It is official, DisplayPort 1.3 has finished VESA approval and should be hitting the streets in the near future. Freesync support came with 1.2a which is why it was not mentioned, however DockPort has been enhanced with the higher 8.1 Gbps link rate for each of the four lanes present which means you can support a 4k monitor using two of those lanes, leaving the other two available for USB, audio or even power.
This also means that 4k and even 5k monitors can function over a single DisplayPort 1.3 cable without any compression and with the use of VESA's Coordinated Video Timing you can have a pair of 4k monitors function in multi-monitor mode … assuming you have the graphical horsepower to run 7680 x 2160. It is rather impressive to see this jump to 32.4 Gbps combined link rate that can deliver 25.92 Gbps of uncompressed video data.
Newark, CA (15 September 2014) The Video Electronics Standards Association (VESA) announced the release of the DisplayPort 1.3 audio / video (A/V) standard. An update to the widely used DisplayPort 1.2a standard, this latest version increases the maximum link bandwidth to 32.4 Gbps, with each of four lanes running at a link rate of 8.1 Gbps/lane a 50% increase from the previous version of the DisplayPort standard. Allowing for transport overhead, DisplayPort's 32.4 Gbps combined link rate delivers 25.92 Gbps of uncompressed video data.
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 DisplayPort's 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.
DisplayPort 1.3 continues to support video conversion to VGA, DVI and HDMI. DisplayPort 1.3 adds support for HDCP 2.2 and HDMI 2.0 with CEC (Consumer Electronics Control), which enhances DisplayPort's 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.
DisplayPort 1.3 also enhances DisplayPort's value for multi-function interfaces that combine data transport, A/V transport and other capabilities on a single cable. 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.
While becoming a mainstream video standard, DisplayPort continues to be at the cutting edge of A/V transport, said VESA Board of Directors Chair Alan Kobayashi, Fellow & Executive R&D Management for DisplayPort Group at MegaChips Technology America. These new enhancements to DisplayPort will facilitate both higher resolution displays, as well as easier integration of DisplayPort into multi-protocol data transports, which will satisfy consumer's desire for simplicity and ease-of-use.
The DisplayPort standard is offered to VESA members without any license fee. For more information about DisplayPort, please visit http://www.displayport.org or connect with us on YouTube.

•One 4K monitor @ 60 fps with simultaneous support for full-speed USB 3.0, Too bad they could not support USB 3.1, or the ability to push more USB/other protocol data over the video channels, for times when 4k was not needed. Maybe someone can write drivers that can encapsulate more general data over display port’s video protocol, and create faster data transfer for backups, other uses when not gaming, or doing graphics workloads.
USB 3.0, over DP 1.3, is a start, and let’s hope that mobile/laptop devices will have more than one USB 3.0 controller connected to a sufficient number of PCI lanes, so the devices can push out more than 5 Gbs of USB data, backup/file transfer data speeds can never be fast enough, the more bandwidth the faster the backups/transfers.

A lane is up to 8.1 Gbps, so not quite the 10Gbps of USB 3.1 but certainly closer that is was. I suppose you could hope for specialized products that team lanes for USB as opposed to graphics.
It really shouldn’t be called
It really shouldn’t be called 5K. While there is a “5” in 5120 x 2880 the acutal pixel count is 7.1 times as large as FullHD (“1K”). 4K has exactly four times as much pixel as FullHD.
4k and 5k are actually
4k and 5k are actually cinematic standards, they specifically refer to the 5120×2880 and 4096×2160 resolutions. Marketing companies have been touting the phrase 4k when they really mean UHD (Ultra HD which is also 4 times the size of FullHD). The cinematic naming convention literally just means how many pixels, as in close to 5k or 5 thousand, which the 5120 is.
