The HDMI connection on a computer definitely outputs both video and

can output the video and audio from my little laptop to my 65 inch flat
screen TV. :-)

An HDMI input pretty much implies that you have a video capture card
but the DRM hardware in the HDMI adapter makes it pretty useless Most
things that have HDMI out will not talk to them (cable/sat boxes etc).
If you can find an old version of the firmware before they started
enabling the DRM it will work.
