[Hidden-tech] HDMI adapter needed

Hi Christine,

Generally you get that message with a USB device. I've never see it with a
DisplayPort adapter, although it could happen if a Thunderbolt adapter is
used when the port is DisplayPort only (they have the same connection). If
you plug in the laptop to AC power, the message may go away. Another
possibility would be the device itself. Can you give us a link to the
adapter you're using?

best,
Zach

Analog audio (headphone jack) of the laptop to get the audio.

too much power. I don’t understand that message.
