I use a timer of 5 minutes for switching off my monitor, and with all other sims I don't have any issue (X-Plane, IL-2, CLOD, IL-2 1946, etc...) but with DCS World yes, when I'm flying the monitor go standby after the 5 minutes. I have tried also ALT+ENTER as suggested to switch to full screen (what? need to do that?? ) but nothing is changed... and yes. I know it's because there is no input from the keyboard/mouse, I can disable the timer in the windows control panel but I wanted to ask if there is a different solution and if happen to somebody else. My OS is Windows 8.1, thank you
