No signal Input or Cable Disconnected or Power Saving

This message comes from the monitor itself.
Meaning no signal of any kind comes from PC.
Issues may be with

  1. Monotor itself
  2. Video Cable
  3. Computer

Here some simple troubleshooting tips.

  • Try to identify what comoponent is at fault, by using other knowly good/tested cable, monitor, computer.

If you use other monitor and everything works - your PC anf video cable fine, but issue with monitor itself.

  • Check simple stuff first.
  1. Power to computer.
  2. Check that video cable connected to both monitor and computer.
