PS2 to PC monitor

My 24" monitor has VGA and DVI inputs, what is best for PS2? I could use my plasma with it instead but I think blowing up PS2 upto 50" might not so good.

You need to buy a few parts before that works. I did some research on this a few years ago - the problem is that the PS2's video output is interlaced, you'll have to buy some adapters to get it to work on a VGA connector. There are some expensive ($40 range, but maybe they are less expensive now) devices that will do all the work, or you can google around and scrounge around some parts to put everything together yourself.

That said, I never did pursue hooking my PS2 up to my computer monitor.

If you use a component (blue, red, green) cable instead of the composite (that comes with the PS2), the picture quality is a lot better, especially if the game allows you to use progressive scan.
