I have a laptop running Windows 7; I am trying to connect it to my TV, using the HDMI port on my laptop and an AV input on my TV; I have a cable with the corrent ends on it, and I am certain my HDMI port and my TV are both working. The problem seems to be that the Windows 7 "connect to a projector" options do not allow one to use the HDMI port as an output for this purpose; How do I do this?
