Tearing with Odyssey G9 at max resolution

Attempt #2 at making a post, as, I messed up a bit, so my apologies if you saw that first one.

I’ve looked around the wiki quite a bit, as well as these forums for hours, and I don’t believe I’ve seen anybody talk about this topic, and it’s so niche that I doubt it would’ve come up anytime soon – so I decided to take matters into my own hands by asking for advice, lol. My apologies if this has been discussed already though, with that been said.

I have three displays, currently. I have a 2560x1440 144hz, a 1920x1080 60hz drawing tablet, and the problem child Odyssey G9 – a 5120x1440 240hz display. Back when I was on Windows and Arch Linux, I had few issues with this display, so this seems to be a Qubes OS related issue, to my knowledge. The problem is the main monitor (the Odyssey G9) tears when at max resolution, until the prompt to save settings goes away –

I’ve attempted to use Xrandr, but that only causes it to be the same, but a reboot is required,
as well as attempted to increase the GPU minimum VRAM as described in the wiki. Both to no avail; I kind of gave up a few months ago and have just been running it down-scaled, but at this point, I’m just wanting my full resolution, as, that’s what I paid a good chunk of money for. This tearing at max resolution only happens on the primary display I’m attempting to change.

Also the reason for the black parts of the screen, is I’ve removed the wallpaper entirely – I just prefer it to be black, just an odd personal preference, lol. I do not have NVIDIA drivers, either.

Does anybody have any ideas on what I could try? Any recommendations/ideas are highly appreciated.

what’s your cpu? also what cable you use?

I’m running an AMD Ryzen 3900x, NVIDIA RTX 3060 Ti, and I’ve attempted many different cables – none of which worked, unfortunately. Also the monitor outputs as DisplayPort 1.4.

whats the output of this in dom0 terminal

cvt 5120 1440 240

# 5120x1440 239.90 Hz (CVT) hsync: 398.96 kHz; pclk: 2885.25 MHz Modeline "5120x1440_240.00" 2885.25 5120 5600 6176 7232 1440 1443 1453 1663 - hsync +vsync

I had to type it out, as, I don’t know how to copy from Dom0 terminal yet, so my apologies if the format is a bit odd.

Edit: Oh, right. I have to run it in 120 Hz, I’ve never been able to get full 240 on any operating system except windows, and even then it crashed the OS multiple times – which is a problem with the monitor

Edit 2: Sorry, very scatterbrained rn from a really intense breakup. I’ll try cvt 5120 1440 120 real quick, as, that’s probably what you’re after.
