Hi all,
Hopefully someone can help me. I have a prototype where I want to add a touch screen control to the pi.
Now the PI is powered currently using GPIO pins, but I have also tested through the usbc power as well.
I have a external ARZOPA touch screen display (picked up on a black friday deal).

This is connected via

and

Currently this has a usbc to power connector through the 2nd usbc slot (I have disconnected the usbc to usba connector to the pi for the moment whilst troubleshooting).
If I unplug the hdmi, then plug it back in the screen displays the signal for approximately 7-10 seconds and then disappears?
currently my `boot/firmare/config.txt` is;
You can see I also have another display (a projector which is powered itself), this is working though currently turned off to try to debug this screen (this is on a micro HDMI to HDMI cable).
Can anyone point me in the right direction of fixing this? Does it need some kind of HDMI booster?
