All these 'Put a lens in front of a TV' schemes have one tremendous failing, they lose a heck of a lot of light. In order to keep the light losses low, the lens would have to be much larger than the TV screen size and that's just not practical.
A large plastic Fresnel lens might be cost effective. I suppose Edmund Scientific might have a usable one.
