This information is supplied to help a source optimise its output to give the best quality but also a supported
format to the output screen. EDID is therefore an incredibly useful tool however, it is also the source of many
AV integration issues. For consumer grade products problems are limited as the applications tend to be source
directly to screen but with large AV installations the incorporation of matrices, splitters, repeaters, mixed
screens and sources, EDID management is very likely, if not handled carefully, to cause problems.
HDBaseT point-to-point installations tend to avoid these problems as EDID is passed through the extenders
directly from source to screen as if they were connected by a direct cable. Issues may however arise when
using HDBaseT matrices and/or HDBaseT splitter devices.
Within a screen is usually a EEPROM (electronically erasable programmable read-only memory) device, on
which is stored the raw data of 128 or 256 bytes, as seen in the example above. The HDMI output on a source
has a +5V signal on pin 18, as previously discussed in this manual this is used as part of the hot-plug detect
mechanism, this +5V signal is also used as the power supply for the EEPROM device, this is not always the
case but is common in most screens. When the +5V powers the EEPROM it can then begin outputting data
and this is transmitted to the HDMI source via the DDC clock and data connections, pins 15 and 16
respectively on a HDMI connector. From this point on, even if the screen is not powered on the HDMI source
will have access to the EDID data of the screen.
The raw data, at the bottom of the example above, is the information that is sent from the sink to source device.
The example above is read from a monitor connected to a PC via a display port connection, display port
supports EDID V1.4, which is a 256 Byte raw data exchange. EDID 1.3 is the latest revision supported by HDMI,
this is a 128-byte raw data exchange from sink to source. These 128 bytes are mandatory for any device, the
extension to 256 bytes enables the transmission of extra information and is optional but possible for
manufacturers to include this information in a screens EDID information, this is called E-EDID (enhanced
extended display identification data). This extra 128-byte block contains information such as colour depth
information.
