4.1 DDC Support
When establishing a VGA connection between a PC or laptop and a display device,
a set of parameters known as EDID are exchanged between them, which is carried
over the DDC channel. In some PC graphic cards and laptops, this information
exchange is essential for proper VGA OUT operation.
When the SV-551 is connected to the SV-301 with two STP cables it supports
DDC communication between the connected PC or laptop and the Display device
used, thus ensuring trouble free VGA transmission.
For proper operation of the DDC support, select the appropriate PC IN channel of
the SV-551 before turning on the VGA OUT of your laptop.
1 Connect to the DDC for the transfer of specification data from the display device to the source properties, such as maximum resolution
and color depth. The video card can then use this information to ensure that the user is presented with valid options for configuring the
display
