Displayport v1.2 lands
THE VIDEO ELECTRONICS STANDARDS ASSOCIATION (VESA) has given its blessing to Displayport v1.2, which introduces a plethora of new features to the communication interface.
As well as doubling the data rate of the existing v1.1a standard to 21.6 Gbps, the update allows for multiple monitors to be connected to a single Displayport connector and adds support for transporting USB data at up to 720Mbps, enabling embedded webcams, speakers and USB hubs over a single cable. Ethernet data is also supported
To achieve the 21.6 Gbps rate, the per-lane data rate across each of the four lanes has doubled from 2.7Gbps to 5.4Gbps. For a single display, this enables a single display with a resolution of up to 3840x2400 at 60Hz, or four monitors at 1920 x 1200, or alternatively a 3D display at 120Hz and 2560x1600, as this will effectively use two streams simultaneously.
The improved data rate will allow for richer, larger and higher resolution displays and the new version is also backward compatible with the current display technology, so all the ports, cables and devices will be interchangeable, although they will revert to the lowest common denominator.
"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," said Bill Lempesis, executive director of VESA.
With HDMI becoming increasingly common, Displayport has been slow to become a widely used connection interface, however Lempesis reckons that it is "a truly open, flexible, extensible multimedia interconnect standard" and "is rapidly gaining traction in consumer electronics applications."
Displayport v1.2 also adds new audio enhancements including multiple channels, video synchronisation assistance and support for high definition audio formats such as Dolby MAT, DTS HD, Blu-Ray and the DRA standard from China, as well as the RIAA friendly Digital Restrictions Management (DRM) copy protection and category codes.
For those wanting to jump on the 3D band wagon there is improved support for Full HD 3D Stereoscopic displays, which provides a full HD image at 120 frames-per-second for each eye, in whichever 3D format you like including field sequential, side by side, pixel interleaved, dual interface, and stacked.
Although no time scales have been given, now that the updated standard has been given the go ahead it shouldn't be too long until devices making use of these new features start tipping up. µ

HDMI is not really bad as I saw stated in a few comments here but displayport really looks like a good contender. You can see here an interview where Displayport is being compared to its previous standards, HDMI and DVI: http://www.thehdstandard.com/hardwaresoftware-solutions-for-streaming/displayport-1-2/

@jason: All Displayport connectors lock = _so_ much better than HDMI garbage. Good topic to bring up!
This is about a transmission standard, not your shitty LCDs and software problems. No number of Display-ports can do anything about that.
that LCDs aren't all that: OLEDs. World plus dog is clamoring for something that has decent color, OLEDs are saying they can do it. We will see.
BTW, here is a prediction: When the OLEDs come out they will boot up with a headache inducing refresh rate.
let me know when those morons get 1920x1200 @ least 100hz without the fucking LCD lag.. both input and output delays. I alredy have a useless 24" lcd that does 1920x1200 @60hz and quite frankly its utter shit, slow laggy response, absolute crap for fps gaming.. absolute crap for most gaming actually because you're stuck with only having 1 native resolution, so you either play games at crap low low quality at native res and stick get shitty FPS, or you go for a lower resolution and then screen makes things like utter fucking blocky rubbish, or you play shitty windowed mode with desktop crap surrounding your game window.
FUCKING LCD MANUFACTURES NEED A GOOD KICKING. older CRT monitors still haven't been out done by this average consumer lcd display garbage that is marketing to noobies.
@bill you're a fucking moron, I still use my 21" flatscreen crt for gaming at 100Hz and any resolution I choose for best FPS/quality because no LCD on the market has been able to beat it for performance or color. Laggy LCD's are for fucking noobs who are slow and usless and don't notice the poor responsive times and the delayed screen output. And quite frankly those things matter more to me than deskspace.
I want Displayport v2.0.. for dual screen 24" 1920x1200@120hz ...not some shitty half assed widescreen with bare minimum 1080p crap height. That shit is for noobs.
Two TFTs - correctly detected at 60Hz.
One CRT via DVI-A - correctly set up at 1600x1200x85Hz.
Another CRT via a KVM - that doesn't detect properly but can be manually tweaked.
Win 7, Nvidia 8800GTX and 7600GT. No problem. Same with Vista.
posted by : jason, 19 January 2010 - Jason made a very good point about these filmsy connectors. Just look at IDE vs SATA. You could properbly "hang" a whole computer with IDE cable connection, but SATA would not even hold your CPU fan!
And even though Hdmi looks good on paper, the connector is just as poor as SATA. We want something solid like IDE and DVI connection for next genrations.
As for ATI even with 5870 hardware, they still cannot get rid of the resource hogging Catalyst Centre. Why can't they implement something like Nvidia control Panel? Nice, slim, tidy and best of all, it works without the hassels!
Well!
I am currently using a pc by Fujitsu (Japan) called the FMV Deskpower and these computers have a proprietary display connector called Display+ (30-pin sleek connector) that carries digital video, sound, usb, RF (wireless KB/mouse), Infrared (remote control) and other data in a single cable!
And this tech was made available from 2003 ... I think they have moved on ... but its good to see something like this coming back ... though we have All-in-One PCs becoming popular ... Take a look at www.fmworld.net (japanese only)
I remember trying CCC (ATi's Catalyst Control Center), but it did not let me override the refresh rate. It did not recognize my monitor other than as a generic Plug 'n Play fixed at 60hz. I am glad to see ATi has the RefreshRate Fixer. That looks like something I could have used at the time.
As it was, I ended up doing an EDID trick to fool Win7 into thinking it was some other type of monitor.
I just tried going back to a generic Plug 'n Play monitor to see if CCC could override it and to try out the RefreshRate Fixer. Not surprisingly nothing worked; I could not get Win7 back to a generic PnP. Bravo Microsoft!
I blame Microsoft for most of this problem. But NEC, Intel, AMD, ATi, (I know they are now DAAMiT) and all the other VESA members are also to blame for this refresh rate rigamarole. They never did figure it out, and this is 2010, some 25 years of working on it.
And now they are talking 3d? Gigabit this and HDMI that and DVI here and Displayport there and multi-screen and blah, blah, blah. Good luck with it all!
I reiterate: the same VESA clowns who can't deliver 1024x768 @ 75hz on a simple single 15" CRT monitor are certain to muck up the stuff mentioned in this piece.
I didn't read the prev.comments properly. whoops!
...is it only on CRT monitors you see the flicker at low refresh settings.
I myself was very sensitive to flicker even *at* 75Hz on my last CRT monitor ... but I have absolutely no problems at all viewing my 60Hz LCD panels all day.
I thought it was the fade of the phosphor elements on CRT's between refresh cycles that was picked up by the eye, whereas on LCD's the pixel stays lit until signalled to change.
I have not had much first hand experience with Displayport but I have had plenty with HDMI. I know Displayport has a tiny connector just like HDMI and I wonder if it makes contact just as poorly as HDMI and has a tendency to break. DVI is a much better type of connector physically speaking, I would like to see a version of Displayport that uses a connector similar to DVI.
"Full HD 3D Stereoscopic displays, which provides a full HD image at 120 frames-per-second for each eye"
I believe you meant 60 fps per eye, 120 fps for both eyes.
To our CRT loving friend, I changed to LCD ages ago and never looked back. Color reprodution, geometry aligment and digital interface are highs in LCD monitors. Bad things are contrast and bright. But I find both acceptable on my monitor, could be better though.
Unles you are a frag addicted, I see no reason to use CRT nowadays.
(Nope, the spec is for 240 frames per second, 120 for each eye - Ed)
Just install CCC, or ATI Radeon RefreshRate Fixer.
ATi cards can't output anything other than 60Hz without Catalyst Control Center, or a 3rd party application that is able to change the refresh rate. No matter what refresh rate setting you put in the Windows properties box, if you don't have CCC, it will always run at 60Hz.
get 1024x768 working at 75hz first before they start working on all the new fangled features.
Win7, ATi 5770, NEC MultiSync 4FGe comes up at 1024x768 at a headache inducing 60hz. Bravo Microsoft! Bravo ATi! Bravo VESA!.
Same for Fedora 12 and Ubuntu 9.04 using the latest VESA X.org driver. Bravo boys!
Get my 15 inch 4FGe working properly first, then worry about 3d, multi displays and the gigabits per second.
BTW, these LCDs are inane. The old CRTs have much better color.
Don't hold your breath waiting for these VESA clowns to get 3d working either. It will never work.
