The DisplayPort 1.3 paves the way for 5K or 8K screens

The Video Electronics Standards Association (VESA) announced yesterday the availability of DisplayPort 1.3, which opens the way to the said screens 5K.

Four years after version 1.2, DisplayPort 1.3 further enhances bandwidth. If it does not double, as was the case until now, it still increases by 50% and goes from 21.6 to 32.4 Gb / s. The new version carries the flow of each of the four lines to 8.1 Gb / s, which, surplus (overhead) Removed, allows the transmission of 25.92 Gb / s uncompressed video.

Such bandwidth makes it possible to connect a monitor said 5K (5120 x 2880 pixels or 15 million pixels) with a single link DisplayPort, without using compression. These screens? which display four times the definition WQHD (2560 x 1440 pixels), and almost double the Ultra HD (3840 x 2160 pixels is 8 million pixels)? claim otherwise aggregating two DisplayPort 1.2 connections. It allows otherwise connect two Ultra HD displays to a single output, through the Multi-Stream function.

In comparison, launched the HDMI 2.0 a year ago delivers 18 Gb / s and allows only connect one Ultra HD screen at 60Hz.

DisplayPort 1.3 also introduces support subsampling color 4: 2: 0, with which each pixel does not receive own color information, which opens the way for said screens 8K (7680 x 5760 pixels) . It finally brings support for HDCP 2.2? the latest protection standard to date, which will likely be required to show some Ultra HD programs? and HDMI 2.0 with CEC.

The standard DisplayPort 1.3 is available to manufacturers who can now market screens or with sources of such inputs / outputs.
