I am a new owner of the amazing Asus ROG PG32UQX. Like the title says, is it capable of 10bit HDR at 4K 144hz or is 120Hz the limit for true 10bit HDR color? I’ve seen some reviews stating at 144Hz it drops to 8bit + FRC. Also, this is all under DSC(Display Stream Compression) and a DisplayPort 1.4 connection. Thank you for your time!

Also wanted to

mention I found out the maximum settings for HDR are 120Hz 10bit color at 4k using DSC without getting into any color sub sampling. For SDR it’s 4k 144Hz at 8bit color.

That does not sound right.  4K 144hz at 10bit requires DSC on DP 1.4, but it can run full RGB.

No problem.  There are quite a few pages of info, but there is some good stuff about settings mixed in throughout.
