I recently moved to a 4k screen, coming from an ultrawide. On my ultrawide, the FOV was calculated correctly, according to a 21:9 aspect ratio. With the one i have now, it straight up... does not work.

It hapens with any option i set, and it happens with any game. tested with.. siege and dying light 2 and mass effect.

it really butchers games that have a sensitivity that is affected by FOV, too, since the FOV calculation is wildly wrong so is the sensitivity.

Enter the correct resolution

The calculator tries to auto-detect your resolution, but for some reason your browser is reporting 1943x2087, which is definitely not correct.

Seems to not occur on other browsers. might have to do with hardware acceleration being disabled.
