The Video Electronics Standards Association (VESA) announced today that it’s introducing the latest DisplayPort technology that brings support for upcoming 5K monitors and more. DisplayPort 1.3 for audio and video increases the standard to a maximum link bandwidth of 32.4 Gbps and as a result supports 5K displays with resolutions of 5120 x 2880 on a single cable without compression methods. In addition, users will notice enhanced performance for 4K displays in multi-monitor setups over a single DisplayPort connection:
The increased bandwidth enables higher resolution monitors, including recently announced 5K monitors (with pixel resolutions of 5120 x 2880) using a single DisplayPort cable without the use of compression. It will also enable higher resolutions when driving multiple monitors through a single connection using DisplayPorts Multi-Stream feature, such as the use of two 4K UHD monitors, each with a pixel resolution of 3840 x 2160, when using VESA Coordinated Video Timing.
The timing of the announcement is notable as a new crop of 5K displays are about to hit market and 4K displays become more affordable. Dell recently announced its first 5K monitor coming soon to consumers, while Apple is rumoured to be working on either a new iMac and or monitor that is expected to sport 5K resolution. Here’s what else you can expect from DisplayPort 1.3:
It further refines protocols that enable DisplayPort to share a single cable with other data types. With its higher 8.1 Gbps per-lane link rate, DisplayPort 1.3 can support a single UHD monitor with 60Hz refresh and 24-bit color over two lanes, while assigning the remaining two lanes to increase capacity for alternate data types, such as SuperSpeed USB data, as allowed in DockPort. DisplayPort is the A/V transport standard used by DockPort, Thunderbolt and other wired and wireless multi-function interface standards… DisplayPort 1.3 adds support for HDCP 2.2 and HDMI 2.0 with CEC (Consumer Electronics Control), which enhances DisplayPorts utility for television applications, including 4K video with copy protection. The new standard adds support for the 4:2:0 pixel structure, a video format commonly used on consumer digital television interfaces, which enables support for future 8K x 4K displays.
We’d expect to see new DisplayPort to DisplayPort 1.3 cables that will work nicely for powering new 4K and 5K displays over a Thunderbolt input on newer Macs. The new standard will continue, however, to support conversion to VGA, DVI and HDMI. The DisplayPort 1.3 standard is available now for companies interested in building products with it.
