DisplayPort
DisplayPort is a connection similar to the HDMI in the respect that it can also carry, on a single cable, digital video and digital audio, supports eight channels, has 24-bit resolution and a 192 kHz sampling rate, just like HDMI. While HDMI is targeted more towards consumer electronics, DisplayPort is targeted more to computers. Another important difference between the two is that the DisplayPort is a royalty-free standard, while manufacturers that want to use the HDMI connection must pay a royalty fee for each product sold. It supports its own copy-protection protocol, DPCP (DisplayPort Content Protection), and since its 1.1 version, also supports the HDCP protocol. It supports 4K resolution (4096 x 2160) and 3D video, just like HDMI 1.4. DisplayPort is very similar to HDMI 1.4, except that HDMI 1.4 supports a Fast Ethernet connection. On the other hand, DisplayPort has a bandwidth of up to 21.6 Gbps, while the bandwidth of HDMI 1.3 and 1.4 is 10.2 Gbps, leaving “space” for future features and resolutions.
One advantage of DisplayPort over HDMI is that it allows the installation of up to three video monitors to each port. In order to do that, you will need to use a DisplayPort hub connected to the video card, and the video monitors will be connected to the hub. Optionally, you can use a video monitor that has this component embedded, so you connect this monitor to the video card and the other two monitors to the ports available on the first monitor.
There is a miniature version of the DisplayPort connector, called Mini DisplayPort or simply Mini DP.
