I have SLI 570GTX thus supporting 3D Vision. I have been looking at 120Hz monitors but first I want to know if I were to plug my LG TV that has a 240Hz refresh rate to my PC and switch on Stereoscopic, what would I need? Such as active or passive glasses? Would this work at all? I can't seem to find the info needed to go through with purchasing the glasses at first, and then eventually look at my monitor options.
