I have an AMD Ryzen 7 9800X3D 4.7GHz processor and AMD Radeon RX 9070 XT setup hooked up to a Samsung S90D as a monitor. Running Fedora KDE Plasma.

I can enable 120hz and HDR from my settings but see no way to set VRR anywhere. It works with the Playstation so I know the tv is capable. I asked AI a couple times just to get a rough idea of things I could try and tried the command

kwriteconfig5 --file kwinrc --group Compositing --key "VRR" "true"

but didn't recieve a response so idk if this worked or not. Is this going to require installing AMD proprietary drivers? I briefly read a little about that and it looks like the process is quite a bit above my current skill level.

I saw a dev post about disabling Multi Stream Transport on the monitor but I could not find this setting on my tv anywhere so I think this may be a monitor only setting.

Any help or guidance would be greatly appreciated thank you so much in advance!
