Update 02/15/2021: We previously indicated that 1440p @ 60Hz is supported natively, it is not. It only works through a forced resolution. We've also retested 1440p @ 120Hz, and it still doesn't work. 1080p @ 120Hz works and is supported natively.
Update 11/26/2020: We updated the TV to firmware version PKG6.0414.0055NAA and checked to see if it fixed the issues with chroma 4:4:4 at 4k @ 120Hz. Text looks a bit better, but it's still blurry, as seen in this photo.
Update 10/27/2020: We updated the TV to the latest firmware (version 6.0384) and retested it with an HDMI 2.1 source.
Update 09/30/2020: We've retested the X900H's ability to display proper chroma 4:4:4 with the latest firmware, as we've received reports that it functions in all picture modes. Unfortunately, the results haven't changed. Chroma 4:4:4 is only possible in 'Graphics' or 'Game' mode.
The Sony X900H supports most common resolutions, except for 1440p @ 120Hz. It properly displays 4k @ 120Hz and doesn't skip frames. Chroma 4:4:4 is supported at all resolutions, and only requires that you be in 'Game' or 'Graphics' mode. However, text looks a bit blurry with chroma 4:4:4 at 4k @ 120Hz, as you can see in this photo. For full-bandwidth signals like 4k @ 60 + 10-bit HDR, set HDMI Signal Format to 'Enhanced Format' for the input in use.
