Hdmi port device

you have to be more specific.

typically computer hdmi ports are hdmi-out
typically television hdmi ports are hdmi-in

if you are trying to view photos on your pc use the usb to mini-usb cable that came with the camera

if you are trying to view photos on your television then you would have to be specific about what connectors you have. ive seen RCA style hookups but i wouldnt be suprised to see an hdmi one as well. in any case hookup is normally very simple
