Also try the other names for the HDMI port.
I just bought a new Samsung TV <span id="INSERTION_MARKER"><span id="INSERTION_MARKER"><span id="INSERTION_MARKER">model: LN32D450G1 and I want to connect my 5 year old Macbook Pro version 10.6.3 with Snow Leopard OS. I am using a 25 foot hdmi to dvi cable. The television does not recognize the computer and the computer does not recognize the TV as a moniter. What configuration do I need in order for my laptop to display on my TV.
