite low, which is good. To get the lowest input lag, select the 'Game' or 'Graphics' picture modes. This results in a lag of 33.3ms with an 1080p resolution, which should not be an issue for most people. When sending an HDR signal at 1080p, the input lag remains the same as under 'Game' or 'Graphic' mode.
Update 03/20/2017: The input lag has been retested with the latest firmware PKG6.0612.0004NAA.
The X800D accepts a 120Hz signal, but has a 60Hz panel so it can only display half of the frames. It supports chroma 4:4:4 at up to 4k @ 60Hz. To display 4:4:4, set the scene to 'Graphics' or 'Game'. This results in an input lag of 33.3ms. It accepts a 4k @ 60Hz @ 4:4:4 signal only HDMI 2 and 3, and requires 'Enhanced HDMI' to be enabled in the input settings.
There is one component in on the rear, which is shared with the composite in. There is also a composite in on the side, but the adapter for it is not included. An example of the adapter can be found here
The sound of the Sony X800D is below average. The frequency response is average, but it gets quite loud. Significant distortion occurs, especially at high volumes.
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.
Average performance. The frequency response is decent at lower volumes, however, there is compression and pumping present under heavier loads. On the other hand, the maximum loudness and low-frequency extension are above average for a TV.
Poor distortion performance. The overall amount of harmonic distortion at 75dB and 85dB are very low. However, as we've seen with other Sony TVs, there's a dramatic jump in the harmonic distortion amount at maximum loudness. There was also audible aliasing present. However, these artifacts will be less audible in real-life situations.
The Sony X800D comes with a modified Android Smart OS. It can be a little slow to start up, but works well, feels refined and seems very stable.It has a wide variety of apps pre-installed with the option of downloading many more from the 'Google Play store'. The X800D is also 'Google Cast' ready, meaning that you can cast content from any compatible iOS and android device without any additional hardware. Photos and video can be viewed directly from an USB flash drive. Access to the 'PlayStation now' cloud gaming service also gives access to many more games not available from the 'Google Play Store' .The X800D comes with a basic remote, but includes voice recognition which works well.
There are loads of apps which come pre installed, and access to the 'Google Play Store' allows access to almost anything. A web browser is available, as are the typical popular apps, like YouTube, Netflix, Amazon Video, and HBO Go. The X800D also includes access to the 'PlayStation Now' cloud gaming service.
There are no ads on this TV. Many featured apps add clutter on the home screen, though.
Controls are located behind the left side of the TV. They provide basic functionality and are easy to use, even when wall mounted.
Remote features voice recognition. This is the same remote used by some other Sony TVs, like the X850D.
We tested the 43" (XBR43X800D). Note that the 49" variation (XBR49X800D) has an external power brick, instead of the internal one in the 43". The 49" also has an IPS panel, so expect a lower native contrast ratio and wider viewing angle compared to the 43" model we reviewed and closer performance to the X700D but with a wide color gamut.
If someone comes across a different type of panel or if their Sony XBR43X800D doesn't correspond to our review, let us know and we will update the review.
