As already suggested, the predecessor model, the X800G, performs slightly worse than the X800H. This becomes clear in the input lag of about 34ms. The older X800G can’t get as bright and has a worse viewing angle, although both have an IPS panel. Also, the Android operating system is not quite as smooth and the input lag is higher. This makes the X800H a really better successor to the X800G, which is not the case with all TVs and their followers.
Between the LG SM8600 and the Sony X800H, small differences can be seen. In contrast to the XH80, the SM8600 has local dimming, even if it isn’t particularly advanced. It also has a wider color gamut, better motion handling and a lower input lag. Nevertheless, it doesn’t get as bright as the XH800H and has a significantly smaller viewing angle. But it offers Dolby Vision in the sound range.
The biggest difference in this comparison can be seen in the Sony X800H Bravia’s IPS panel and the Samsung Q60T’s VA panel: While the IPS panel offers a much wider viewing angle, the VA panel of the QLED model is noticeably higher in contrast and brighter, making the Samsung Q60T more suitable for dark environments.
