While most consumer electronics devices with DVI connectors will be HDCP compliant, not all computer devices are. So make sure that any computer devices you connect with this cable is HDCP compliant. This pertains to projectors, computer monitors and computer graphics cards.
Q1: Why this cable can not be dual link?
While both HDMI and DVI are able to support extended bandwidth signals, they do it in two totally different ways. HDMI increases bandwidth on the exisiting conduits while DVI takes a double pipe approach referred as dual link. In other words DVI breaks the signal down into two separate sets of signals by adding 6 extra pins. HDMI has 19 pin and DVI single link has the same number of corresponding pins. There are no extra pins in HDMI to accomodate the extra pins in DVI dual link.
