HDCP Compatibility

FWIW: After days of exploring specs, posts, blogs, support, and the inner workings of both my Dell XPS 8100 (with nVidia GeForce GTS240 card and ST2310 monitor) and my Sony Bravia KDL-40XBR5...............I could NOT get the TV to work as a computer monitor. That dang "System is not HDCP compatible" warning kept coming up. Finally, I flip-flopped where the monitor's DVI/VGA and the TV's DVI/HDMI cables were connected. VIOLA! Obviously (at least now), one of the graphic card's DVI connection is HDCP compatible and the other one is not.  Again............for what it's worth....................
