Displayport has been around for some time now, but was much more apparent at this year’s Consumer Electronics Show. In fact, The Video Electronics Standards Association (VESA®) announced at the show, the rapid growth of certified DisplayPort™ products during 2012.

VESA demonstrated various DisplayPort functionalities such as Multi-Stream (MST), daisy-chained monitors, Mobility DisplayPort (MyDP), Embedded DisplayPort (eDP) and High Bit Rate (HBR2). VESA also showcased its exclusive feature of delivering Ultra HD resolution at 60 frames per second, a feature no other display standard is capable of doing today.

Quote:
Over the last twelve months, the number of certified DisplayPort products increased by 80 percent, further establishing the DisplayPort ecosystem as planned by the personal computer industry to increase display and system performance.
Quote:
During 2012, DisplayPort certifications have increased across all device categories and have expanded into new categories. Certification in computer monitors has grown 95 percent, projectors 100 percent, and graphics cards 18 percent, and there was a 20 percent increase in cable products.
Quote:
The increasing adoption rate signals a vote of confidence in DisplayPort and the growing DisplayPort ecosystem. As consumers become accustomed to the various benefits and superior visual experiences, this will increase DisplayPort demand. We will see further grown of certified DisplayPort products and continued expansion into other categories, including in TVs, in the coming year.


For those of you who don't know all the details of DisplayPort

Quote:
VESA’s DisplayPort standard is a high-bandwidth video interface designed to enable features not available with other electronic connections, delivering true digital imaging and audio through a single cable. DisplayPort is the only video interface that supports multiple displays and Ultra HD at 60 frames per second from a single video output. DisplayPort significantly enhances display performance by doubling the maximum data transfer rate enabling multiple displays and increasing display resolution, color depths, and refresh rates when compared to other display interfaces.

Even though we don't quite know the bandwidth that will be needed to transport 4K content due to the lack of codec present, DisplayPort has been able to demonstrate it's efficient and powerful means of transportation.

DisplayPort is very strong in the IT world, do you think it might ever dominate over HDMI?

HDMI 1.4 is supposed to have the bandwidth required for UHD. When they marry HDCP with displayport, it will take a another year or two to iron out the bugs. So, I doubt it will dominate. It may also be offered as an alternative.

HDMI 1.4 has enough bandwidth for UHD at 24 or 30 fps, but not 60. The HDMI Forum is working on the next-gen spec that will double the current bandwidth and include various other enhancements; I'm told by Steve Venuti, president of HDMI Licensing, that the new spec is in the final stages of development and should be released some time in the first half of this year. Plus, HDMI is so entrenched in the consumer-electronics world, it will be difficult for DisplayPort to supplant it, IMO.

Good observation. HDCP is already compatible with DisplayPort version 1.1 and they already sport their own called DPCP (DisplayPort Content Protection.

As far as HDMI goes though, although many HDMI cables state they are HDMI 1.4, they are not and fail bandwidth tests. I think when we start seeing more and more 4K content arrive in the homes, we will start seeing HDMI cables that stated were 1.4, but we're never approved or tested properly.

Check out www.dpllabs.com for more info.

I don't think it will take over, but what is quite apparent to me is that many IT manufacturers are jumping in to get products using DP. CES was a perfect example of that.
