Milpitas, Calif., and Las Vegas, Jan. 07, 2010 – The Video Electronics Standards Association (VESA) today formally unveiled the industry’s most innovative and flexible digital communication interface standard for transporting display, audio and other data.

VESA’s DisplayPort Version 1.2 is a comprehensive extension to the original DisplayPort standard offering many new benefits to the end user. Benefits include: double the data rate of the previous DisplayPort v1.1a standard (enabling higher performance 3D stereo displays, higher resolutions and color depths, and fastest refresh rates); multiple monitor support from a desktop or notebook computer using only one DisplayPort connector; the ability to transport USB data between a PC and Display, supporting Display USB functions such as a webcam and USB hub.

DisplayPort v1.2 is backward compatible with existing DisplayPort v1.1a systems, including existing cables and the Mini DisplayPort connector. DisplayPort v1.2 increases performance by doubling the maximum data transfer rate from 10.8 Gbps (Giga-bits-per-second) to 21.6 Gbps, greatly increasing display resolution, color depths, refresh rates, and multiple display capabilities.

DisplayPort v1.2 supports “multi-streaming”—the ability to transport multiple independent uncompressed display and audio streams over a single cable, supporting protected content and high performance applications such as 3D gaming. This enables the use of multiple monitors connected by cable in a daisy chain or hub configuration.

Whereas the current Display v1.1a standard can support one 2560 x 1600 monitor at 60Hz, DisplayPort v1.2 can support two such monitors with one cable, or four 1920 x 1200 monitors. Many other combinations are possible, including multiple video sources, multiple displays (even at different resolutions) and multiple audio speakers.

Another new feature is the ability to support high-speed, bi-directional data transfer, allowing USB 2.0 or Ethernet data to be carried within a standard DisplayPort cable. For DisplayPort v1.2, the maximum data rate of this “AUX” channel has been increased from 1 Mbps (Mega-bit-per-second) to 720 Mbps, providing suitable bandwidth for USB 2.0. The DisplayPort cable can therefore support USB data to/from the display to support Display USB functions, in addition to sending the video and audio information. Standard
Ethernet can also be transported in the DisplayPort cable.

DisplayPort v1.2 was designed to be compatible with existing DisplayPort systems and cables. To take advantage of the new capabilities, a PC will need to be DisplayPort v1.2 enabled, however existing standard cables can still be used, including those with the new Mini-DisplayPort connector. To achieve the 21.6 Gbps rate, the per-lane data rate is doubled from 2.7 Gbps to 5.4 Gbps, over the four lanes that exist in the standard cable.

For a single display, this enables up to 3840 x 2400 resolution at 60Hz, or a 3D display (120Hz) at 2560 x 1600. DisplayPort v1.2 also adds new audio enhancements including the following:
-- Audio Copy Protection and category codes
-- High definition audio formats such as Dolby MAT, DTS HD, all Blu-Ray formats, and the DRA standard from China
-- Synchronization assist between audio and video, multiple audio channels, and multiple audio sink devices using Global Time Code (GTC)

DisplayPort v1.2 also includes improved support for Full HD 3D Stereoscopic displays:
-- Life-like motion using up to 240 frames-per-second in full HD, providing 120
frames-per-second for each eye
-- 3D Stereo transmission format support (Field sequential, side by side, pixel interleaved, dual interface, and stacked)
-- 3D Stereo display capability declaration (Mono, Stereo, 3D Glasses)

“DisplayPort is a truly open, flexible, extensible multimedia interconnect standard that is ubiquitous in the PC, notebook and display markets and is rapidly gaining traction in consumer electronics applications,” said Bill Lempesis, VESA’s executive director.
“DisplayPort Version v1.2 offers a complete set of benefits and capabilities that no other standard can provide. It is completely backward compatible with DisplayPort v1.1a and requires no new cables or other equipment, making it the standard of choice across the industry.”

2560x1600 120Hz capability? Where do I sign up for such a display? :D

[Blacky]

Wow nice :eek:

[RPGWiZaRD]

Nice indeed, just hope there won't be much input lag. I hope this will make displayport even more popular and hopefully a standard on gfx cards soon so they have at least one DP port on all gfx cards.

[BrowncoatGR]

More DRM.... :down:

[RaZz!]

tbh, that's what displayport should have been from the beginning... so i think all people who bought new graphics cards with displayport 1.1a will be pretty pissed now...

No kidding.

[Mech0z]

Very nice, but HD5xxx only have the old standard right? If so then its too bad :/ then this wont hit until end of 10' when hd6xxx comes out.

We need displays supporting this standard also, so there is still time. But I believe it will get very popular in the future.

[slim142]

Some displays are coming out with DP, now with the new DP 1.2, I hope to see manufacturers including it even on their cheap 19" monitors. That would push DP to become popular and a default standard.

Im liking DP even more every day.

[Tech Dav]

it was really slow moving but I can see it doubling bandwidth again in a few years when 4k, 3d and 120hz become standard

DisplayPort is designed to be connected directly to the panel itself. One of it's main goals is to replace the display connection used internally on laptops and then you have to connect it directly. With DVI and HDMI there is a 'translation' chip between the connection and the display. I theory DisplayPort should thus be able to decrease input lag and it's actually cheaper. It depends on how the manufacturers will implement it though, they may still choose to put a 'translation' chip between the connection and the display.

[Manicdan]

i think we need another 5 years before we all start saying how the hell did we put up with dvi

[Sly Fox]

So does this still have the lag caused via DRM that the old one had? That's a deal breaker for me.

[grimREEFER]

so, now that diplayport can handle the hd audio codecs and 3d, are they gonna become a standard port on recievers and tv's?

[Tenknics]

I have a DP monitor, trusty old 2408wfp. Connected via DP to my laptop, its a great setup. Ive been using DP for awhile now on this monitor and dvi prior to that. DP is much nicer imho. Its hard finding 1920x2280 wallpapers so I made one..

Probably :mad:

[[XC] Oj101]

standard on the g300 cards maybe? :D i mean they're still a few years away anyways!

This is REALLY getting old now :rolleyes:

Why don't we use DP instead of HDMI?

Please can you send that to me? :yepp:

Could you tell me where that story is coming from? You're the first I've seen mentioning it. DisplayPort should allow for lower input lag than DVI and HDMI.

[Behemot]

Noooo. Why? Another good looking standard meesed up. Idea of DP is broken every day due to manufacturers want to VGA support DVI and HDMI through DP, DP and DVI through HDMI or every other setup you can imagine, so there IS some aded controller every time, you can forgot on some better lags. I love nice old DVI - there is one version, no unneeded stuff.

Why Ethernet my god? We don't have 8pin cables for that? USB? For what?? Is this really necessary? Even I'll probably get lost in all of this bull:banana::banana::banana::banana:, not mentioning average consumer. Usually things like set-top boxes (or whatever you call it) from you ISP (like Telefónica) support nothing, you are glad if you even make the audio and video work. Many people end with having video via HDMI and sound via standard jack or something else. It's due to so many standards, versions of those and terrible final implementation.

I would like all this new stuff if, only if, the DP can handle audio, video and data at once, kill every other port and it would be somehow convertable to at least some of older ports. Than every single audio/video machine can have 6 DP and you're done. But as long as there is so many connection possibilities (and usually those you need at the moment are not there, I personally love these situations), it's just making situation worse.

Agreed... Honestly, what's wrong with DVI? We used VGA for like 20 years and now all of a sudden we need a new standard every 6 months. What the hell is going on people?

[STaRGaZeR]

DVI doesn't have enough bandwidth for 120Hz and high resolutions.

[RPGWiZaRD]

Well I like the idea of 120Hz at higher res or even 240Hz if I'd use 3D vision so I could still enjoy 120 FPS per eye and DVI cannot provide this.

They call that evolution. It will bring simplicity (DVI is a bulky connector compared to the much simple DP) and high bandwidth. What they want to do is have a small and powerful connector that can do it all without much hassle. What's the matter :up:

I don't think DisplayPort will ever replace HDMI, they will probably coexist. DP was mainly aimed to replace replace DVI and the LVDS based link used in notebooks (LDI, FPD-Link, OpenLDI etc.). HDMI will probably stay where it currently is, firmly in the TV market. DP will probably become more prevalent in the PC and notebook market.

The extra data port for USB is quite useful actually, makes connecting a touch screen much easier, especially in notebooks for example. Can also have it's use in desktop monitors of course, for build in webcams, card reader and even touch screens. Why you'd want to run an Ethernet connection going through your DP is beyond me though.

lota good points

DP was to replace DVI, i hope it replaces HDMI too. for the ethernet, i can see that being for tvs to work as a PC, the chips in a nice TV have alot of power and should be enough to let it get automatic updates and on screen UI changes.

[zalbard]

Talking about Ethernet, perhaps it might have something to do with video-on-demand stuff some ISPs are starting to offer?

[Behemot]

Idea is nice, the matter is both will stay anyway. If not directly DVI, than at least DP-to-DVI, through some I/O, throwing lag potential away. Most people will still have 60Hz monitors up to some 1080p in next years, so the DVI will stay long time (realize the cheapest panels still have D-Sub only!!). All those 3D things are not standardized (e.g. AMD vs. NVIDIA) and pretty pricey.

All in all, another standard to current mixture, not replacing anything at least in near future, just complicating things even more.

What I don't like is they are not predictable. They cannot made DP so fast in first version with enough room for 3D or anything else needing so high bandwith?
