Changing refresh rate above 60hz causes half of screen to not render

S1NK · 2023-01-26 19:32:25

I am using xmonad on my Nvidia 1650, whenever i attempt to change my refresh rate above 60hz half of my screen stops rendering, ive tried using nvida proprietary drivers as well as nouveau drivers but neither work, ive tried changing via xrandr as well as installing kde and changing via kde settings. Has anyone had this issue, or does anyone know a solution for this issue?

I once tried nouveau and I had the same exact behaviour as you (my GPU is GTX1660S). Are you absolutely sure you were NOT using nouveau drivers / modules?

Post your xorg log and the "xrandr -q" ouput, https://wiki.archlinux.org/title/Xorg#General

@d.Alt, do you maybe have one of those outputs where two panels are built into one bezel?

That worked thanks, im not really sure why because i tried the nouveau drivers earlier and im not sure why it didnt work then but thanks anyway.

I think d.Alt rather suggested that the nvidia drivers work for them and nouveau didn't?

I'm a pretty standard/average/boring/oldschool dude: for me, him is still good

Mmm... No, not that I'm aware of... Anyway, here's my output device: https://www.rtings.com/tv/reviews/samsung/q70-q70r-qled

I tried nouveau out of sheer curiosity (around April or May '22) onto my ArchLinux and Debian installations; then I also done some more testing with Live(s) USB(s): Fedora, Kubuntu, Manjaro and openSUSE.
I always got the same behaviour on all of my tests: changing to other resolutions (nouveau was defaulting to 3840*2160@30hz) always happened the video output to be "broken in half" (specifically: the upper horizontal part).

So your profile picture is drag…

specifically: the upper horizontal part

No, those monitors are always split horizontally (left/right)
Could be a VRR issue then (GSync ./. FreeSync) or nouveau uses a naive modeline instead of reduced blanking and the signal gets too much.
(You can compare "xrandr -v")

That's what I got:
