4.5. The EDID Memory of a Matrix
The EDID memory is non-volatile and consists of four blocks, each for a different purpose. These blocks are:
▪
Factory preset EDIDs
▪
User saved EDIDs
▪ Dynamic EDIDs (EDID of last connected sink on a specific output port)
▪ Emulated EDIDs (EDID currently emulated on a specific input port)
EDIDs are numbered from 1 in each block, and they can be referred to as the first letter of the block name and
the number of the desired EDID. For example, F02 refers to the second factory preset EDID and D15 refers to
the display device's EDID on output 15.
Dynamic and emulated EDID blocks' size adapts to the frame size. The memory structure is as follows:
▪ F01..F99 .................Factory Preset EDIDs (not editable)
▪ U01..U50 ................User programmable memories
▪ D01..Dxx .................Last attached monitor's EDIDs (outputs)
▪ E01..Exx .................Emulated EDIDs (inputs)
All EDIDs (including factory preset; user programmable memories; EDID at other inputs; and EDID at outputs)
can be switched and emulated at any of the inputs.
ATTENTION!
The attached monitor's EDID is stored automatically until a new monitor is attached to that
particular output. When powering the unit off, the last attached monitor's EDID remains in non-volatile
memory even is the monitor is unconnected.
INFO:
MX-CPU2 can handle both 128 Byte EDID and 256 Byte extended EDID structures.

4.5.1. EDID Types
Most of the factory preset EDIDs include only one resolution. This is to force the connected source to
give a signal with the needed resolution. However, there are Universal EDIDs as well, which allow many
resolutions. The factory EDIDs are divided into groups regarding their type. Some EDIDs are supporting DVI
only, some support HDMI, and some are for analog VGA signals. Also, there are some EDIDs for Dual Link
DVI resolutions. See the list of factory EDIDs in the
DVI EDIDs do not support audio. The Universal DVI EDID indicates support for many PC (VESA) resolutions.
HDMI EDIDs support embedded audio. These EDIDs have PCM stereo audio format enabled. To allow other
audio formats like Dolby and DTS, special EDIDs have to be used. There are three Universal HDMI EDIDs that
include the same resolutions, but support different capabilities.

Analog EDIDs can be used for input ports that have a VGA (RGBHV) source.
Dual Link DVI EDIDs do not support audio. Use only for Dual Link ports.
4.6. Audio Options
Certain I/O boards have extended audio options thanks to the additional auxiliary audio ports. These ports
can be configured as input or output ports. This section presents the capabilities of this audio add-on
feature.
