To get the answer to this question, support for HDCP enables the monitor to display HDTV resolution if connected through the HDMI or DVI connector. A monitor without HDCP support, or connected through analog VGA, causes the displayed video to be downgraded in quality to a DVD-like resolution that is less than HDTV.
Hope this helps! Keep me posted for further assistance.
