title: How to lock Android screen via ADB?
body: <p>Is there a way to lock the Android screen via the ADB? </p>
  
  <p>I find ways to lock the display in an apk, but I want to lock the screen from the PC via ADB, to simulate a display timeout, without having to wait for the timeout. </p>
  
  <p>Is it possible to do this?</p>
  
  <p>Thanks,
  Diane</p>
