Question regarding MSV-104B, the VGA Video Signal Splitter. Monitor 1
indicates 'DDC PnP Port,' what is the purpose of that port?
Port 1 is labeled "DDC PnP Port" because that is the port the splitter will
read the DDC signal and/or Plug-n-Play Compatibility from. The other ports
take their cues from Port 1.
If you plug a DDC compatible monitor into Port 1, all other monitors must be
able to support the highest resolution of the monitor connected to Port 1.
DDC stands for Display Data Channel, and is a handshake standard that enables
a video monitor to relate information (such as maximum resolution and depth) to
a video card source. This allows the source and display to synchronize themselves
for optimal display settings.
