ServSwitch 4site Flex also uses these entries to distinguish between confusable analog input video signals. The following groups of analog input signals are difficult to distinguish automatically:
WUXGA 1920x1200 60 Hz
UXGA 1600x1200 60 Hz
UXGA 1600x1200 60 Hz with reduced blanking
WUXGA 1920x1200 50 Hz
UXGA 1600x1200 50 Hz
UXGA 1600x1200 50 Hz with reduced blanking
SXGA+ 1400x1050 60 Hz
WSXGA 1680x1050 60 Hz
XGA 1024x768 60 Hz
WXGA 1280x768 60 Hz
WXGA 1360x768 60 Hz
If you experience problems with the automatic input detection of an analog input signal in these groups, you can overwrite the automatic detection by programming the expected video signal into the input EDID.
Use the arrow keys to navigate to the first video mode entry and press ENTER/SELECT to open the window with a list of selectable video modes.
In this window, use the arrow keys to select the desired line in the list shown on the right and press ENTER/SELECT for the video format.
Use the arrow keys 
to navigate to the second video mode entry, and press ENTER/SELECT to open the window with a list of selectable video modes.
Use the arrow keys 
to navigate to “Signal“ and press ENTER/SELECT to switch between analog or digital. This setting specifies whether the EDID should identify the ServSwitch 4site Flex as an analog or digital device. Usually it is safe to leave this setting at“digital.”
Use the arrow keys 
to navigate to the following write options:
•WRITE: Save the changes in the current input EDID.
•WRITE TO ALL INPUTS: Save the changes to all four input EDIDs.
