Can't change screen mode (Divinity: Original Sin 2)

Hello, I encounter the following problem. The screen resolution can change, but the mode screen. If you change from Full Screen to any other screen appears black and all. The task Manager does not help, because the cursor stays on the game and not allow anything to press. Please help.

P. S I Have the Definitive Edition
P. S. S In Full Screen, if I turned off the game by alt+tab after you can't log into the game. Have to close through the Manager
