Can any 240Hz HDTV be converted into a 3D HDTV?
Unfortunately, no. While a 3D LED/LCD HDTV must feature 240Hz in order to reproduce a Full HD 3D picture, standard 2D HDTVs cannot be retrofitted to display 3D content. Further, the same holds true for DLP and plasma panels, even though these are, inherently, many times faster than LED/LCD panels.
