DisplayPort is a digital display interface technology introduced to reduce display complexity and accelerate the adoption of secure signals technology for HD video display and transfer with optional digital content protection capability.


Since replacing other display technologies such as DVI, LVDS and VGA, DisplayPort has become more popular with manufacturers as a leading digital display technology. DisplayPort can also be used in applications where connector space is limited for better performance and high resolution than the standard cables.

Best of all, the flexibility of DisplayPort allows compatibility with older application models through dongle of adaptor connection. You are not required to replace your old applications; you simply need to validate DisplayPort related technologies for interoperability performance. For more information, please refer DisplayPort website.
