'''Extended Display Identification Data''' ('''EDID''') and '''Enhanced EDID''' ('''E-EDID''') are [[metadata]] formats for [[display device]]s to describe their capabilities to a video source (e.g., [[graphics card]] or [[set-top box]]). The data format is defined by a standard published by the [[Video Electronics Standards Association]] (VESA).

The EDID data structure includes manufacturer name and serial number, product type, [[phosphor]] or [[filter (optics)|filter]] type (as [[chromaticity]] data), timings supported by the display, display size, [[luminance]] data and (for digital displays only) [[pixel]] mapping data.

[[DisplayID]] is a VESA standard targeted to replace EDID and E-EDID extensions with a uniform format suited for both PC monitor and consumer electronics devices.

==Background==
{{primary sources|section|date=February 2013}}

EDID structure (base block) versions range from v1.0 to v1.4; all these define upwards-compatible 128-[[byte]] structures. Version 2.0 defined a new 256-byte structure but it has been deprecated and replaced by E-EDID which supports multiple extension blocks.{{citation needed|date=October 2011}} [[HDMI]] versions 1.0–1.3c use E-EDID v1.3.<ref>{{cite web |url=http://www.microprocessor.org/HDMISpecification13a.pdf |archive-url=https://web.archive.org/web/20160305072940/http://www.microprocessor.org/HDMISpecification13a.pdf |url-status=dead |archive-date=5 March 2016 |title=High-Definition Multimedia Interface Specification Version 1.3a |date=10 November 2006 |access-date=2017-04-01 }}</ref>

Before [[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. Some [[VGA connector]]s in personal computers provided a basic form of identification by connecting one, two or three pins to ground, but this coding was not standardized.

This problem is solved by EDID and DDC, as it enables the display to send information to the graphics card it is connected to. The transmission of EDID information usually uses the [[Display Data Channel]] protocol, specifically DDC2B, which is based on [[I²C]]-bus (DDC1 used a different serial format which never gained popularity). The data is transmitted via the cable connecting the display and the graphics card; [[VGA]], [[DVI]], [[DisplayPort]] and [[HDMI]] are supported.{{citation needed|date=October 2011}}

The EDID is often stored in the monitor in the firmware chip called serial [[EEPROM]] (electrically erasable programmable read-only memory) and is accessible via the I²C-bus at address {{code|0x50}}. The EDID PROM can often be read by the host PC even if the display itself is turned off.

Many software packages can read and display the EDID information, such as read-edid<ref>{{cite web |url=http://www.polypux.org/projects/read-edid/ |title=read-edid |website=Polypux.org |access-date=2017-04-01 |archive-date=2010-12-11 |archive-url=https://web.archive.org/web/20101211003405/http://www.polypux.org/projects/read-edid/ |url-status=live }}</ref> for Linux and DOS, PowerStrip<ref>{{cite web |url=http://www.entechtaiwan.com/util/ps.shtm |title=Utilities &#124; PowerStrip |publisher=EnTech Taiwan |date=2012-03-25 |access-date=2017-04-01 |archive-date=2011-03-08 |archive-url=https://web.archive.org/web/20110308182859/http://entechtaiwan.com/util/ps.shtm |url-status=live }}</ref> for [[Microsoft Windows]] and the [[X.Org Server]] for [[Linux]] and [[Berkeley Software Distribution|BSD unix]]. [[Mac OS X]] natively reads EDID information and programs such as SwitchResX<ref>{{cite web |url=http://www.madrau.com/ |title=SwitchResX - The Most Versatile Tool For Controlling Screen Resolutions On Your Mac |website=Madrau.com |access-date=2017-04-01 |archive-date=2009-02-08 |archive-url=https://web.archive.org/web/20090208214058/http://madrau.com/ |url-status=live }}</ref> or DisplayConfigX<ref>{{cite web |author=Harald Schweder |url=http://www.3dexpress.de/ |title=DisplayConfigX |website=3dexpress.de |date=2003-02-11 |access-date=2017-04-01 |archive-date=2011-07-18 |archive-url=https://web.archive.org/web/20110718193430/http://www.3dexpress.de/ |url-status=live }}</ref> can display the information as well as use it to define custom resolutions.

E-EDID was introduced at the same time as [[Display Data Channel#E-DDC|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). Data fields for preferred timing, range limits, and monitor name are required in E-EDID.  E-EDID also adds support for the Dual [[Generalized Timing Formula|GTF]] curve concept and partially changed the encoding of aspect ratio within the standard timings.

With the use of extensions, E-EDID structure can be extended up to 32 KiB, because the E-DDC added the capability to address multiple (up to 128) 256 byte segments.

*September 2006, E-EDID Standard Release A – introduce E-EDID v1.4, based on EDID v1.4.

==Limitations==
Some graphics card drivers have historically coped poorly with the EDID, using only its standard timing descriptors rather than its Detailed Timing Descriptors (DTDs).  Even in cases where the DTDs were read, the drivers are/were still often limited by the standard timing descriptor limitation that the horizontal/vertical resolutions must be evenly divisible by 8.  This means that many graphics cards cannot express the [[native resolution]]s of the most common [[widescreen]] [[flat-panel display]]s and [[LCD television|liquid-crystal display TVs]].  The number of vertical pixels is calculated from the horizontal resolution and the selected [[aspect ratio (image)|aspect ratio]]. To be fully expressible, the size of [[widescreen]] display must thus be a multiple of 16×9 pixels. For 1366×768 pixel [[Wide XGA]] panels the nearest resolution expressible in the EDID standard timing descriptor syntax is 1360×765 pixels, typically leading to 3-pixel-thin black bars. Specifying 1368 pixels as the screen width would yield an unnatural screen height of 769.5 pixels.

Many [[Wide XGA]] panels do not advertise their native resolution in the standard timing descriptors, instead offering only a resolution of 1280×768. Some panels advertise a resolution only slightly smaller than the native, such as 1360×765. For these panels to be able to show a [[pixel perfect]] image, the EDID data must be ignored by the display driver or the driver must correctly interpret the DTD and be able to resolve resolutions whose size is not divisible by 8. Special programs are available to override the standard timing descriptors from EDID data. Even this is not always possible, as some vendors' graphics drivers (notably those of [[Intel]]) require specific registry hacks to implement custom resolutions, which can make it very difficult to use the screen's native resolution.<ref>{{cite web

It contains updates to CTA 3D Audio, and clarifications on Content Type Indication, and on 4:2:0 support for VTDBs and VFDBs. It also introduces a new Product ID Data Block, to replace the Manufacturer PNP ID in the first block of the EDID, since the UEFI is phasing out assigning new PNP IDs.

===CTA Extension Block===

Version 1 of the extension block (as defined in CEA−861) allowed the specification of video timings only through the use of 18-byte Detailed Timing Descriptors (DTD) (as detailed in EDID 1.3 data format above).  DTD timings are listed in order of preference in the CEA EDID Timing Extension.

Version 2 (as defined in 861-A) added the capability to designate a number of DTDs as "native" (i.e., matching the resolution of the display) and also included some "basic discovery" functionality for whether the display device contains support for "basic audio", YC<sub>B</sub>C<sub>R</sub> pixel formats, and underscan.

Version 3 (from the 861-B spec onward) allows two different ways to specify digital video timing formats: As in Version 1 & 2 by the use of 18-byte DTDs, or by the use of the Short Video Descriptor (SVD) (see below). HDMI 1.0–1.3c uses this{{which|date=January 2014}} version.

Version 3 also defines a format for a collection of data blocks, which in turn can contain a number of individual descriptors. This Data Block Collection (DBC) initially had four types of Data Blocks (DBs): Video Data Blocks containing the aforementioned Short Video Descriptor (SVD), Audio Data Blocks containing Short Audio Descriptors (SAD), Speaker Allocation Data Blocks containing information about the speaker configuration of the display device, and Vendor Specific Data Blocks which can contain information specific to a given vendor's use. Subsequent versions of CTA-861 defined additional data blocks.

Once one data block has ended, the next byte is assumed to be the beginning of the next data block. This is the case until the byte (designated in byte 2, above) where the DTDs are known to begin.

=== CTA Data Blocks ===

As noted, several data blocks are defined by the extension.

==== Video Data Blocks ====

The '''Video Data Blocks''' will contain one or more 1-byte Short Video Descriptors (SVDs).

Notes: Parentheses indicate instances where pixels are repeated to meet the minimum speed requirements of the interface. For example, in the 720x240p case, the pixels on each line are double-clocked. In the (2880)x480i case, the number of pixels on each line, and thus the number of times that they are repeated, is variable, and is sent to the DTV monitor by the source device.

Increased Hactive expressions include “2x” and “4x” indicate two and four times the reference resolution, respectively.

Video modes with vertical refresh frequency being a multiple of 6{{nbsp}}Hz (i.e. 24, 30, 60, 120, and 240{{nbsp}}Hz) are considered to be the same timing as equivalent NTSC modes where vertical refresh is adjusted by a factor of 1000/1001. As [[VESA DMT]] specifies 0.5% pixel clock tolerance, which 5 times more than the required change, pixel clocks can be adjusted to maintain NTSC compatibility; typically, 240p, 480p, and 480i modes are adjusted, while 576p, 576i and HDTV formats are not.

* The EIA/CEA-861 and 861-A standards included only numbers 1–7 and numbers 17–22 (only in -A) above (but not as short video descriptors which were introduced in EIA/CEA-861-B) and are considered primary video format timings.
* The EIA/CEA-861-B standard has the first 34 short video descriptors above. It is used by HDMI 1.0–1.2a.
* The EIA/CEA-861-C and -D standards have the first 59 short video descriptors above. EIA/CEA-861-D is used by HDMI 1.3–1.3c.
* The EIA/CEA-861-E standard has the first 64 short video descriptors above. It is used by HDMI 1.4–1.4b.
* The CTA-861-F standard has the first 107 short video descriptors above. It is used by HDMI 2.0–2.0b.
* The CTA-861-G standard has the full list of 154 (1–127, 193–219) short video descriptors above. It is used by HDMI 2.1.

The remainder of the Vendor Specific Data Block is the "data payload", which can be anything the vendor considers worthy of inclusion in this EDID extension block. For example, IEEE registration number {{code|00 0C 03}} means this is a "HDMI Licensing, LLC" specific data block (contains HDMI 1.4 info), {{code|C4 5D D8}} means this is a "HDMI Forum" specific data block (contains HDMI 2.0 info),  {{code|00 D0 46}} means this is "DOLBY LABORATORIES, INC." (contains Dolby Vision info) and {{code|90 84 8b}} is "HDR10+ Technologies, LLC" (contains HDR10+ info as part of HDMI 2.1 Amendment A1 standard<ref>{{cite web |title=edid-decode.git - edid-decode main repository |url=https://git.linuxtv.org/edid-decode.git/commit/?id=dc8afbf7e3001587e27695288ff8c259249256b1 |website=git.linuxtv.org |access-date=2 April 2020 |archive-date=1 August 2020 |archive-url=https://web.archive.org/web/20200801131640/https://git.linuxtv.org/edid-decode.git/commit/?id=dc8afbf7e3001587e27695288ff8c259249256b1 |url-status=live }}</ref>). It starts with a two byte source physical address, least significant byte first. The source physical address provides the CEC physical address for upstream CEC devices. HDMI 1.3a specifies some requirements for the data payload.

Some speaker flags have been deprecated in the SADB, but are still available in the RCDB's SPM. These speakers could not be indicated with a CA value in the Audio InfoFrame, and can only be used with Delivery According to the Speaker Mask, which corresponds to the RCDB only.

==== Room Configuration Data Block ====

The '''Room Configuration Data Block''' and '''Speaker Location Data Blocks''' describe the speaker setup using room coordinates.
