DIY VGA to TV Cable
Nov 23, 2018

VGA cables use a D-sub connector with 15 pins, and carry analog video signals for red, green, and blue color channels (RGB), horizontal and vertical sync, and miscellaneous monitor data. Many high-definition televisions support VGA connections to computers, and only require a male to male cable. Televisions and display devices that lack a VGA port may still be able to receive a signal from a computer with an appropriate adapter.


VGA to DVI

A television with a backwards compatible Digital Video Interface (DVI) port can be driven by a VGA cable with a DVI adapter. These adapters are often included for free with monitors and video cards, but can be replicated by connecting the correct pins. DVI-Integrated and DVI-Analog cables both use special pins to carry a VGA's analog RGB signal. 


VGA to Component RCA

If a display device has support for Component RCA, a VGA to RCA adapter can produce a quality picture. Component video is converted from RGB and split into three channels: image brightness, or luminance; the difference between blue and luminance, and difference between red and luma. Some display devices may support both signals, and video cards can occasionally choose between an output of RGB and component video. Attach an RCA plug to each of the three VGA color signals.
