Another Noob Question

[Ortnit]

I experience something similar with the power saving option that turns off my monitor after a set amount of time. But just moving the mouse or hitting any key reactivates the monitor.

alt+enter will make you go Fullscreen/Exit Fullscreen and that sometimes crashes the game, at least on my PCs. But it could help.

I would check the energy options for my monitor and set them for a longer time.
