I was playing osu! on 1366X768 in fullscreen with black bars around the game, but after i restarted my pc my game started in 1366x768 but stretched like a borderless fullscreen but i liked it. So the problem is, after i restarted my pc again the resolution changed back to the 1366X768 with black bars and i want the stretched resolution back but idk how to do it .-. btw sry for my terrible english
