There are a lot of use cases where you want a machine to be running constantly but don't want the screen to be on constantly.
I can't put one of these in my bedroom unless I can easily and instantly switch the monitor on/off.
[edit] I have an existing PiTFT which also doesn't have a power button. I can turn it on/off programatically, but still a power button would be highly useful.
[edit2] Can this screen be turned off programatically without turning the Pi off at the same time, if the screen is powering the Pi?
[edit3] Hang on. Is it even possible to turn the screen on/off programatically from the Pi if the Pi is powered separately?
- visualpipe 11y agoYou can by a USB cable with switch on it.
- mike-cardwell 11y agoWhilst that would work, it's less than ideal. I'd need to power the monitor and Pi separately at that point. If turning the screen off prevents that pass-through power capability, that is a poorly thought out design.
- whiskers 11y agoI've just confirmed with the foundation that the display will be controllable from software but the current Raspbian image doesn't have it yet - this will allow you to turn off the screen and backlight while leaving the Pi running. So your use case will be possible!
- mike-cardwell 11y agoThat makes the screen a whole lot more useful to me. I will probably buy one when that happens.
