Hdmi fix correction suggestion for flex solution

After experimenting with the display issue I have determined the following

Problem Definition:

1. Anytime current draw is sensed from the flex hdmi port before startup has been completed by the internal computer the flex screen boots sideways.

2. Anytime current draw is sensed from the flex hdmi port after startup has
been completed by the internal computer both the flex screen and the connected hdmi monitor display correctly.

Solution:

Inhibit the 5 volts pin 18 from being supplied to the hdmi connector on the flex rear panel until flex startup has completed.

This way it does not matter if the monitor is on or off or if there is an hdmi switch involved or not because without the 5 volts on pin 18 if flex uses pin 19 which is a hot detect it should not matter.

Passive hdmi switches with led indicators do not indicate without a power source until the flex cable is plugged in.

Hopefully this could be implemented with a firmware update depending on how much control flex has with the internal computer os and firmware / hardware.

NOTE

I am not an engineer but I bet if somehow I opened the 5v line on my hdmi port where the flex connects and put a switch there It would be a work around.

Just my observations from my tests.
