Some graphics card drivers have historically coped poorly with the EDID, using only its standard timing descriptors rather than its Detailed Timing Descriptors (DTDs). September 2006, E-EDID Standard Release A – introduce E-EDID v1.4, based on EDID v1.4.February 2000, E-EDID Standard Release A - introduce E-EDID v1.3 (used in HDMI), based on EDID v1.3.September 1999, E-EDID Standard Release A – introduce EDID v1.3 and E-EDID v1.0, which supports multiple extensions blocks.November 1997, EDID standard version 3 – introduce EDID v1.2 and EDID v2.0.April 1996, EDID standard version 2 – introduce EDID v1.1.August 1994, DDC standard version 1 – introduce EDID v1.0.However, the value is later used by DDDB. Extension defined by monitor manufacturer ( FF): According to LS-EXT, actual contents varies from manufacturer.Display Device Data Block (DDDB) ( FF): contains information such as subpixel layout.Display Transfer Characteristics Data Block (DTCDB) ( A7, AF, BF).Microdisplay Interface Extension (MI-EXT) ( 60).

Localized String Extension (LS-EXT) ( 50).Display Information Extension (DI-EXT) ( 40).Video Timing Block Extension (VTB-EXT) ( 10).Additional Timing Data Block (CEA EDID Timing Extension) ( 02).With the use of extensions, E-EDID string can be lengthened up to 32 KBytes.ĮDID Extensions assigned by VESA E-EDID also supports dual GTF timings and aspect ratio change. Data fields for preferred timing, range limits, and monitor name are required in E-EDID.

Mac OS X natively reads EDID information and programs such as SwitchResX or Displa圜onfigX can display the information as well as use it to define custom resolutions.Į-EDID was introduced at the same time as E-DDC, which supports multiple extensions blocks and deprecated EDID version 2.0 structure (it can be incorporated in E-EDID as an optional extension block). Many software packages can read and display the EDID information, such as read-edid for Linux and DOS, PowerStrip for Microsoft Windows and the X.Org Server for Linux and BSD unix. The EDID PROM can often be read by the host PC even if the display itself is turned off.

The EDID is often stored in the monitor in the firmware chip called serial EEPROM (electrically erasable PROM) and is accessible via the I☬-bus at address 0x50. The channel for transmitting the EDID from the display to the graphics card is usually the I☬-bus, defined in DDC2B (DDC1 used a different serial format which never gained popularity).

Some VGA connectors in personal computers provided a basic form of identification by connecting one, two or three pins to ground, but this coding was not standardized. īefore Display Data Channel (DDC) and EDID were defined, there was no standard way for a graphics card to know what kind of display device it was connected to. Version 2.0 defined a new 256-byte structure but it has been deprecated and replaced by E-EDID which supports multiple extension blocks.
