VESA Introduces Updated Dual-Mode Standard for Higher Resolution Interoperability with HDMI Displays

The Video Electronics Standards Association (VESA®) today announced the latest release of the DisplayPort Dual-Mode Standard. This release supports the next generation of Dual-Mode DisplayPort enabled personal computers and Dual-Mode DisplayPort cable adaptors, expected to be available to consumers later this year. Among several refinements to improve interoperability, the updated standard enables a higher data rate for DisplayPort-to-HDMI cable adaptors, providing support for HDMI 1.4 display resolutions such as 1080p 3D at 60Hz, and Ultra HD (4K x 2K) up to 30Hz frame rate, as well as 1080p with deep color.

“The first Ultra HD displays were introduced in 2012, but today’s Dual-Mode DisplayPort-to-HDMI cable adaptors limit display resolution to 1080p,” said Craig Wiley, senior director of marketing at Parade Technologies, and VESA Board of Directors chairman. “For a personal computer to fully support HDMI 1.4 or deep color, today a separate HDMI output is needed. This updated DisplayPort Dual-Mode Standard version 1.1 enables full support of HDMI 1.4 video modes, and 1080p deep color, using a simple cable adaptor plugged into the system’s DisplayPort output. This helps to reduce the number of interface ports needed on a Personal Computer, which is desirable as form factors shrink.”

Developed by VESA’s nearly 200 leading industry member companies, the DisplayPort Dual Mode Standard defines the requirements for Dual-Mode DisplayPort source devices and Dual-Mode DisplayPort cable adaptors. DisplayPort was developed to provide a single video interface that both provides advanced features as well as interoperability with legacy displays including VGA and DVI, and HDMI. The new Dual-Mode Standard is in line with this objective by enabling the support of the latest HDMI standard, HDMI 1.4. In addition to releasing the DisplayPort Dual-Mode Standard Version 1.1, VESA is also releasing an updated DisplayPort Dual-Mode Cable Adaptor Compliance Test Specification, version 1.1. Conformance to the updated Compliance Test Specification, or CTS, is required for using the DisplayPort logo with a Dual-Mode Cable Adaptor.

A Dual-Mode DisplayPort source is a device, such as personal computer, that can logically output either DisplayPort or TMDS (Transitional-Minimized Differential Signaling) from the DisplayPort output connector, enabling the support of DisplayPort, DVI, and HDMI monitors. An additional device, specifically a Dual-Mode DisplayPort cable adaptor, is required to convert the mechanical connector, as well as the electrical aspects of the signal, to output that is compatible with a DVI or HDMI cable and display. A Dual-Mode DisplayPort source automatically detects the presence of a plugged-in Dual-Mode DisplayPort cable adaptor and provides the DVI or HDMI signal, as required, to support the connected DVI or HDMI monitor.

Prior to the updated Dual-Mode Standard release, Dual-Mode cable adaptors were limited to a TMDS clock rate of 165MHz providing support for display resolutions up to 1080p with 60Hz and 24 bits color. In this latest specification, a new Dual-Mode cable adaptor configuration is defined that enables a TMDS clock rate of up to 300MHz. While the DVI standard limits TMDS clock rates up to 165MHz, the HDMI 1.4 specification allows TMDS clock rates up to 297MHz, enabling the support of 1080p 3D at 60Hz, or Ultra HD (4K x 2K) up to 30Hz frame rate.

With the release of this new VESA specification, existing adaptors will now be referred to as “Type 1” adaptors, and the new adaptors as “Type 2.” A Type 2 adaptor will be backward compatible with an existing Dual-Mode DisplayPort source device, but it will only support up to a 165MHz TMDS clock rate unless it is used with a “Type 2 enabled” Dual-Mode DisplayPort source device. Some existing systems will be software updatable to support Type 2 adaptors. A Type-2 enabled Dual-Mode DisplayPort Source devices, together with a Type 2 Dual-Mode DisplayPort-to-HDMI adaptor, will enable support for HDMI 1.4 display modes such 1080p 3D at 60Hz, or Ultra HD (4K x 2K) up to 30Hz frame rate, as well as 1080p with deep color. Type 2 adaptor prototypes are currently available from multiple suppliers.
