About this tag
The display sleep tag covers issues related to Windows power-saving features that turn off the display after a period of inactivity. Discussions include conflicts between screen saver timeouts and display sleep timeouts, where the screen saver may be terminated prematurely when the display powers off.

Troubleshooting often involves adjusting power settings and understanding how Windows manages display power states.
