DisplayPort does true 4K video….plus other stuff….

DCinema, DisplayPort, Video
Well, it's taken a bit of time, but I think with the announcement of DP1.2 specs last December, the specs (and hopefully soon the vendors) are ready for True Digital Cinema home implementation. The DisplayPort connector supports 1, 2, or 4 data pairs in a main link that also carries clock and optional audio signals, each with a symbol rate of 1.62, 2.7, or 5.4 Gbit/s. The video signal path supports 6 to 16 bits per color channel. This allows the updated DisplayPort 1.2 specification to drive 4K x 2K display (3840x2160) with 30 bits per pixel and 3D over a single 2m cable.DP 1.2 supports a maximum of 5.4Gbps per lane, with 4 lanes providing a whopping 21.6Gbps throughput, more than enough for 10-bit 4xHD resolution (3840x2160).

Samsung: First LCD display to use DisplayPort Interface

DCinema, DisplayPort
So we've been waiting for this for a while now. In Digital Cinema applications display technology throughput has always been a problem. Pumping ~10Gb/s of data to a screen is an issue, be it a projector and/or monitor. There have been a number of "hacks" to get these types of setups working (Dual or Quad DVI/HDMI ports). The problem usually is the seam. It is very hard to sync four DVI output chips properly and even harder to display the pixel information back on the screen (inside the projector/monitor).DisplayPort technology is one attempt to solve this problem:The DisplayPort connector supports 1 to 4 data pairs in a Main Link that also carries audio and clock signals, each with a transfer rate of 1.62 or 2.7 gigabits per second (Gbit/s). The…
