Using the BP node “Get Supported Fullscreen Resolutions” I only get a maximum of 1920 x 1080. Anyone else have this problem. You might say, just override it, enter a higher value. I tried that, it just made the gui out of sync where the mouse wasn’t at the correct location. Considering the monitor has no such issue with any game and is a desktop 4k I think there must be some way to fix it in unreal, any ideas?
