How to Connect an RGB TTL Monitor to a VGA

Updated February 21, 2017

A transistor-transistor logic (TTL) monitor is a digital circuit used on video display hardware, such as computer monitors. The monitor, like most other electronic displays, creates all colours through the electronic colour spectrum, which uses red, green and blue (RGB) to produce all other colours, with a provided video signal. This video signal is input to the monitor through a VGA cable connection. This cable is rectangular in shape, and is made up of nine different small connector pins. Because all computer systems have a VGA video output, you shouldn't have trouble hooking up the monitor to your computer.

Insert the VGA cable into the VGA port on the computer system.

Tighten the screws on either side of the connection by hand turning both to the right. This secures the cable connection to the computer.

Connect the opposite end of the cable into the VGA connection port on the TTL monitor.

Turn the screws on this end of the cable to secure the connection to the monitor. Power on the monitor and the video signal from the computer appears on the display screen.
