Even if you have a nice television, hooking a PC monitor up to a DVD player is a great way to view your favourite movies from the comfort of your computer desk. Although some technical knowledge of inputs and outputs is helpful, as long as you know how to match cables, getting it all hooked up is a fairly simple process.
Compare your monitor's inputs with your DVD player's outputs. Every monitor will have a VGA input, a standard input that is long and skinny and has several pins; every DVD player has a composite output of red, white and yellow prongs. If these are the only inputs or outputs you can find, you will need an adaptor. However, if you can find DVI or S-video outputs or inputs on both your monitor and your DVD player, you can hook them up directly and skip Step 2.
If you do not have matching inputs and outputs, you will need to find an adaptor that will resolve the different formats. The most common is a composite-to-VGA adaptor, which uses the standard red, yellow and white composite inputs and changes the signal for the standard monitor VGA input. However, it should be noted that the picture quality on a composite VGA adaptor is fairly poor, and if you have a DVI or S-video input on your monitor, it is best to use it.
Connect all the cords. If you are using an adaptor, you will want to connect the DVD player to the adaptor first before plugging the VGA cord into the monitor. Both the DVD and the monitor should be powered off while you connect the cables.
Start up your DVD player and see if the monitor displays the picture correctly. If the picture is scrambled or the signal is fuzzy, you may need to toggle some of the options on your adaptor, such as analogue/digital options or input/output switches. You can also try a different connection scheme, such as using an S-video-to-DVI connection instead of composite-to-VGA.
Most standard-grade computer monitors are not made to handle multiple inputs, so you will not be able to use your computer while your DVD player is plugged in.
