Btw, do you mean you downgraded DP to 1.2? I think there isn’t a DSC 1.4 (only DP 1.4 which has DSC 1.2, and DP1.4a with DSC 1.2a).
Do you have any more info/links about this? I’m curious, since I do have a Pro Display XDR, and I’ve been trying to understand for some time how exactly it’s able to reach its bandwidth, which is definitely a rabbit hole.
Apologies, you're right. DP 1.4 - just looked at the manual (for the LG 27GN750-B, though I know that many other monitors were affected). Has been a couple of years now.
Ironically, I too, moved to the XDR.
Downgrading to DP 1.2 improved the display options from DP 1.4.
