I know, the title is a little deceptive. Let me elaborate.
I use 1600x1200 on an ultrawide monitor. It stretches across my monitor. Even if I change my resolution to 1920x1080 in Nvidia control panel, it still does it. I’m trying to get Overwatch to think I’m using a regular monitor instead of an ultrawide so the game isn’t stretched across my monitor. I want blackbars on both sides of my game. (I know, it’s a weird thing to actually want. I’m just use to 1920x1080 and not an ultrawide.)
I know it’s a weird resolution, it’s just what I use.
