ATI could do HDMI X1900XTX
 

ATI SAYS cards based on its R580 chips - marketed as thr Radeon X1900XTX - could sport an HDMI (High-Definition Multimedia Interface) if its partners chose to implement it.

ATI actually said that you can do HDMI via DVI but mind me that would not be the full HDMI, as it would transfer video only.
