DDC Options
From the Administration menu, the DDC Options page can be displayed. DDC enables the video source to get EDID information
from the display device. This enables the video source to automatically select the optimal resolution for the display by receiving,
at power up, information from the display device concerning its resolution specifications.
Figure 24- DDC Options page
EDID information can be provided to the video source by the VEEMUX as follows:
Default1- The video source on the input port will receive EDID information from the VEEMUX through an onboard table of values.
The values for Default 1 support computer monitors.
Default2- The video source on the input port will receive EDID information from the VEEMUX through an onboard table of values.
The values for Default 2 support televisions.
Load from Output- select the radio button for this option and enter the output number associated with the monitor that the CPU
should get its EDID information from.
Direct- (available in 4x4 and 8x8 models only) The video source on an input will get EDID information from the video display
device that is first connected to the output, regardless of what other display devices are also connected to the video source. If
the first output is switched to another input, the video source will look to the other connected outputs to get EDID information from,
searching from the lowest numbered output port first.
For example: The video source on input 1 is connected to output 8, then 4, then 2, and then 5 for a total of 4 display
connections. If output 8 is switched to another video source, the video source on input 1 will then get EDID information
from output 2.
Mixed- The video source on the input port will receive EDID information that is common to the outputs selected on the “DDC Mix”
page (page 42) for that input.
Update DDC setting on Power cycle and on Load Stored Switch Config- place a checkmark in the box to refresh DDC data
stored in the VEEMUX each time the VEEMUX is power-cycled or when a stored configuration (page 33) that includes this DDC
configuration is loaded. The DDC data will be updated based on the configuration on this page.
Save and Store to Switch Configuration 0- press to save the DDC Configuration settings to Switch Configuration 0 so that when
the VEEMUX is power cycled and the “Update DDC setting on Power Cycle….” (above) is checked, the DDC Configuration will be
loaded as configured above.
Modify Default1 DDC with User1 DDC- click this button to load the EDID information to “Default1” from the video display
connected to Output 1
Modify Default1 DDC with Factory Default- click this button to restore “Default1” with factory supplied EDID information
Once any changes are made, press “Save” to have them take effect.
