I have an RPi4 and a Viewsonic TD1655 touchscreen, which has two USB C ports and can pass through power.
Currently, in order to use the screen I need to use a seperate power adapter to power the screen, a data cable (USB A - USB C) and hdmi cable between the devices.
I travel a lot so I am trying to streamline my setup to use one power supply, with a usb C cable between pi and screen for power AND data, and an HDMI cable.
If I use the RPi5 power supply, it will do 5v at 5a. This is enough to run the screen (5v3a) and the pi (with reduced usb power output).
In trying to get power and data happening through the USBC port of the pi, I have tried adding:to the /boot/config.txt without success, so I next tried:but still no bueno.
Any ideas?
