9.5 VGA
This is used to connectmost computermonitors, known as VGA.
It carries analog RGB signals using the familiar multi-pin “sub-D”
connector located on the back, or side, of all computers. This
connects the computer to monitors, or laptops to projectors for
whole room viewing. This connector carries separated RGB video
information at the desired frame resolution, using analog signals.

signal on a low-cost coax “patch cable”.
