DisplayPort Connector Closeup

Approved at the end of 2009 along with DisplayPort 1.2, this standard is a significant improvement over the previous version and it doubles of the effective bandwidth to 17.28 Gbit/s, which allows increased resolutions, higher refresh rates, and greater color depth. This is the most common standard, used by the vast majority of video cards in 2014.

The data bandwidth represent the maximum information (in gigabytes per seconds) each version of DisplayPort can send to the output. Because of this shared bandwidth, it is possible to connect many monitors of different make, model, resolution and refresh rate on each cable.

The total bandwidth of High Bit Rate 2 connections is 21.6 Gbit/s, the Video Data Rate being 17.28 Gbit/s.

Note: Because it was introduced along with DisplayPort version 1.2, which also added the new Multi-Stream Transport technologies, it is now possible to connect more monitors on the same bandwidth, each with their own resolution and refresh rates.

In this mode, you'll be able to connect monitors with these resolutions on one DisplayPort 1.2 output:
