That is almost certainly setting what type of signal is generated.  Like a TV 
of the same era, the monitor (display) portion doesn't care;  it just displays 
what it is sent.  That is very different from a monitor setting that sets 
either interlaced or non-interlaced.

Some reasons why you might prefer one over the other on the same screen:  
non-interlaced would have a horizontal gap between displayed lines whereas 
interlaced would fill them in.  However, interlaced is more prone to 
flickering, which can be very tiring to the eyes and cause headaches.
