Hello Lemmy, hello Linux users!

I am trying to get into all this open source jazz and finding a way to give a second life to this god awful monitor/tv. It’s from a company I’ve never heard of before called OCEANIC, and it has plastic borders that actually just obstruct the sides of the screen, which means it has a letterbox-ed view of everything one would do on a computer.

I would love to get a suggestion on how I could possibly solve this problem! Resolutions proposed in the settings don’t work but maybe a custom one is needed?
