DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). The interface is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to carry audio, USB, and other forms of data. DisplayPort is backwards compatible with VGA, DVI and HDMI through the use of passive and active adapters.Today, the VGA analog interface is used for high definition video, including resolutions of 1080p and higher.4K UHD is a resolution of 3840 pixels 2160 lines (8.3 megapixels, aspect ratio 16:9) and is one of the two resolutions of ultra high definition television targeted towards consumer television. UHD has twice the horizontal and vertical resolution of the 1080p HDTV format, with four times as many pixels overall.This DisplayPort cables feature a small USB-sized latching connector, two-way display connectivity, higher performance than dual link DVI at 10.8 Gigabits per second, and a unique micro-packet architecture that enables new display features.Feature:This converter can only pass signal from DisplayPort to VGA port.
