is power required to use HDMI?
is the AC power adapter required to use the HDMI port on Macbook pro?
Not for the MBP but the display will have to have its own power. Battery run time will be short though.

Can you expand on your answer. I have a MacBook Pro with a 27 in monitor connected via the HDMI port on the MBP. If I disconnect the power cable with the MBP lid down then the monitor will go off, like in sleep mode. If I leave the MBP lid up so that the display's are mirrored the external display will work on battery.
Not sure how to have the lid closed and on battery and use the monitor as the main display.
