My purpose is to turn off the monitor when I run the computer remotely, to save energy and protect privacy. However, after disabling the "Generic PnP Monitor" in Device Manager, the monitor is still on (the image).

I thought by disabling the 'Generic PnP Monitor', Windows should stop sending signals to the monitor, am I wrong about that? btw, it seems the uninstall function also doesn't help.

I just want it off when I run the computer remotely, so I don't have access the power button.

The system is Win10.

Thanks in advance!

Case 1: You have 2 monitors, you want to turn one of them off.
Easiest way to do this is via Settings:

  1. Open Settings, Go to System > Display > Multiple Displays > Advanced Display Settings
  2. Select the display, scroll to bottom, turn it off

Case 2: You want to disable EVERY display you have.
I prefer you do it using a .BAT:

  1. Open notepad,
  2. Paste this code and save as a .bat:
powershell (Add-Type '[DllImport(\"user32.dll\")]^public static extern int SendMessage(int hWnd, int hMsg, int wParam, int lParam);' -Name a -Pas)::SendMessage(-1,0x0112,0xF170,2)
  1. Run it (as admin)

As for why does your monitor still works after you disabled Generic PnP monitor, first thing: This isn't the right way. Second: I'm not exactly sure why, but I think that windows detect Hardware changes and automatically reinstall essential drivers. I think I read this somewhere, But right now, I cannot remember.
