Need help using my portable monitor with a pi 4 (self.sbcs)

I've got a portable monitor that only takes one single USB-C input. The Pi 4 can't deliver enough power to keep it on. The monitor power cycles endlessly when plugged into the pi.

Is there a way I could give it more power somehow?

Usb-c pd injector is one solution. But not a cheap solution.

A powered hub is an option, but you have to make sure it has video passthrough, and these aren't common.

I think you just need to look for one marketed as a “docking station”. They’re definitely more expensive

If the solutions for those AR glasses are anything to go by, you'll need something like a Nubia redmagic (though I found them hard to find in Canada)
