Have you tried supplying from a battery/powerbank?
or could it also be a diaplay issue?

Yeah tried to use power bank
Sadly it only support c interface
Wonder mv is not support any C related PD interface
It could be issue, but works well with PC usb port ( low ampere)
Not familiar with this device, but it said it's low power consumption, and I've had some of those low power devices that draw so little the power bank didn't recognize it.
Maybe try 3.3V?
