While DVI, D-sub, S-video are the most common interfaces which are used on TV and PC monitors, the market wants to have a better solution which provides not only high quality video signal but also pure audio signal. To meet the market’s demand, the first solution is HDMI (High definition multimedia interface). However, due to the high cost of certification, DisplayPort becomes the alternative solution to transfer audio and video at once but needs lower cost.

DisplayPort is put forth by VESA (the Video Electronics Standards Association) in 2006 and is designed to feature the smaller connectors, easier set up, thinner cables…everything that you can imagine. The DisplayPort version 1.1a supports maximum of 10.8 Gbit/s data rate and WQXGA (2560×1600) resolution over a 3 meter cable as well as 7.1 Channel audio. It also includes HDCP copy protection to work with the most popular Blu-ray video content. Furthermore, the connector of DisplayPort is similar to the USB connector which is easier to be inserted and removed from the interface.

The most important advantage of DisplayPort is “license-free, royalty-free”, and that’s why lots of companies like it. Ironically, the current biggest problem is lack of supported devices. There are only two monitors on the market which support DisplayPort interface. One is UltraSharp 3008WFP from Dell, and another one is UltraSharp 2408WFP from Dell as well.
