DisplayPort, abbreviated DP, is a digital audio and video interface created by VESA. Its connections come in two varieties: standard, (shown in the picture) and the smaller Mini DisplayPort. Despite the difference in size, both connector types transmit identical signals.
DisplayPort cables are very similar to high-speed HDMI in terms of bandwidth, but can have a much higher refresh rate at peak resolution (60 Hz versus HDMI's 24 Hz). A DisplayPort to HDMI converter is available to connect a DisplayPort to an HDMI port.| CaseOnline.com
