VS0201 / VS0401 RS-232 Control Tool

DDC

The DDC function, when enabled, lets the VS0201 / VS0401 check the

connected display to provide correct updated EDID information to the source

device so that the display is optimized accordingly. With Dynamic DDC off,

the source devices do not receive updated EDID data, which can cause display

issues. If there is a problem with your display quality, however, it is

recommended that Dynamic DDC be turned off.

On the DDC page, the following functions are possible:

 Select ON to enable Dynamic DDC

 Select OFF to disable Dynamic DDC

 Click SEND to send the command.

DDC Commands

The formula for the DDC command is as follows:

DDC Command + Control (on/off) + [Enter]

For example, to disable Dynamic DDC, type the following:

ddc off [Enter]
