DisplayPort is the latest display interface standard available for replacing the existing LVDS, VGA and DVI interfaces currently used across personal computer industry.
Devang Sachadev, a technical marketing engineer at Nvidia and a director of the association, noted DisplayPort is a common interface across internal and external display connections that significantly improves performance of audio and video over one cable and allows for sleeker form factor in notebooks and LCD displays.
Sachdev said with increased support for DisplayPort technology of the PC industry, VESTA member number has increased at 20% rate over the past four years to current some 180 corporations. He noted that corporate members set compliance-test standard for the technology in addition to drafting up codes for the latest display technology and other crucial technologies-related DisplayPort. The related technologies include MDDI standard and 1.4 version of EDID standard.
Craig Wiley, a senior marketing manager of Parade Technologies Ltd. and a VESA member, pointed out that compared with VGA and DVI standards, DisplayPort delivers better display resolution, richer colors, and faster refresh frequency. He added that with these merits, the powerful next-generation PC hardware and software would be able to further upgrade consumers` visual experience.
Like HDMI interface, DisplayPort can transmit audio signal and adopts HDCP content protection mechanism. The difference is DisplayPort is a free, open standard promoted by PC makers. Also, DisplayPort is a scalable standard, allowing it to beam signals through one, two or four data channels on receiver or transmitter.
DisplayPort supports two transmission rates, with each channel sending data at 1.62Gbps or 2.7Gbps.
