Trying to find a good 7 to 10 inch touch screen that is higher resolution then the 800x480 That will still use the MIPI DSI port.
If that’s not really applicable a good 10 inch hdmi+usb touchscreen.

You are awesome, I was getting the feeling I was going to have to go the hdmi/usb route. Which is ok, I could probably slot in a powered usb splitter to add more ports. So now I need design a prototype and 3D print the case.
