VESA® Announces Updated Embedded DisplayPort™ (eDP) Specification Version 1.1a; Defines Requirements for the Video Interface to the LCD Panel in Notebook
PCs and other Embedded Applications
Milpitas, CA., November 17, 2009 – The Video Electronics Standards Association (VESA) issued its updated Embedded
DisplayPort (eDP) specification, a companion standard to DisplayPort Version 1.1a. The new eDP™ version provides an updated definition of requirements and
options for the standard panel interface in embedded display applications.
The eDP specification defines a particular set of DisplayPort features to be used in embedded applications including
notebook PCs and all-in-one PCs. eDP version 1.1a includes further definition on display authentication for protected video content, addresses Sink device AUX
channel interrupt requests, and makes enhancements to the 4-lane connector used for 3D display applications.
eDP is based on the VESA DisplayPort 1.1a standard. The DisplayPort standard is oriented toward external applications
with emphasis on interoperability between system vendors and interconnection cables. Newer PC chipsets and GPUs designed for notebook PCs support both DisplayPort
and eDP from the same video port connections, enabling configuration options to the system integrator.
"Ongoing enhancements of the eDP specification will continue," says Craig Wiley of Parade Technologies, VESA Board Member
and Notebook Task Group Chair. "As system integrators realize the flexibility, display control capability, and power savings of the eDP interface, they want to see
these enhancements standardized in the panel industry. Notebook PCs with eDP panels will hit mass production in Q1 2010, and is expected to overtake the volume of
notebooks with traditional LVDS panels by 2012."

VESA® Launches DisplayPort™ Cable
Adaptor Verification Program
Milpitas, CA., November 12, 2009 – The Video Electronics Standards Association (VESA) announced today its plans to
launch a DisplayPort cable adaptor verification program. DisplayPort cable adaptors allow a DisplayPort interface to connect with other video interface types
such as DVI, HDMI™ or VGA providing consumer devices compatibility as the PC industry transitions to DisplayPort. The launching of this new verification
program enables the consumer to easily identify cable adaptor products that have been tested for interoperability between various source and display types.
VESA will initially offer verification testing for Source-side DP-to-DVI and DP-to-HDMI cable adaptors, due to their
popularity and importance in the PC industry. OEMs seeking DP-to-DVI or DP-to-HDMI cable adaptor verification should contact VESA at
http://www.vesa.org/About/locations.htm.
Verification testing of the DP-to-DVI and DP-to-HDMI cable adaptor types will follow the “DisplayPort Interoperability
Guideline Adaptor Checklist” which is available for download at http://www.vesa.org/Standards/free.htm, under VESA DisplayPort Related Standards. It is recommended
that developers of cable adaptors review the checklist to assure display interoperability and to achieve VESA cable adaptor verification. The checklist verifies
that the cable adaptor is implemented per the current VESA DisplayPort Interoperability Guideline, also available on the VESA web site.
VESA will offer the cable adapter testing at a minimal fee and will offer verification logo licensing. Cable adaptors
that pass the verification test will be listed on the www.displayport.org web site, a site provided by VESA to inform consumers about DisplayPort and to assist
them in making educated purchasing decisions.
Verification testing for Source-side DP-to-DVI and DP-to-HDMI cable adaptors will become available in early 2010.
Trial testing will take place at the DisplayPort PlugTest during December 7-10, 2009, in Yokohama, Japan.
Testing for DP-to-VGA adaptors, Sink-side adaptors, and other adaptor configurations will become available at a later date.
VESA® Issues Mini DisplayPort™ Standard;
Small Connector Supports Full Range of Capabilities Defined in DisplayPort Version 1, Rev. 1a
Milpitas, CA., November 10, 2009 – The Video Electronics Standards Association (VESA) today issued its
Mini DisplayPort (mDP) Connector Standard, defining the new, small connector that supports the full range of power, signaling and protocol capabilities
defined in the DisplayPort Standard Version 1, Revision 1a.
Mini DisplayPort meets the need for a smaller form factor connector for devices such as thin portable computers and
add-in cards with multiple display interfaces. The mDP connector can be used as an alternative to the standard DisplayPort connector defined in Version 1,
Rev. 1a.
The mDP standard defines the mechanical dimensions of the mDP connector and the cable assemblies and adaptors
that are supported. Devices using the mDP connector will meet all the electrical and protocol specifications required by DisplayPort 1.1a, and cable
assemblies incorporating an mDP connector at either or both ends must meet the cable assembly electrical specifications required by the standard.
Originally developed by Apple for its new generation of portable PCs, Mini DisplayPort is much smaller than DVI
(Digital Video Interface) or VGA connectors and enables full function display output on ultrathin notebooks and netbooks. Earlier this year, Apple agreed to
license the mDP interface to VESA for inclusion in the DisplayPort
standard.
VESA is finalizing DisplayPort 1.2, which incorporates mDP and doubles available bandwidth to 21.6 Gb/second. The
increased bandwidth enables new capabilities such as multi-monitor support via a single output connector, higher resolutions, refresh rates and color depths,
along with high performance 3D displays.
The mDP standard can be downloaded free of charge from www.vesa.org or www.displayport.org

VESA® Releases Display Subsystem
Power Management
Standard
Milpitas, Calif., September
15, 2009 – The Video Electronics Standards Association (VESA) today
announced the release of the new Display Subsystem Power Management
Standard.
This standard is intended to define a standard method of measuring power consumed in a portable computer
by the LCD display module. This standard is not meant to replace system level power consumption
processes and techniques. The EBL (extended battery life) power measurement process is a component
characterization tool only.
The display subsystem is a large consumer of power in a portable computer. As new display technologies
develop, the display subsystem must consume less power and keep pace with the reduction in overall platform
power consumption. Use of the process defined within this standard will reduce variables in the power
consumption process to aid in side-by-side comparisons of LCD modules from one or more LCD suppliers.

VESA® Releases Latest Monitor Control Command Set Standard; Version 2 Revision 2 Enables Enhanced Performance in Direct Drive Monitor Displays
Milpitas, Calif., April 20, 2009 – The Video Electronic Standards Association (VESA) recently issued Version 2 revision 2
of its Monitor Control Command Set Standard (MCCS), the baseline specification that lists a universal set of display controls and commands to support
communications between hosts and displays.
The latest revision of the MCCS incorporates Virtual Control Panel (VCP) codes and the document format adopted in
MCCS V3.0. Full compatibility with MCCS V2.1 is maintained. Also included in the new version are compliance requirements for all MCCS VCP codes. The changes
are intended to enhance performance in Direct Drive Monitor (DDM) displays.
Version 2 rev. 2 describes a standardized list of commands and controls used in identifying and controlling displays
through an application running on a connected host. It assumes that a video interface connecting the display to a host can issue an unsolicited attention call
to alert the host that something has happened outside its control. The targeted display devices are displays attached to the video output of PCs, industrial
display controllers or consumer electronic sources. The command and control list supports control of virtually all parameters related to the screen settings in
the display. It specifically does not include any descriptions of how the commands are communicated using any particular video interface protocol.
The revision also corrects known errors, clarifies the use of certain VCP codes, includes new definitions for some
VCP codes, and introduces new codes. It requires that backward compatibility be maintained with the previously issued MCCS V2.
A summary of the MCCS Version 2.2 specification can be viewed, and the full document purchased, at

New VESA® Direct Drive Monitor Panel Standard Set; Defines Minimum Functionality and Connector Configuration
Milpitas, Calif., Mar. 23, 2009 – The Video Electronics Standards Association (VESA) today released a new standard
that introduces a stand-alone Direct Drive Monitor (DDM) Panel with DisplayPort™ interface. The new standard defines all requirements for a Standard Direct
Drive Monitor Panel connection using DisplayPort, along with the panel electronics. The parameters in the standard can be used for any standard sized panel
using DisplayPort TCON with monitor electronics.
Based on the DisplayPort interface, the standard specifies a connector configuration, along with its mechanical
dimensions and pin assignments. It also details the minimum functionality for DDM display panels. Other VESA standards are used for configuration management
and operation.
The new DDM standard eliminates unnecessary duplication of complex electronics that are incorporated into displays now
to let them mimic older CRT monitors and enable backward compatibility with any graphics subsystem. Duplication of scaling, color dithering, and other functions
in the graphics hardware increases cost; eliminating duplication reduces costs and increases the reliability of the DDM display.
The standard specifies the connector and pin assignments to be used on panels for direct drive display applications.
DDM Displays do not have complex timing or internal display controllers but instead connect directly to the graphics subsystems and convey native timing to the
graphics subsystem for correct configuration.
The VESA DDM DisplayPort panels will use the same physical connector as VESA Standard LVDS panels. To ensure the panels
will not accidentally be connected to LVDS sources or standard DisplayPort sources, panels conforming to the specification will display a warning label or
engraving on the chassis.
The Direct Drive Monitor standard can be downloaded free of charge from www.vesa.org or www.displayport.org
VESA® Issues Newest Version of DisplayPort™ Interoperability Guideline;
Designed to Enable DisplayPort and DVI/HDMI Devices to Work Together
Milpitas, Calif., Mar. 12, 2009 – The Video Electronics Standards Association (VESA) today issued the latest version of its DisplayPort Interoperability Guideline, developed to provide guidance for achieving
Interoperability between DisplayPort™ and other display interfaces using cable adaptors.
Interoperability Guideline version 1.1a builds on the original document released in mid-2007, which is designed to serve
market requirements for establishing interoperability between DisplayPort devices and DVI 1.0/HDMI-compatible devices.
There is industry interest in establishing a means for achieving interoperability between DisplayPort Devices and DVI
1.0/HDMI compatible Devices. For example, it is desirable to have the ability to connect a cable between a DisplayPort Source Device and a DVI 1.0/HDMI Sink
Device (or vice versa) and have the devices interoperate. This interoperability cannot currently be accomplished at the specification level, but can be
accomplished at the product level for products that are compliant with both DisplayPort 1.1a and either the DVI 1.0 or HDMI specification.
“Enabling device interoperability by connecting a cable between a DisplayPort Source Device and a DVI 1.0/HDMI Sink
Device is a significant benefit across the industry,” said Bill Lempesis, VESA executive director. “Our guidelines are designed to enable the devices to work
together and the revisions and updates that are presented in version 1.1a reflect the experience of our users in implementing the guidelines.”
The Interoperability Guideline can be downloaded free of charge from www.vesa.org or www.displayport.org
Embedded DisplayPort™ Standard Ready from VESA®; Defines Feature Set of Embedded Versions for Notebook PCs, Other Applications
Milpitas. Calif., Feb. 23, 2009 – A new standard issued by The Video Electronics Standards Association (VESA) provides a
complete definition of requirements and options for a standard panel interface for embedded display applications.

specifications covering the DisplayPort Physical Layer (PHY) and DisplayPort Link Layer, which provide test procedures designed to ensure compliance of DisplayPort
devices and interoperability between them.
The VESA DisplayPort PHY Compliance Test Specification Version 1.1 details the required tests, test methods, conditions,
and equipment requirements for interoperability. The specification establishes a superset test regimen for the determination of compliance of DisplayPort devices,
segmented into source, receiver, copper cable, hybrid devices, and tethered devices. It stipulates the high level requirements for each test for device setup,
test equipment, signal conditions, methodology and device to test instrument connectivity. It also incorporates test limits for the measurement results.
The VESA DisplayPort Link Layer Test Specification Version 1.1 defines a compliance test procedure and criteria (or masks)
to maximize interoperability of DisplayPort devices at the Link Layer and above. It specifies the Link Layer (and above) tests for source, sink and branch devices.
“These new PHY and Link Layer Test Specifications will enhance and expand our compliance and interoperability efforts,
which are vital to the long term success of DisplayPort,” said Bill Lempesis, VESA executive director. “Products that meet the requirements are certified,
assuring users and customers that DisplayPort products meet the highest levels of compliance and interoperability.”
