I had gotten my son the Kano Kit a few years ago. He didn’t take to it as I had hoped and he just put everything on his shelf to collect dust. Recently I was was looking to buy a small portable monitor to use as a 2nd screen for my laptop and I figured that I could just use his old Kano Screen. When I powered it up with the pi still attached the screen worked fine. Then I just changed the HDMI from the pi to my laptop and I got “No Signal” followed by the green LED turning red.
So I plugged a different pi I had, running LibreELEC, into it and it worked fine again.
Is there a way to make it work as a usb powered portable monitor for any hdmi video source?
