No, a straight cable won't work. There are two kinds of component video, YPrPb and RGB. Consumer electronics devices (e.g. DVD players) generally use YPrPb, and analog computer monitors use RGB. I need a box that will translate the signal from one "flavor" of component to the other.
I know a good supplier supplying VGA to Ypbpr converter.
And i bought one piece from them before. Now it works well.
You can get in touch with them.

I can personally confirm that these cables do NOT work.
I stupidly assumed I could plug in my Wii component cables and connect it to my HD monitor but a converter box is necessary.
