I'm very new to RP and I recently bought a new RP 4 and wanted to use a portable touchscreen monitor with it, but I wanted something bigger than the 7-10" ones I saw. I went for this one after a recommendation of similar screens

Asus ZenScreen

The problem is it has only one usb-c port that functions as both power and video. It didn't seem to be getting enough from the micro HDMI to usb c connector so I got a splitter that separates the two as inputs (micro HDMI to HDMI and usb-c power) which then goes into the screen. All I get is the screen powering on and off in a loop.

They do have Linux drivers but I can't seem to open these, but I've read of people creating their own.

Is there anything I can try to get this to work?

And what is the likely problem here, is it driver related? Or more a case of connection issues?

Thanks for any help!

  • Welcome. Unless the source for the drivers is available you're out of luck; they won't come pre-compiled for the Pi. A quick search online implies the screen needs > 2A, so there is no way you could power it from the Pi. A quick glance at the product page for that splitter implies you are trying to use it backward. Have you actually seen any reports of anyone using this screen successfully? I could not find any...
