Still having an issue with startup.
The computer won't start unless I plug an hdmi cable in the hdmi out port of the HP AIO 34 and connect this to an hdmi port on different computer that is on and working. If I connect from HP AIO HDMI In - the the AIO works as a monitor and I see a duplicate of the different computer.
Computer mode?
TV mode?
Any suggestions of what to do to et the AIO to start by itself please?
