EDID (Extended Display Identification Data) is a data structure that is used between a display and a source. This data is used by the
source to find out what audio and video resolutions are supported by the display, from this information the source will discover
what the best audio and video resolutions need to be outputted.
While the objective of EDID is to make connecting a digital display to a source a simple plug and play procedure, issues do arise
when multiple displays or video matrix switching is introduced because of the increased number of variables.
By pre-determining the video resolution and audio format of the sources and display device you can reduce the time needed for
EDID hand shaking thus making switching quicker and more reliable.
Configuration of extender EDID settings can be achieved using the product dip-switches on the SW21AB-V2. EDID dip-switch
settings are shown below.
Note:
You must power cycle the product after making EDID changes. For some sources it may be necessary to power cycle the
source after EDID changes have been made for the source to update its video & audio output settings.
