As you can see, something is wrong. I haven’t had this issue happen on any of my other systems. I use the Nvidia drivers, if that helps. I’ve looked through many different posts here, on Reddit, and other forums and none of them have been able to give me a straight answer on what exactly to do. Some say you need to edit something called "edid.bin, others say you just need to run these very specific xrandr commands that involve measuring your screen, and others say you only need to adjust the dpi slider in settings. I don’t have a ruler, nor do I think that having one could help anyway, so I’m just lost. Do I just need to deal with it? This really sucks.
EDIT: My laptop is an Acer Predator g9-793 and it runs at 1080p.
