ELI5: Why do Gamma settings in video games ask you to adjust the brightness until a logo or an image is barely visible?
I've seen a lot of games do the "adjust until the image on the left is barely visible" screen with 3 images of varying brightness. Why do games use this specific approach? I know the Gamma setting is for the loads of different screens one might have, but why the "until this is barely visible"? #education
