Is it possible to change resolution outside of the game?
Currently I can't play Battlefront 2 because my monitor doesn't like the resolution. I have had this problem previously with other games and have been able to fix it by changing the settings with geforce experience, this however doesn't work with battlefront 2 so I was wondering if there is a way that I could change the resolution outside of the game.
With pretty much any PC video game, the resolution you use for the operating system will have impact on the game. So if you want to set to 4K in the game, you'll want to make sure in the OS (presumably Windows) it's set to at least 4K.
I don't understand your comment about GeForce Experience. It sets up SWBF2 fine.
If you want people in this forum to help you further, you'll want to provide more specifics about your configuration. A DXDIAG report might help.
