The Great PC to TV Connection (Worldofcables)
Worldofcables (Santa Clara- CA) & Cablewholesale -Playing computer games, watching downloaded movies or anything else done on a computer is great. Wouldn’t it be better if you could use your new 42″ HDTV as a display instead of your little 17″ computer monitor? Its difficult to resist that urge, but connecting a computer to a TV isn’t always as easy as you might hope. In fact, “How can I connect my computer to my television” is one of the most common questions we receive on our technical support lines. Sometimes, it can be as simple as a single cable, but more often than not, connecting these two devices requires a converter box. In this article, we’ll look at all the options for connecting a PC to a television.
Computers with a VGA output
Assuming your computer has a VGA input, then the easiest connection is if your TV also has a PC VGA input. This would be the standard VGA video output from a computer to the same connection on a TV. Many newer televisions, in particular HDTV’s, have this connection. If your TV does have this input, then a simple Super VGA cable (male to male) will do the trick, and will give you the best possible video quality.
If your television does not have a VGA input, your next best bet is if the television has a component video input. If so, a converter box is available (our part number 40H1-50200) that will convert your VGA signal into Component video. (Note that this part only works in one direction; if you needed to convert component video back to VGA, you would want part number 40H1-50300). Component video gives you the same high quality picture as VGA, so it’s the next best choice after VGA for converting a computer signal. (The other two video options we list below, composite video and s-video, will not deliver as clean a picture, and should only be used when neither VGA nor component video are available.)more on www.worldofcables.com
VGA to Component Converter
Converting VGA to component video often causes confusion for customers, who wonder why a converter box is needed. This confusion is because there is also a cable out there that looks as though it would do the same job as the VGA to component video conversion box. VGA to component video cables, such as the one shown to the right, are often mistakenly purchased in an attempt to connect a computer’s VGA source to a component video display.

VGA to component cable
The reason why this cable will not work to convert a computer’s VGA signal into component video is because the VGA signal and component video signal are very different video signal types. It takes more than a simple cable to convert between the two. This cable is actually designed for use with certain projectors that have a 15-pin VGA connection that is specially designed to be capable of accepting the component video signal (often referred to as a Y/Pb/Pr signal). This design is so that the projector doesn’t have to have separate jacks for both component video and VGA, thus saving space (and money). This same dual-purpose connector is also found on certain HDTV set-top boxes.
If you have an older television set that has neither a VGA nor a component video input, then it will most likely have a composite video (yellow RCA jack) and / or an S-video connection. To convert your VGA into Composite video or S-video, our part number 41CV-50220 will do the trick. This box gives you the option of converting your computer’s VGA signal into either Composite or S-video. It also has an additional VGA output if you would like to have a VGA monitor and your TV hooked up at the same time. More on www.worldofcables.com
Computers with a DVI output
Any new HDTV out recently will have a DVI or HDMI input on it as its digital connection. If this is the case for you, connecting your PC to the television is simply a matter of choosing either a DVI cable (if your TV has a DVI input port on it) or a DVI to HDMI cable (if your TV has an HDMI port on it).
So what do you do if your television is not equipped with DVI or HDMI ports? Well, as it turns out, most computer video cards with DVI on them can be readily adapted to a VGA connection using a simple DVI to VGA adaptor to convert the DVI port into a VGA port. From there, you can simply follow the instructions above for connecting a VGA output to your TV. More on www.worldofcables.com
What about Audio?
All of the options listed above are for video signals only. Audio will have to be run separately. Fortunately, unlike the video hookup, connecting up audio between a computer and a TV is pretty straightforward. Computer sound cards have a 3.5mm (sometimes also referred to as a 1/8 inch) connection. This is the same connection you would find on headphones or computer speakers. That signal is easily converted to a 2 RCA (Red and White) stereo connection, which can be plugged into the back of your TV, or the back of your receiver if you have one. Worldofcables offers two versions of this cable, depending on your needs; our standard quality and premium quality 3.5mm to two RCA cables are shown in the pictures on the right.
