ADB shell command to refresh android phone screen

Question

I modified android phone hdmi output properties using ADB commands below

adb shell setprop persist.demo.rotationlock false
adb shell setprop persist.demo.singledisplay true

In order to see the change, I will have to do either one of the following.

• turn off phone screen, then turn on phone screen.
• restart the phone or tv
• unplug the phone to monitor, then plug the phone to monitor.

What I want: Is there any command to do a quick reload/reset/refresh phone screen or video output connection? so I don't have to do any of the above to see the change.

Any help is appreciated

Answer 1

• To "turn off phone screen, then turn on phone screen":

  adb shell input keyevent 26

  Run the above command twice. 26 is the keyevent code for power button.

• To "restart phone":

  adb reboot
