How to Connect an RGB TTL Monitor to a VGA

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.
