Custom UW resolution for regular 16:9 screen?

Hello everyone!

I’m using a 4k 48" TV as a monitor, and want to scale the screen down to 3440x1440 / 21:9 with black bars on the top and bottom. I’ve managed to do this with the AMD Adrenaline software on my Windows partition, but when I tried to create a custom resolution on my EndeavourOS partition with xrandr, the screen just goes black whenever I apply it.

Has anyone here been succesful doing this, or have any tips? Thanks!

You’re using X11 rather than Wayland, right?
What command are you using for xrandr?

HERRAX,

Nope, I’m using Wayland. I went through the steps in this guide: itslinuxfoss.com/set-custom-resolution-using-xran…

Well the method looks correct, but xrandr doesn’t support full wayland, AFAIK. It’s really meant for X11.

I haven’t looked into this myself, but perhaps there’s a newer tool that can get the job done?
