Many LCD screens have connectors to connect up to a DVI-D plug, which is basically a digital video connection. LCD screens operate digitally, which gives them a much clearer image than a CRT. CRT monitors are analog, meaning your video card has to convert it’s digital signal into something the monitor can understand. In this process, a little quality is lost. If your video card only has a standard VGA-out connector, then you have to use an adapter to connect your LCD screen to it. It might be worth your effort, though, to eventually switch over to a digital video card, or one with a DVI-D output. This way you get the most from your LCD monitor.
