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.

@dredmorbius @aral
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.

@aral BEEFY drive signals. the LCD is enlightened by the GPU's intelligence.
@aral I hear HDMI can carry a network signal as well

@aral This is a wonderful monitor, definitely! 50mA is enough, well, maybe for a seven-segment indicator🙂

@yrabbit @aral don't forget that the host side connector is USB, maybe HDMI has an extension to accept power in this setup

hold my fresh beer with my hdmi fridge !
