VESA has officially launched its DisplayPort 1.2 standard, announced during the CES conference. The v1.2 revision brings supports for 3D-signals, Dolby TrueHD and DTS HD. Compared to the last revision v1.1a, the available bandwidth has doubled from 10,8 Gbit/s to 21,6 Gbit/s. This means the latest version of the interface is capable of linking up to four monitors with a 1920x1200 pixel resolution. Thanks to the support for dual-channel communication, USB hubs and other USB devices can also be connected with a DisplayPort cable. The maximum transferspeed while doing so is specified at 720 Mbit/s, more than enough for a USB 2.0 connection.
DisplayPort also improves Audio Copy Protection (ACP) and supports the Dolby MAT, DTS HD and Blu-ray audio formats. The Chinese DRA standard is also supported with the new version. In terms of video, up to 240 frams per second can be transmitted in a Full HD resolution, providing each eye with 120 frames per second while using Full HD 3D stereoscopic images.
The v1.2 standard is also compatible with earlier DisplayPort revisions. To use the new features of the v1.2 revision, it's required that all devices support it.
