DIY VGA to TV Cable

VGA to DVI

A DVI-Analog to VGA adapter

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. Connect the following VGA pins to a DVI connector:

VGA Pin 1 to DVI Pin C1 -- Analog Red
VGA Pin 2 to DVI Pin C2 -- Analog Green
VGA Pin 3 to DVI Pin C3 -- Analog Blue
VGA Pin 13 to DVI Pin C4 -- Analog Horizontal Sync
VGA Pin 14 to DVI Pin 8 -- Analog Vertical Sync
VGA Pins 6, 7, and 8 to DVI Pin C5 -- Return for RGB signals
VGA Pins 13 and 14 to DVI Pin 15 -- Return for Analog Sync

VGA to Component RCA

FEMALE RCA phono plugs

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.

VGA Pin 1 -- Difference between Red and Luma (Pr)
VGA Pin 2 -- Luminance and Sync (Y)
VGA Pin 3 -- Difference between Blue and Luma (Pb)
VGA Pin 6 -- (Pr) Ground
VGA Pin 7 -- (Y) Ground
VGA Pin 8 -- (Pb) Ground
