I use teamviewer a lot and I want to know current status of my monitor. Is there a command or software to check if a computer screen is on or off. Operating system is Windows 7.

  • The status of the remote host machine's monitor? This isn't really something Windows is aware of, and there isn't exactly, an API that exists. – Ramhound Jun 28 '16 at 23:54
  • Of course it doesn't matter Teamviewer already has a [solution]](superuser.com/questions/440148/…) for you – Ramhound Jun 28 '16 at 23:55
  1. Right Click the computer you want to edit

2.Click Properties

3.Click Advanced (lower left)

4.Click Drop Down under Remote Input (bottom right)

5.Select "Disable Remote Input and Show Black Screen"

6.Log into remote computer from another Desktop edition of TeamViewer and accept the video driver TeamViewer offers


Try to run following command to query the monitor status: wmic path win32_desktopmonitor GET Availability

3 means Running/Full Power 8 means off

but based on my experience, not all monitor supports this API, you can check it on your pc.
