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’ve looked around but just haven’t found many viable options for some I know that Alienware made one awhile back but no longer do it looks like the poster that replied to you on this comment though found a pretty sweet deal which is awesome. Just smaller than what I would be wanting.
I want one that’s like 55"- 65" 120hz and has a display port and I haven’t been able to find a single one they’re all TVs full of spyware and no displayport options. (I have my current tv blocked on the router level from the internet)
I’d even just settle for a smart tv as long as it just had a display port. I might just have to switch to a monitor soon to get the most of my system. I would no joke be willing to save up and pay around 3K for a 55" to 65" monitor with 120hz and a displayport with no internet access. But they just don’t seem to exist from what I’ve seen.
nvidia have been promoting ‘big format gaming displays’ since I want to say about 2019. Some of them reach the dimensions you specify, I just hope these are VESA adaptive sync/FreeSync capable and not all GSync Ultimate module displays (they can be made to work in VESA mode but not without issues in my experience).
I think I’ve seen one or two obscure TV models offering DisplayPort over USB type C, it may have been from Hisense
