OSD - COMPUTER - EDID/DDC
EDID/DDC (continued)
In this window two freely selectable video modes can be programmed in the input EDID visible to the connected
computer at the input port.
It is recommended to program the preferred video modes for the connected signal source.
SPLITMUX-DVI-4 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 60Hz
UXGA 1600x1200 60Hz with reduced blanking
WUXGA 1920x1200 50 Hz
UXGA 1600x1200 50Hz
UXGA 1600x1200 50Hz with reduced blanking
SXGA+ 1400x1050 60Hz
WSXGA 1680x1050 60Hz
XGA 1024x768 60Hz
WXGA 1280x768 60Hz
WXGA 1360x768 60Hz
If you experience problems with the automatic input detection of an analog input signal in these groups you can
ovewrite the automatic detection by programming the expected video signal into the input EDID.
Note:
Please keep in mind that this setting will overwrite the automatic analog input mode detection. If you
connect a different video source, or change the video mode from the PC, you may need to change
this setting again to get correct results. For the detection of digital input signals this setting has no effect.
