i currently have an LCD television with a 60 hz refresh rate (i think. it's an emerson 32" that i got for $400) and i cannot play the NES on it because of lag. either the tv isnt made to process the analog (or component cables with the wii and virtual console games) or the refresh rate is garbage. i am in the market for a new tv. how fast is fast enough so i can play an NES game with it?
