Display actual ratio/display reported ratio mismatch

[2V3EvG4LMJFdRe]

I have a bunch of TVs and displays which I connect through different means to my PC. Some of them run the OS with the wrong ratio and there's no way to change it. So for instance, a 4:3 TV is outputs as 16:10 to the OS, therefore for 4:3 to fill the screen I have to do video-aspect-override=16:10. If the content is not in 4:3, then I have to sort of guess what ratio to force until it looks right.

I'm wondering if there's a better way to go around this problem. There's options like monitoraspect=<ratio> but they don't seem to do anything.

I am such a dumbass, on macOS if you hold option or command while pressing Scaled on the display settings, more options appear.
