Note 1: Normally linked to pin 10 (0V) in the cable or in the monitor.
Note 2: A NEC Multisync II monitor comes supplied with a 9-way connector on the
computer end of the cable, and an adaptor which allows you to connect this to the 15-
way connector on the computer.
Multiscan monitors that have a 15-way connector are usually wired with the ID bits
indicating either a VGA or SVGA monitor. In this case the system software will display
a VGA mode 27.
