Older Macs could detect something connected via S-Video and gave extra 
options in the Monitors or Displays control panel to configure the 
output.  Maybe it's detecting a change in resistance on ground?

Newer macs use S-Video to X (DVI, ADC, Displayport, etc) adaptors so I'm 
not counting them, since the adaptor may have a way of signalling or 
identifying itself.
