Diablo II (original) starts in full-screen mode and changes between any of the modes with ease. Diablo Resurrected starts out in Window mode. Even when it is changed to full screen the taskbar remains at the bottom and if the cursor moves far enough down I find myself outside of the game. I have tried alt+enter. I have tried recommendations from various websites. I am on an Alienware 1070 with an NVIDIA GeForce GTX 1070 graphics card. Right now Full Screen seems to be stuck on the top settings 3840x2160 and the arrow is gone. I can drop down to window mode where I can change to 1920x1080 however switching back to full-screen it goes back to 3840x2160. So frustrating.
Pretty much the exact same issue here. I’m about to try changing desktop resolution before opening the game to see if fullscreen resolution changes that way but pain in the butt.
