Is there any way to make Forza 7 compatible to 16:10 monitors? Would say, to show pixel to pixel, without resizing nor distorting, at 1920x1200 res?
Try choosing “native resolution” in the video options.
Select Native Resolution in the Video settings. Also keep in mind that the menus are locked at 16:9 but it will switch to your native aspect ratio when in a race.
