The AC-MX44/MX88-AUHD has 29 factory defined EDID settings as well as 3 user memories. You can also choose to read the EDID from any OUTPUT. By default, the Matrix Switch is set to a 1080p EDID for maximum plug and play capability. If you are using 4k/UHD sources you will need to define a 4k/UHD EDID on each input (unless you capture the EDID from the display).

​
​To change the EDID settings:

1. Press and hold (3 seconds) the button for the INPUT that you would like to change
   
2. The UP and DOWN buttons will illuminate. Use these to toggle between the different EDID options. These will be shown on the switch’s LCD display.
   
3. Once you find the EDID that you need, press the INPUT button of the source that you would like to apply the EDID to
   

*NOTE - You may also copy the EDID from any OUTPUT and apply it to any INPUT by selecting “Copy EDID from Output x”. This will copy the EDID from the attached display, store it in “USER EDID 1”, and apply it to the INPUT that you have selected.

These are the pre-defined EDID settings that you can toggle through:
