There are a lot of use cases where you want a machine to be running constantly but don&#x27;t want the screen to be on constantly.<p>I can&#x27;t put one of these in my bedroom unless I can easily and instantly switch the monitor on&#x2F;off.<p>[edit] I have an existing PiTFT which also doesn&#x27;t have a power button. I can turn it on&#x2F;off programatically, but still a power button would be highly useful.<p>[edit2] Can this screen be turned off programatically without turning the Pi off at the same time, if the screen is powering the Pi?<p>[edit3] Hang on. Is it even possible to turn the screen on&#x2F;off programatically from the Pi if the Pi is powered separately?
