Actually it depends on the type of monitor you have. Some monitors, mostely widescreen, have composite in's, component in's, or s-video in's. If your monitor only has a vga out, it is possible to purchase a pass through adapter box that converts it to composite or component; this is what projectors use. They are a little pricy and tricky to find but it is possible (try NewEgg); although I'm not sure how that would affect the Wii in terms of gameplay. Unless you are just wanting to use the monitor for the hi-def component aspect, I'd just stick with a normal tv.
