The DVI over CAT5e/6 Transmitter and Receiver, using a DVI Extender over single CAT5e/6 cable, allows uncompressed video and audio from a DVI source to be transmitted over distances of up to 60m to a DVI or HD display (provided the HD display has DVI output). This device is useful for a number of applications, including home entertainment, lecture displays, retail sales or commercial advertising displays, or business/educational presentations.
