Depends what input you Monitor has.
The Wii has 3 methods over here.
- (A/V) Supplied cable (yellow/red/green iirc) that can go Phono and Video in. But usually used with the SCART black that usually comes with it. (but not the same as a scart lead on its own)
- (SVIDEO) like above but SVIDEO plug instead of VIDEO
- (SCART) Straight to SCART lead (RGB) next best setup
- (Component Cable), the best setup and you can run the Wii at it's best quality 60p. Don't cost a lot on ebay either. Red/White/Green/Blue/Red plugs yes two reds
