Odyssey G9 super ultrawide + 4K projector resolution issues on Fedora 41 Wayland

Ask Fedora

Hey everyone,

I’m having a frustrating problem with my dual display setup on a fresh Fedora 41 installation. I’ve got a Samsung Odyssey G9 super ultrawide monitor hooked up via DisplayPort and a 4K projector connected via HDMI to the same computer. (AMD GPU)

I’m running GNOME on Wayland, and whenever I try to join these displays in the settings, weird resolution stuff happens. The G9 has 5120x1440 resolution and 32:9 aspect ratio and the projector is standard 4K (3840x2160).

I’ve been playing around with different scaling options in the display settings, but nothing seems to work quite right. On the super ultrawide the screen always gets cut off if I select the default resolution. The only fix that seems to work is to switch to a smaller resolution size (3840x1080). But I somehow want to make it work with the right resolution for the screen.

This is a brand new Fedora 41 installation, so I haven’t had a chance to mess anything up yet! :sweat_smile:

Has anyone managed to get a similar setup working properly? Any tips or tricks for handling this issue in GNOME Wayland?

Thanks in advance!

We need to see what you have for hardware and drivers.
Please post the output of inxi -Fzxx as preformatted text so we can have more detailed info.

If you happen to be using an nvidia GPU please also post dnf list --installed \*nvidia\*
