apex legends resolution
so my computer is on a 1920x1080 resolution. But when i open apex legends, it says 'Failed to CreateGameWindow. Resolution (1280x720) unsupported?'. The problem is im not even on 1280x720 and instead...
Do that. It seems that games default resolution for everyone is 1280x720 and your monitor probably doesnt support it. It should work.
