VESA, one of the driving forces behind the DisplayPort standard, has introduced a new version of the interface during the CES. The new version brings us to DisplayPort 1.2, which will now support 3D-signals, Dolby TrueHD and DTS HD audiostreams, as well as USB2.0- or networkdata with speeds of up to 720 Mbit/s.
The new functionality is made possible by the doubled bandwidth of 21,8 Gbit/s, over twice as much as the bandwidth of the current HDMI 1.4 standard, which is specified at 10,2 Gbit/s. This allows for greater resolutions, improved colour depths and increased refresh rates. The maximum resolution has been raised to 3840 x 2400 pixels at 60 Hz, or 2560 x 1600 pixels on a 120 Hz 3D-screen.
At the same time, the new standard is backwards compatible with its predecessor, meaning no new cables or connectors have to be introduced.
