Any shortcut or site to make screen black without turning monitor off?
Teaching online night classes and sometimes need to kill all light from my screen instantly (students with photosensitivity). Windows “Turn off display” is too slow. Any faster method?

I keep a bookmark that instantly makes my screen black: make screen black One click → F11 → total darkness in under 2 seconds. No sleep mode, no delay, computer stays fully awake for chat and controls. When the student is ready I just Esc and continue. Simple, free, lifesaver for light-sensitive participants.
