Lower brightness is the key difference
When comparing the Sony XH80 vs. the X80J, it is obvious, that new doesn’t always have to be better. Almost nothing has changed in the design, except for a cable holder on the feet of the new Bravia. However, the 2021 model has taken a step backwards in terms of brightness. As a result, both the SDRStandard Dynamic Range – image/video with a conventional gamma curve (opposite: HDR) – “normal” videos and HDRHigh Dynamic Range – image/video with more dynamic range (contrast range) picture quality are worse than they were last year. Even though the good viewing angle and fast response time are obvious advantages for both TVs, there is still a drawback for the X80J in terms of gaming. The missing ALLMAuto Low Latency Mode – Automatically detects connected consoles and keeps input lag as low as possible. is noticeable, and the lack of an HDMI 2.1 port is also rather negative.
Even if the sound is a bit better than last year, the weaker picture quality is still there. The Sony’s picture is not fundamentally bad, but the X800H is a better choice in this comparison.
