This page helps you find the cables you need to connect a personal computer to a television.

Background

In 1987, IBM released the Video Gate Array (VGA) card, which could generate a color video signal with enhanced definition. But for about two decades afterward, connecting a PC to a TV to a television was considered a "hard problem". Most TVs were boxy CRT SDTVs (cathode ray tube standard-definition televisions). These required a "scan converter" to turn the EDTV (enhanced-definition television) or HDTV (high-definition television) signal from a monitor into an SDTV signal that the TV can use. But starting around the early 2000s, video cards using an NVIDIA or ATI chipset began to incorporate a TV output with a scan converter right on the card. Furthermore, as of 2008, people are replacing their SDTV sets with HDTV sets, which have the same ports on the back as a PC monitor.

First find the video output connectors on the back of your computer and your monitor or TV set.

HDTV

Your computer Your monitor Required cable
VGA VGA VGA cable
DVI (DVI-I) VGA DVI-to-VGA cable
DVI DVI DVI cable
DVI HDMI DVI-to-HDMI cable

SDTV

Do not confuse composite (yellow) connections with audio (white or red) connections.

Your computer Your monitor Required cable
S-Video (4 or 7 pin) S-Video (4 pin) S-video cable
S-Video Composite S-Video cable
Composite Composite RCA cable
VGA Composite Scan converter and RCA cable
VGA S-Video Scan converter and S-Video cable
DVI-I Composite Scan converter, DVI-to-VGA cable, and RCA cable
DVI-I S-Video Scan converter, DVI-to-VGA cable, and S-Video cable

If you need a scan converter, I've had decent results with the SW-22050 from Sewell.
