I would like to build myself a portable monitor and wonder if it is possible then connect the monitor via USB to my laptop and at the same time to provide it with power? Alternatively, 2 USB ports for image / power would be interesting if it does not work at the same time.
As a display, I wanted to use either a 15 "1080p laptop display or a 10" tablet display.
That would be possible if you manage to keep the power consumption of the display below 5 watts.
