Monitor Shows Message "No Signal/Input Device Detected"

Tags faculty staff

This error is the result of power management settings.

  1. Try to "wake" the machine up by using an input device (e.g. keyboard/mouse movement)
  2. If that fails, the computer froze while in standby and will need to be restarted.
  3. Hold the power button down on the PC for a few seconds.
  4. Once it powers down, the user can immediately power it back on.
  5. Verify that the display works correctly.​ If that fails, make sure the cable going from the monitor to the pc is firmly inserted at both ends.
