The Video Electronics Standards Association (VESA) has upgraded the interface for DisplayPort to version 1.2, doubling the data rate from v1.1 and providing support for multiple monitors.
Data transfer rate is now 21.6 Gbps, allowing for higher display resolution, color depth, refresh rates, and 3D playback.
Says PCMag: DisplayPort v1.2 supports "multi-streaming"—the ability to transport multiple independent uncompressed display and audio streams over a single cable, supporting protected content and high performance applications such as 3D gaming. This enables the use of multiple monitors connected by cable in a daisy chain or hub configuration. Whereas the current Display v1.1a standard can support one 2,560-by-1,600 monitor at 60Hz, DisplayPort v1.2 can support two such monitors with one cable, or four 1,920-by-1,200 monitors. Many other combinations are possible, including multiple video sources, multiple displays (even at different resolutions) and multiple audio speakers.
The update is compatible with all existing DP systems and cables.
Additionally, v1.2 adds Audio Copy Protection, Dolby MAT, DTS HD, all Blu-ray formats, and the DRA standard from China support.
Adds the source, "DisplayPort v1.2 also includes improved support for full-HD 3D stereoscopic displays: lifelike motion using up to 240 frames per second (fps) in full HD, providing 120 fps for each eye; 3D stereo transmission format support; field sequential, side by side, pixel interleaved, dual interface, and stacked; 3D Stereo display capability declaration; mono, stereo, and 3D glasses."
