Dell Laptop communicating with Optoma GT700 Projector

I have a new Dell laptop with windows 7 and am trying to use a new (double whammy) Optoma GT700 projector. Tried using the HDMI connection and received a grainy image. Using VGA cables, it is better, but we want the HD + audio, rather than VGA + composite audio. Anyway, I tried the normal fixes...screen distance, focus, adjusting the projector and laptop settings to different resolutions, adjusting the two-screen options using the Nvidia desktop controller, and am at my wits end.

Any suggestions on why the HDMI connection would be worse than the VGA between the laptop and projector?

Thanks,

 

Bob
