DVI Input/Output Boards
Matrix Switchers and EDID
Matrix switchers, such as the Optima, provide the ability to route one source signal to many potentially
different types of display devices. As long as the source signal being routed is supported by all of the
display devices, the result would be a good image on each display. If the source signal being routed is not
supported by a display device, the result would be either a badly distorted image or no image at all.
To address these issues, the Optima 8x8 DVI board comes with one EDID EEPROM chip per input
connector, which has been pre-loaded with an AMX AutoPatch EDID set. This EDID set consists of
24 of the most common EDID settings in use today, including all VESA Established Timings
encompassing 8 resolutions at a variety of refresh rates and 8 additional Standard Timings encompassing
8 resolutions and refresh rate combinations (for timing details, see page 115). In many cases, the matrix
switcher can be used straight out of the box with no adjustments (see "Determining the Need for EDID
Programming" on page 121).
The EDID Programmer has been provided for cases where additional in-field programming of the EDID
chips is needed. The EDID Programmer can be used for the following:
Note: Any analysis or editing of the EDID data necessary to support the equipment specific to
your installation will need to be done separately prior to using the EDID Programmer. A variety
of freeware tools can be found on the web to help with these tasks.
Keep in mind that the EDID information for some equipment may not be compatible with the remaining
equipment even with programming. In those cases, the signals will have limited routing options.
Tip: If the signal from some of the equipment can only be routed to part of the destinations due
to incompatible EDIDs, creating a separate virtual matrix (level) for the inputs and outputs
involved can simplify system control.
