# How to turn display on and off on Windows IoT?

I've got a Windows IoT UWP app wherein a motion detector will turn the display on if someone is in proximity, and then turn off after a period of no motion detected. The LCD in question is this one.

There are many examples of how to turn an Hdmi display on and off with Linux, but none for Windows.

The closest I've come is to turn it off with: powercfg -change -monitor-timeout-ac 1 which sets the monitor timeout to 1 second.

Nothing I've tried, including powercfg -change -monitor-timeout-ac 0, turns it back on.

Is this possible on Windows IoT (code or command line)?

• Did you find the answer? I am also interested in this. – dnk.nitro Nov 10 '17 at 3:14
• Haven't found anything. Right now am looking at whether I can suspend the PI into S3 or modern standby and wake it from the PIR or wiring a bypass to the manual backlight powerswitch and controlling that from the GPIO. – dkackman Nov 10 '17 at 16:25
