I would like to add a hd-port to my emachine T1641-02w. What is compatible for the computer?

If it is an hd compatible tv the is has to have either an hdmi port or a dvi port. Our old projection tv was hd but before the current hdmi format so we had to use an hdmi to dvi conversion cable. If it doesn't have either of these then it probably isn't hd compatible.
