The efforts of AMD and NVIDIA companies on displayPort interface actively gets accustomed on video cards, and chipset Intel h55 and H57 will make the corresponding ports type general for motherboards. VESA organ last week stated about the specifications Of displayPort 1.2, which determine standard for the new generation interface.
First , in comparison with DisplayPort 1.1a new standard increased the maximum data transmission speed from 10,8 to 21,6 Gbit/s. The support of several independent threads allow the interface displayPort 1.2 to transfer video with sound to several monitors using one cable - both with series connection and with a switchboard. To one port displayPort 1.2 it is possible to connect to two monitors, which reproduce pictures with the size of 2560 X 1600 points with 60 Hz frequency, or four monitors with 1920 X 1200 points. With the use of a single monitor, the supported resolution grows to 3840 X 2400 points, monitor with the support of 120 Hz frequency are supported with resolution up to 2560 X 1600 points.
The capacity of auxiliary channel in the standard displayPort 1.2 increased from 1 to 720 Mbit/s. This allow to transfer via one cable not only video and sound, but also information on USB 2.0 or Ethernet interface. The interface displayPort 1.2 implies reverse compatibility with devices and cables, which support DisplayPort 1.1a.
