EDID is a communications protocol or instruction set for the identification of display 
devices to computers using the DDC (Display Data Channel) transmission standard. EDID 
information consists of the resolution, refresh rate, and pixel clock information of a display 
device. You can apply an EDID to a selected input by selecting one of the categories of 
EDID files shown in the table below.
• 
The EDID of the display connected to an output (numbers 1 through the number of 
outputs on your DXP)
• 
One of 28 factory-loaded EDID files (numbers 9 through 36)
• 
One of the four user-defined files, to which you have saved the EDID for the device 
connected to output 1 (numbers 37 through 40)
