OK, WTF? I just discovered that an HDMI cable connected to a USB-C port on my computer can power the tiny Lilliput HDMI monitor that normally needs/has a power adapter. WTF? How is it powering it over HDMI? *looks around the room in fear*

@aral Ok, I've had cursed usb configs before... but that's a new one on me. wow.

@feonixrift Yeah, imagine my surprise when I realised the adapter wasn’t plugged in and the screen was still on.

DVD player requiring double USB power... plugged into transformer laptop with one USB plug, the other USB plugged into a power converter. Transformer laptop plugged via a USB into a 9v charger atop same converter. Converter plugged into power strip. Everything working fine... power strip is not in the wall.
