I just noticed this update to a very old thread about broken DSC in macOS. I pretty much gave up on this ever being fixed and I am now shocked. :)

Can anyone confirm that 4K 144Hz HDR is actually available on an Ryzentosh using DisplayPort 1.4 DSC, in Sonoma?

If it works, I would be very tempted to upgrade from Ventura, even if WiFi/Bt stop working.

Add a new APFS volume and do a fresh install of Sonoma to test.

Huh, never actually tried making a separate volume. Will read-up and do a test over the weekend, thanks.

It freaking works!
The whole thing, 144Hz and even variable refresh rate option is there (although I haven't really tested it)

3 years later, they finally fixed it. This is glorious. I'll have to see about fixing the Wi-Fi with 94360NG card but man...wow.
