HDMI support tells the graphics driver that the display supports HDMI signals. Without HDMI support, HDMI works like single-link DVI. HDMI support is required for audio. DVI does not carry audio data.

HDMI displays can normally handle DVI signals, but there's no guarantee that DVI displays can handle HDMI signals. Why not plug the receiver directly into the video card? If you need to use a monitor, use the Dell U3011 instead. It can handle 2560x1600 @ 60 Hz with HDMI, but you'll need to add a custom resolution.
