Solutions

Solution 1: Configure Screensaver Settings

Solution 2: Check for Input Devices Preventing Idle

1Some mice, gamepads, or drawing tablets send tiny movements

3Wireless mice on reflective surfaces can cause phantom movements
4Gaming mice with high polling rates may keep the system "active"
5Check: Device Manager → Mice → Properties → Power Management
6Also check if any gamepad/controller is plugged in with a drifting stick

1If "Turn off display" is set to LESS time than the screensaver wait:
2The display turns off before the screensaver can start
3Open Control Panel → Power Options → Change plan settings
4Set "Turn off the display" to a higher value than your screensaver wait time
5Example: Screensaver = 10 min, Display off = 15 min
6Or set "Turn off the display" to Never and let the screensaver handle it
