I had excellent luck by using a dual (or more) output USB power supply with separate cables for the display and the pi. I have a 7" screen, RPI3 and HiFiBerry RCA DAC with no issue. The power supply I am using came from Amazon and it is a Ravpower 4 port travel wall charger with 2.4a capable output on each port, 8 amp total.
I use one cable to the pi and DAC and one to the 7" display. This was after a lot of trial and disappointment on supposedly 3 amp power supplies.

Can I go home now? ------------------------------------------------------------------------ Howard Passman's Profile: http://forums.slimdevices.com/member.php?userid=16674 View this thread: http://forums.slimdevices.com/showthread.php?t=103330 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
