my device has a 4090 Nivida graphic card 32 GB ram, 2 TB hard drive and an i9 processor . it's less then 4 month old. and the games started me at 720p and still had this issue.
Viewing post in why is the corners going off screen
Literally none of these matter for the SCREEN size.
What's the size of your monitor and what kind up upscaling are you using?
If you're playing on a laptop size screen you obviously can't use 1080p size which requires 22-24 inches at least.
Also keep in mind that unity might still clip at the lowest size so you're better off with one bigger than the requirement and then play windowed instead of full screen.
