A faulty wire could certainly explain it, as well as a bugged clone can - might be both. Anyway, not stating you need an external supply, but I indeed did with this setup. Have you measured the current draw on the display?

I'm really not sure, but it might be related to the fact that I was using a nano clone (not genuine arduino), which might have a different voltage regulator, or maybe a partly broken one? I'm also considering if the lack of pull-up resistors on the i2c-line could be the reason, even thought when I changed PSU it worked fine.
