The Video Electronics Standards Association or VESA has announced a new digital display interface, dubbed DisplayPort.

This new interface will supplant DVI and VGA connections eventually and its micropacket architecture offers significantly more bandwidth with multi-monitor support over a single cable. Like HDMI, a DisplayPort connection can carry 8-channel 24-bit audio, but also offers a dedicated auxiliary link for control communications of things like panel I/O and microphone connections. There are hundreds of big brand name companies behind the standard that is set to compete with HDMI for desktop and notebook dominance, including the likes of AMD, Intel, NVIDIA, Samsung and Dell.

However, DisplayPort is more likely to co-exist with HDMI, since HDMI is specifically targeted for consumer electronics like set-top boxes, DVD players etc, while DisplayPort was designed from the ground up for computing.

Though we’ve heard through the grapevine that NVIDIA is readying DisplayPort capable graphics cards for sometime early next year, AMD has stepped up with the first DisplayPort-enabled graphics card to hit our test labs.
