I have installed Debian 12 with KDE and two monitors. My main screen is set to 2560x1080 instead of 2560x1440, I would like to add the correct resolution.

Connections are on the onboard Intel graphics, with 2 ports; VGA to HDMI adapter, and DVI to HDMI adapter, so it is possible the screen capabilities are not being detected.

The i915 drivers were auto installed and look like they are running, tho KDE reports that it is using Mesa Intel® HD Graphics 2000. Is this the same thing? I believe this is using Wayland, I’m not familiar with configuring desktop settings for this. Is there an easy way to add a custom resolution?
