Used to use a VGA box for playing my Wii on a PC monitor, but it blurred the picture and would only work in 50hz. This cable produces a crystal clear image, runs at 480p and 60hz.
I've read a few comments about the image blacking out for a second once in a while and I've come across the problem, but only when I'm playing imported NTSC games. My PAL games all work perfectly.
I tested the cable on a PS3 too, it took a while to get it set up, but once I did, it ran perfectly. Well worth the price.
