Displayport V1.2 To Take Giant Leap Over HDMI

Posted by Soulskill on from the any-old-port-in-the-storm dept.

An anonymous reader writes "With HDMI becoming increasingly common, Displayport has been slow to emerge as a widely used connection interface, but a plethora of new features in the new v1.2 standard could see that change. As well as doubling the data rate of the existing v1.1a standard to 21.6 Gbps, the update allows for multiple monitors to be connected to a single Displayport connector and adds support for transporting USB data at up to 720Mbps, enabling embedded webcams, speakers and USB hubs over a single cable. Ethernet data is also supported. The improved data rate will allow for richer, larger and higher resolution displays, and the new version is also backward compatible with the current display technology, so all the ports, cables and devices will be interchangeable, although they will revert to the lowest common denominator."

    I hate Apple as much as the next guy, but not mentioning them at all in the summary is a bit... crude. Also, here's a list of all the new stuff (taken from http://www.hardmac.com/news/2010/01/11/displayport-1-2-validated).
            * Doubling bandwidth mostly to support 3D: 21.6 Gbits/s.
            * Connect even more monitors from a single DisplayPort. Dedicated hubs should soon be available.
            * As for the HDMI, transport USB data between a computer and a display, supporting Display USB functions such as a webcam and USB hub.
            * Connect to display with 3840 x 2400 resolution at 60Hz, or a 3D display (120Hz) at 2560 x 1600.
            * Audio Copy Protection and category codes
            * High definition audio formats (such as Dolby MAT, DTS HD, all BD formats,etc.)
            * Synchronization assist between audio and video, multiple audio channels, and multiple audio sink devices using Global Time Code (GTC)

      Why yes, you can.

      You can either get a cable, or just the dongle, whichever you prefer.

      One of these days, I am going to flip out. When I flip out, I'll be back in five minutes.

    This problem was solved a few years ago. Look up ClearCurve. They clad the fibre in tiny reflectors that recover the stray signal.

  3. Encoding and decoding for DRM by tepples · · Score: 5, Informative

    HDMI needs additional chips/control circuits on the transmitting and receiving end to deal with encoding and decoding. Display Port is directly compatible with the display panels themselves and as such

    ...can't display motion pictures published by six American companies. Home users who expect to watch high-definition feature films will choose an interconnect that does "encoding and decoding" because the publishers of feature films on high-definition home video demand "encoding and decoding" for digital restrictions management. Sure, DisplayPort 1.1 and later allow for DPCP, but then you lose the advantage of no "encoding and decoding".
