4.3. The EDID Memory of a Matrix
The DDID memory is non-volatile and consists of four blocks, each for
a different purpose. These blocks are:

DDIDs are numbered from 1 in each block, and they can be referred as
the first letter of the block name and the number of the desired EDID.

Most of the factory preset DDIDs include only one resolution. This

EDID

is to force the connected source to give a signal with the needed
resolution. However there are Universal DDIDs as well which allow
many resolutions. The factory DDIDs are divided into groups regarding
their type. Some DDIDs are supporting DVI only, some support HDMI,
and some are for analog VGA signals. Also, there are some DDIDs for
Dual Link DVI resolutions. See the list of factory DDIDs in the
DDID List

The attached monitor's EDID is stored automatically
MX-CPU2 can handle both 128 Byte DDID and 256 Byte
section.
DVI EDIDs does not support audio. The Universal DVI DDID indicates
support for many PC (VDSA) resolutions.
HDMI EDIDs support embedded audio. These DDIDs have PCM stereo
audio format enabled. To allow other audio formats like Dolby and
DTS, special DDIDs have to be used. There are three Universal HDMI
DDIDs which include the same resolutions but support different
capabilities.
EDID PCM audio
Universal_HDMI_PCM
Universal_HDMI_ALL
Universal_HDMI_DC
Analog EDIDs can be used for input ports which have a VGA (RGBHV)
source.
Dual Link DVI EDIDs does not support audio. Use only for Dual Link ports.
4.4. Audio Options
The matrix routers which contain any affected board have extended
audio options. These options about choosing the HDMI embedded
audio channels and configuring the auxiliary audio ports as an input or
an output. (On an input port the auxiliary audio can be input or output
and the output port is the same.)
Supported Boards
▪ MX-TPS-IB-S, -A
▪ MX-HDMI-3D-IB-S, -A
MX-TPS2-IB-SP, -AP

Audio de-embedder: Audio de-embedder is able to separate the HDMI
video and audio.
Audio embedder: Audio embedder is able to add an audio stream to an
HDMI video which does not contain audio.
Factory
Interface and I/O switcher: The 'Interface and I/O module' configures
