Different aspect ratio same Screen

is 1024x768 the highest 4:3 resolution?
just because this comparison doesn't seem too fair

they should have made it so
tan(FovX/2)*tan(FovY/2)=const
which basically makes what you see equal for all aspect ratios. So the widescreens show more on the side, and 4:3 shows more vertically.

Probably the reason for it becoming wider, but not narrower on widescreen is that the default function for creating a Perspective Projection matrix takes the angle for the Y opening and an aspect ratio. So they did something like "Perspective( 50deg , Width/Height , near , far)"

There is no need to go widescreen at all - widescreen allows you to see more to the left and right, while 4:3 is larger vertically. 4:3 might even be better than wide because your vision is more equally distributed.

it's actually the same vertically

only horizontal view is different

ah i see, yeah 16 has more width.

isn't 16:19 1920x1080 (not 1980x1050)

i wish there were smaller resolutions that were 16
