DisplayPort v1.2

Video Electronics Standards Association (VESA) has approved the DisplayPort v1.2. In addition to doubling the standard data rate to 21.6 Gbps v1.1a, this update allows multiple monitors connected to a DisplayPort connector and adding support for USB pass data at speeds up to 720MBps. This means, webcam, speakers and USB hub can be connected in one cable. Ethernet data were included in his support.


To reach a speed of 21.6 Gbps, the data rate per lane at the four-lane has doubled from 2.7 Gbps to 5.4 Gbps. For a single display, this allows a display with a resolution of 3840x2400 at 60Hz reached, or four monitors at 1920 x 1200, or 3D display at 120Hz and 2560x1600 which can effectively and simultaneously use the two streams.

The rate has been enhanced data display that allows a richer, bigger, and higher resolution. This new version is also compatible with existing display technologies now. Ports, cables, and devices were interchangeable, although, of course, will come down to the lowest version.

"DisplayPort Version v1.2 offers a range of benefits and capabilities that can not be served by other standards. This is completely backwards compatible with DisplayPort v1.1a and do not need cable or a new device, which can become the industry standard choice," said Bill Lempesis (Executive Director, VESA).

As a connection interface that is widely used, slow adposi compared DisplayPort HDMI. But according to this Lempesis DisplayPort 1.2 standard truly open multimedia interconnection, flexible, and "quickly penetrated consumer electronics applications."

DisplayPort v1.2 also provides enhanced audio, including multiple channels, video synchronization assistance and support for high definition audio formats like Dolby MAT, DTS HD, Blu-Ray and standard DRA from China, as well as the category codes and copy protection RIAA Digital Restrictions Management ( DRM).

For those who want to join the 3D, available repair support for Full HD display Stereoscopic 3D, which provides full HD images at 120 frames-per-second for each eye, in any 3D format you like. These include field sequential, side by side, pixel interleaved, dual interface, and Stacked.

Now we wait for the presence of devices that implement the new features are.
