>>105614340>Supported via extensions. Or possibly even without IDK I don't use tranny gimmick hardwareThere's no extension for HDR. Xorg also never supported sync for every display. Even if you have 2 monitors with same refresh rates they have time difference between their refresh intervals meaning one of displays won't get frame in time and will miss it. Bring it up with VRR because it's too obvious.
As for VRR, Xorg doesn't support syncing to every monitor so it limits refresh rate to slowest monitor. There are hacky patch that allows VRR monitor to run in VRR monitor but it achieving that by running all the other monitors out of sync.

1. Xorg with compositing and Vsync has 1 frame delay guaranteed because no matter how good compositor at calculating compositing deadline it still has to send frame to display server itself, which will never present it before vblank deadline. That's fundamental flaw of compositing implementation in Xorg. https://zamundaaa.github.io/wayland/2021/12/14/about-gaming-on-wayland.html
