Steam deck stuck on black screen when going into desktop mode after changing resolution

So a few weeks ago Ihad my steamdeck hooked up to my tv and was trying to get it to work, so I changed a display setting, pretty sure it was the resolution though I cant remember what for sure. Now it's just a black screen when I go to desktop mode and Idk how to fix it. Hooking it back up to a monitor or tv doesnt work now. Is there any way to fix this?
