[SOLVED] amdgpu 5120x1440

Hello,
I recently got a 32:9 monitor with a maximum resolution of 5120x1440 at 240Hz, with an integrated Radeon 680M video card.
While with Windows (dual boot) I can set the maximum resolution (at 120Hz because I use the HDMI 2.1 port), with Linux I can at most get to 3840x1080 (120Hz).
I use Gnome/Kde with Wayland.
Has anyone solved it?
Thanks

Do you have DislayPort available?

Thanks for the reply, unfortunately the only display port is occupied by the other PC.
Thanks again

It looks like AMD won't be able to fix the HDMI problem anytime soon...
If you consider this solved, please edit the title of your first post and prepend [SOLVED].
