wii can't support vga port,so if you want to play it with LCD or CRT,must use vga box or tv box,but wii only support 480P.
i suggest N6 or HD12,these are viewsonic product,but may be too expensive for you.
this is the product website N6(http://www.viewsonic.com/support/ac...ionn6/index.htm)
HD12(http://www.viewsonic.com/support/ac...nextvisionhd12/)
