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

Background

In 1987, IBM released the Video Graphics Array (VGA) card, which could generate a color video signal with 480p enhanced definition. But for about two decades afterward, connecting a PC to a TV was considered a "hard problem". Most TVs of the time 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 a chipset made by NVIDIA or ATI 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.

Video connector

There are several kinds of video connectors commonly used in consumer electronics. In roughly increasing order of video fidelity:

  1. RCA connector: a yellow one usually carries composite video
  2. S-Video connector: round, 4 or 7 pins, carries brightness and color on separate pairs of wires
  3. VGA connector: DE-15, carries progressive RGB video
  4. DVI connector: D-shaped, longer than VGA, can carry digital (DVI-D) and analog (DVI-A) video signals in a single integrated (DVI-I) connector
  5. HDMI connector: carries DVI-D video and (optional) digital audio on on a thinner connector

Find the video output connectors on the back of your computer and your monitor or TV set. Then compare them to the pictures in the Wikipedia articles to see what connectors you have.

  • DVI ports come in two flavors: DVI-D, with a flat pin on one side, and DVI-I, with a longer flat pin surrounded by small pins.

DVI-D (the D stands for digital) has only digital signals; DVI-I (the I stands for integrated) also carries analog VGA signals. DVI-to-VGA cables work only with DVI-I ports; DVI-D ports work with either.

Some Mac computers have miniature DVI or miniature DisplayPort connectors. Apple dealers sell adapters from both to DVI and VGA.

SDTV

Do not confuse RCA connectors that carry composite video (yellow) with those carrying audio (white or red), or you'll hear a horrible buzzing noise from your TV's speakers.

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

It may be hard to find a scan converter in a brick-and-mortar retail store. I've had decent results with the SW-22050 from Sewell ($34.95).
