My monitor's resolution is 2560x1080, and fullscreen works fine with it then. 1920x1080 fullscreen stretches the game, but it still works.
When I change my resolution to 1920x1080 in Windows 10 and I load up Wizard101, 2560x1080 is still an option in the game for some reason. Trying 1920x1080 fullscreen, the game just makes my entire screen black. If I force close out with alt+f4 and try to reload the game, it creates a 1920x1080 white screen (outer sides black like normal) and makes the sounds, but I get the following error popup.
