VESA DisplayPort 1.3 standard Outlined
VESA informed the press of a publication on the upcoming DisplayPort 1.3 standard. This new spec doubles signal bandwith towards up to 32.4Gbps. The higher bandwidth is needed for 5K screens with a resolution of up to 5120 x 2880 pixels as well as using not one but two 4K UHD displays.
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.

Yes, and not only that. It has enough bandwidth to pump 480Hz @ 1080p.
And 270Hz @ 1440p.
It is just question of time before some manufacturer goes to real 240Hz.
So if it can do 4k over two lanes at 60hz, does that mean were finally talking 4/5k resolution at 120hz being possible assuming we utilise all 4 lanes?

Some strong stuff they have there. Pass me some maybe?

Question here,
Does display port 1.3 will need new display port connectors ?
I ask this because I'm wondering if Geforce 900 series displayport connectors will support 1.3 standard ?
This might be a reason for me to wait for a card that does support DP1.3

connector will very likely be same, because it already has 4 lanes for data streaming.
But it is more question of frequencies at which graphics card can transmit data without error.
But if GTX970/980 is not released as DP1.3 compliant then it will not upgrade just by vBIOS update.

Well... I'd like if my DisplayPort 1.1 laptop was updated to 1.2
No, it's not that easy. We'll see if GeForce 9xx and Radeon 3xx will be able to support such bandwidth, and more important - if it makes any sense, as we're talking about lots of pixels, and today it's difficult to play at high frame rate even at 2560x1440, not to mention 4k or 5k. Even SLI/CF systems would struggle. Adaptive VSync will make things easier, but nonetheless it's not an easy task (with 5k@60fps we're talking about 885 millions pixels per second).

Being a mid-range gamer my next monitor will probably just be a 1080p 60Hz panel (currently still rockin my old 1680x1050). But I would love if I could get one that supported DP 1.2a or 1.3 without paying a huge premium.

We just have to wait a bit. I think it's a really bad time for an upgrade right now unless one has a lot of money to spend. I'd upgrade when adaptive vsync gets better (if any) adoption rate, so you'd be able to get way better smoothness-to-cost ratio. And at that time, USB 3.1 should be available too.

4k @ 120hz (or more). Hazzah!
