How do I set custom Vsync and Hsync values in Wayland

Hello everyone,

I recently made the switch to Wayland and it is working fine. Unfortunately I can't get my Monitor overclocked like I did on X11.
On xorg I'd just use "xrandr --newmode "1920x1080_80.00"  198  1920 2008 2052 2200  1080 1084 1089 1125  +HSync +Vsync && xrandr --addmode DP-2 1920x1080_80.00 && xrandr --output DP-2 --mode 1920x1080_80.00 " and it was working fine.

Unfortunately I can't figure out how to do the same on Wayland. I tried adding "video=DP-2:1920x1080@80" to kernel parameters and 80Hz did show up in Display settings. But as I expected, just like on xorg before using custom Hsync and Vsync values imported from Adrenalin on my Windows install, issues with Hsync. I can't figure out how to set custom Hsync and Vsync values like with xrandr.

Can anyone help me? Thanks.

This was my first through initially. This is actually where the issues come from. I’m trying to “overclock” my monitor. It’s supported refresh rate is 60Hz but I was able to get it up to 80Hz. On X11 where I was able to set a custom resolution and custom vsync and hsync values with xrandr (as mentioned in the OP).

While it looks like I'm guessing, I'm genuinely trying to help :-)
