As far as I understand DVI pushes analog and digital over a DVI-I Cable, certain pins are used for certain signals.<br><br>That being said, I have a 7300GS the is connected with a DVI-D to HDMI cable and is playing 1080p(1920x1080) just fine. As far as I can tell with the Specs online, it was a driver issue that prevented this resolution when the cards first came out, but that is no longer the case.
