NTI VEEMUX DVI VIDEO MATRIX SWITCH
11
DDC Menu
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.
Under the “DDC” menu are five parameters:
1- Chose Input
(Choose Input)
2- All Inputs
3-FacDefault1
4-UsrDefault1
5-ReloadOptn
1) Choose Input
- select the EDID information source for each input individually, or
2) All Inputs
- select EDID information source for all inputs at once.
Within these sections you will need to select between:
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
default 1-
the
inputs will get EDID information from a predefined table in the VEEMUX supporting CPU monitors
default 2-
the
inputs will get EDID information from a predefined table in the VEEMUX supporting televisions
From Out (?)-
select which Output port the Input will get EDID information from regardless of which output it is
connected to
DDC Mix(?)
- select which Input will receive EDID information that is common to the Outputs selected on the “DDC Mix”
page (page 42) for that input
More on “Direct” DDC: 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. The video source gets it EDID from output 8, the first connected output. If output 8 is
switched to another video source, the video source on input 1 will then get EDID information from output 2.
3) FacDefault1
- Select this to use the factory default EDID data for DDC “Default 1” configuration
4) UsrDefault1
- Select this to replace the EDID information stored in the VEEMUX for “Default 1” with the EDID data from the
monitor presently connected to Output 1.
5) ReloadOptn
- Select this and choose to
enable
or
disable
this feature. When enabled, the switch will refresh DDC data
stored in the VEEMUX each time the VEEMUX is power-cycled. The DDC data will be based on the current DDC configuration
settings.
Standby
The fourth option in the main menu is ”Standby”. When Standby is selected, the VEEMUX switch will immediately go into a
power saver mode and the LCD display will go blank. It will remain in this state until
1) any button is pressed on the front panel,
2) the Standby button is pressed on the optional IR Remote Control (page 50), or
3) the “Disable Standby” button is pressed in the web interface (page 45)
