I've been very satisfied with the Dell 2007wfp... I know Dell makes a cheaper 20 incher, but this has a higher quality panel, plus lots of inputs (I don't know the outputs of the Wii, but this could be easily verified). If you're willing to throw around a little more money, look at Dell's 24 inch. Dell has a great mix of quality screens with very low prices. Hard to go wrong, I'd say. And mine has been a champ with my MacBook Pro.
