VESA Mon= itor Control Command Set (MCCS)

Standard=

Version 2

October 17, 2003

Purpose

The purpose of this st= andard is to define a universal set of commands used to control the screen setting= s of displays, which can be used within any communication protocol established between the host and display.

Summary

This document describes the standardized list of commands and controls to be use= d in identifying and controlling the display by means of an application running = on the host. The list of commands and controls is kept to a minimum, while supporting the control of virtually all parameters related to the screen settings in the display. It does not describe how these commands are packag= ed in a particular interface protocol.

Further, the document assumes the interface supporting the display can issue an unsolicited attention call (interrupt) to alert the host that something has happened outside the control of the host. The targeted display devices are displays attached to the video output of PCs and workstations; however, it = is not restricted to this area.

= Revision History:

Version 2 of the MCCS standard is a maj= or update, in particular to provide support for flat panel displays and the anticipated VESA DPVL (Digital Packetized Video= Link) Standard. It extends the scope and range of controls for TV functions and introduces commands to permit individual control of multiple windows on the desktop. Many of the existing= VCP codes have expanded functionality and/or better definition. To ensure that = the requirements of compatibility and an intuitive user interface can be readily achieved, support for two commands (see section 5) is a requirement for compliance with MCCS version 2.

Additionally, new classes of VCPs associated with asset management, secondary (information / status) displays and remote program calls to the display processor are introduced. These are expected to become significant to the industry over time.

This version also has several format ch= anges with the VCPs split into a number of logical gr= oups each with its own table (section 6) and a comprehensive index (section 7) of all commands and the associated table.

1 OVERVIEW

1.1 = Summary

This document describes the standardized list of control commands that may be us= ed to control a display by means of an application running on the host. This concept is referred to a ‘virtual control panel’ or VCP.

The list of commands and controls is kept to a minimum while supporting the con= trol of all common parameters related to the image settings on the display and o= ther common features.

It does not describe how these commands are used with a particular interface protocol nor does this document describe the way a particular protocol quer= ies and changes the settings of the controls, see appropriate interface standard for these details e.g. VESA DDC/CI standard.

A companion document will be maintained, called MCCSupx.pdf. This will include such things as correction of known errors, extensions of = VCP code value definitions and new VCP codes proposed for inclusion in the next MCCS revision.

1.2 = Background

Due to the emergence of new digital interfaces on hosts (PCs and Workstations)<= span class=3DGramE>, it has become possible to control the settings of the display by means of an application running on the host.

Historically, displays have provided hardware control panels (on screen display or OSD) to accomplish these device adjustments. Using the computer in addition to these manual controls increases user convenience and provides the opportunity for= a standardized user interface regardless of the manufacturer of a particular display.

Although there are different ways to set up the communication, the basic content of = the information communicated can be standardized offering everyone the same experience in accomplishing the same goal.

1.3 = S= tandard Objectives

The standard aims to provide for a standard list of display controls and comman= ds, which can be used irrespective of the interface used to support the necessa= ry communication between the host and the display.

The list is chosen to be the minimum list necessary to support virtually all parameters related to the image settings. A number of codes are available f= or manufacturers to use where they have design features not covered by the standard codes.
