Weird refresh rate bug

Grub Wayland Gnome install.

I have a 180hz monitor, and a 60hz monitor. No issues at all when both are plugged in.

When I remove my second monitor. My 180 hz monitor flickers everytime I move my mouse. (By flicker i mean my screen goes blank for about a second and a half.) Reboot does not fix, VRR On/off doesn’t fix. Have to run at 120hz or lower for screen to not go blank

I have a work around. To anyone with the same issue and only a single screen setup.

My 180hz monitor has 2 HDMI ports. I plug them both into my GPU. Gnome should see 2 displays Set HDMI-1 to 180hz out and HDMI-2 to 60hz out.

Then I set the second “monitor” (HDMI-2 out) to mirror the first “monitor” (HDMI-1). Now I have a single monitor running at 180hz. And can free my second monitor to use with another desktop.

Would appreciate a fix that didn’t require me to have 2 displays listed in gnome.

Try the latest kernel from Nginx Directory

Downloaded kernel and header.
Updated both files. “sudo pacman update -U </path/to/tar.tz>”
Still can not run above 120hz without blank screen.
Back to plugging in 2 HDMI from my gpu into the same monitor

I will try a clean install using the latest image and then download, update and apply kernel and header 6.13.0-4 before customization of the system just in case something I’ve done has broken it. Easier to diagnose on default image. Ill update if issue persists shortly.

Fresh install. Only one screen plugged in during install. My 180hz worked just fine no issues at all. Plugged in second screen. Set main monitor back to 180hz and pulled HDMI on second screen. 180hz works fine? I am going to keep customizing my system to mirror what I did before and update here when my refresh rate breaks again to hopefully help someone who runs into this issue in the future or patch it out in the latest kernel.
