No Signal HDMI keeps dropping out
Hi all, I am having an issue with a few AP4-75-02 flat panels. They work for a while using a laptop on HDMI 1 and running the Android box on HDMI 2. We are having an issue with the flat panel losing the HDMI 1 signal. Sometimes its after running Microsoft Powerpoint slide shows. We either get the "No Signal" or the home screen of the android box appears on HDMI 1. If its the No Signal we have to shut everything down and start it all up again. If it is the home screen you have to switch between HDMI 2 (which the android is connected to) then back to HDMI 1. I have update all the boards and still getting this issue. I have also tried them on different HDMI ports and different laptops.
