DisplayPort 1.2 Confirmed, Blows Away HDMI 1.4

Been a long time defender of HDMI? You may find your position has just become that little bit more untenable...

The Video Electronics Standards Association (VESA to you and I) has this week formalised Displayport 1.2 and it is kicking some HDMI ass. Fulfilling its long time aim, v1.2 finally brings multi-monitor support from a single plug. In theory this means one graphics card running a series of daisy chained displays all from a single output. Yep, tasty.

The limit on this is up to four monitors at 1920 x 1200 pixels, a pair at 2560 x 1600 or - if you're on some kind of mega-display - a single display at 3840 x 2400 which all sounds pretty good to me. That isn't then end of the story, however, since v1.2 will also support Full HD at 120 frames per channel 3D, a 21.6Gbps data rate and - wait for it - bidirectional USB data at up to 480Mbps.

This last point is killer since devices connected by a DisplayPort 1.2 cable can work like ultra fast USB hubs powering integrated webcams, memory keys and speakers. Even 10/100 Ethernet data transfer is possible over it.

"Displayport Version v1.2 offers a complete set of benefits and capabilities that no other standard can provide," proclaimed VESA executive director Bill Lempesis. "It is completely backward compatible with DisplayPort v1.1a and requires no new cables or other equipment, making it the standard of choice across the industry."

Of course, despite each and every one of these benefits, HDMI is the industry standard so it will take some shifting. That said, what always gets companies talking is price and - unlike HDMI - DisplayPort is a completely open standard so manufacturers can use it without paying royalties. And who doesn't like saving money?

Eat your heart out HDMI 1.4...
