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!

    I’m not sure if this is the same issue, but one of my monitors had VRR supported on a NVIDIA card, but not on an Intel card. I ended up modifying the EDID to enable extd_timg and it’s been working fine since then. I wrote a blog post a while back here.
