When will the first DisplayPort-equipped products come to the market?

Several major companies are now shipping products that include DisplayPort technology with more on the way. Some examples of displayport technology already in the marketplace is Apple who have standardized the displayport connector on all their MAC Cinema Display Monitors.

Which types of products do you expect will be the first to incorporate DisplayPort?

It is anticipated that PC manufacturers will adopt DisplayPort as a solution for connecting all types of displays–including monitors, projectors and HDTVs–with a single connector. DisplayPort will also be adopted in LCD panels.

Are customers actively asking for this kind of interface now?

Customers have been asking for smaller connectors, easier set up, thinner cables, fewer cables, higher color depths, higher refresh rates, higher resolutions, digital projectors, thinner and sleeker displays, and ubiquitous display connectivity–all the features which are currently being supported by Displayport.

What are the most significant benefits for the user: fewer connections and plugs with each product, for example, or fewer cables?

The main product benefits are that DisplayPort provides improved performance as a standard feature relative to DVI, and can be packaged into a USB-sized connector for space-constrained applications like notebooks and graphics cards. DisplayPort also enables ultra sleek, easy to use direct drive flat panel monitors and sets the stage for future display features such as single-cable multi-function monitor connectivity and daisy chained displays. DisplayPort enables a wide range of connectivity options to monitors, projectors and HDTVs via a single connector, making it an easy, universal and cross-application solution.

Wasn’t DisplayPort conceived as a computer interface originally, or has it been contemplated for CE systems since its inception?

DisplayPort was originally intended to provide a common replacement for LVDS, DVI and VGA, but while DisplayPort has a rich A/V feature set, it is expected to complement, not replace, HDMI.

How will VESA handle the issues of interoperability to be certain that DisplayPort- equipped products are able to work together?

VESA has developed a DisplayPort Compliance and Interoperability program to assure that products carrying the DisplayPort certified logo interoperable successfully.

Is there going to be a logo program indicating that a company’s product complies with the DisplayPort standard?

Yes. VESA is administering a DisplayPort logo program via the DisplayPort website. Products that successfully pass the compliance and interoperability tests are eligible to receive and use the DisplayPort certified logo.

Will DisplayPort work with standards like HDMI and VGA, or replace them?

DisplayPort is designed to replace LVDS, DVI and eventually VGA. While DisplayPort has a rich A/V feature set, it is expected to complement, not replace, HDMI, and the connector is compatible with HDMI signals. A multi-mode device that implements both HDMI and DisplayPort only needs a simple cable adapter to make an HDMI connection.

How will DisplayPort be implemented with existing or legacy TVs and other products? Is there going to be an adapter or similar system available soon?

Guidelines for DisplayPort-to-DVI and DisplayPort-to-HDMI adapters are provided in the VESA DisplayPort Interoperability Guideline. Other types of adapters, such as DisplayPort-to-VGA, are also anticipated.

Will content protection be implemented in the specification, and how?

The DisplayPort 1.1a specification includes protocol hooks for HDCP v1.3 DisplayPort supports content protection but does not require it, though it is widely anticipated that all consumer applications of DisplayPort will include content protection. Content protection systems will continue to have license agreements and specifications that are separate from the DisplayPort specification.

Why not simply use HDMI as a VGA replacement for PC monitors?

HDMI was designed as an HDTV interface, not a general-purpose internal and external display interface for IT equipment. Many of DisplayPort’s unique benefits, such as direct drive monitor design and single cable multi-function monitor connectivity are not available with HDMI. High resolution support and high performance are standard features of DisplayPort, whereas these are optional premium features of HDMI. Business and enterprise customers may not want to implement all of the consumer electronics features that are required in HDMI products DisplayPort is designed to meet the future needs of the PC industry while preserving compatibility with HDMI.

What is Displayport?

Posted on July 13, 2009, 6:53 pm, by admin and received No Comments ».

DisplayPort is the next generation digital display interface standard design to replace DVI, LVDS, and eventually VGA. DisplayPort delivers higher performance, enables exciting new monitor designs, improves digital display connectivity, and provides a roadmap for future display usages.

It was developed by members of the industry who saw the need for improved display experiences that could be implemented ubiquitously across complete product lines.

Supported by the 180+ member companies of VESA (Video Electronics Standards Association), representing a significant cross-section of the computer and consumer electronics industry, DisplayPort represents the next generation of digital display interface standards.

Background on VESA ( Video Electronics Standards Association).

VESA is an international non-profit corporation led by a Board of Directors, which represents a voting membership of more than 165 corporate members worldwide. VESA supports and sets industry-wide interface standards for the PC, workstation, and consumer electronics industries. VESA provides a forum to develop, promote and support open standards for the display industry.

The DVI interface will is headed for retirement, as HDMI and Displayport are establishing themselves as successors for the interface. Market researchers from In-Stat believe that DVI shipments will “begin a steep decline” in 2008: The technology has been included in more than 112 million devices in 2007, but will only be included in an estimated 3 million devices in 2011, according to In-Stat. Brian O’Rourke, an analyst with In-Stat, said that 143 million HDMI devices shipped in 2007; 90% of all Digital TV’s shipped during the year included HDMI. However, Displayport emerges as the primary competition of DVI and DVI shipments will decline through 2011 as a result, In-Stat said.

Even though both DisplayPort and High Definition Multimedia Interface (HDMI) were developed with different priorities in mind, their co-existence on the market inevitably means competition between the two standards for display and audio interconnection. Market research firm iSuppli believes that DisplayPort will mostly be used on the market of personal computers, whereas HDMI will remain de facto standard in consumer electronics (CE).

iSuppli forecasts that global shipments of DisplayPort-enabled equipment will grow to 263.3 million units by 2012, up from zero in 2007. Meanwhile, HDMI-enabled equipment will grow to 772.8 million units in 2012, rising at a Compound Annual Growth Rate (CAGR) of 32% from 193 million units in 2007. While HDMI has been adopted by desktop and mobile PC platforms and presently surpasses DisplayPort in this market, iSuppli expects that DisplayPort will take over the lead in this market after 2010, as PC OEMs move away from VGA interfaces and adopt HD solutions.

“iSuppli believes that the DisplayPort interface standard will be the successor to the venerable VGA interface on PC monitors as well as desktop and notebook PCs. However, both DisplayPort and HDMI will see healthy unit growth in the PC equipment space as more consumers jump on board the convergence bandwagon at home,” said Randy Lawson, senior analyst for digital TV and display electronics at iSuppli.

DisplayPort has perhaps its most significant opportunity in the embedded or internal-only video interface applications market, such as Liquid Crystal Display-Televisions (LCD-TVs) and mobile PCs, where a high bandwidth serial interface solution designed specifically for such embedded display interfaces could find a home. This is a potentially huge opportunity for the technology, as iSuppli predicts more than 600 million mobile PCs and 550 million LCD-TVs will be shipped during the period of 2008 to 2011.

While DisplayPort will see some long-term success as a replacement for DVI and VGA interfaces in the PC market, as well as a potentially embedded interface replacement, HDMI penetration is already very high. With the release of HDMI 1.3, iSuppli believes this as well as future updates and revisions will maintain HDMI’s dominance in the consumer-electronics space.
