I am looking around for some information on what it takes to convert over to a curved screen. Do you need a new projector that requires a special lens? I know a while back there was still no projector that could display an image on a curved screen unless you bought 3 projectors with special lensing. All i have right now is an HD33 for now that i use on a 112" Carada screen.

Sorry for the noob question.



Thanks

A curved screen is used when using an anamorphic lens. The curved screen helps to eliminate the pin-cushion effect caused by the lens. A-lenses are used to stretch a 16:9 image to 2.35 and eliminate the black bars. Which also gains brightness back and not waste the light output in the top and bottom black bars. No reason for a curved screen unless you use a lens. he lenses cos more than mos common projectors - start at about $3k, but there are a few that are less expensive.

Are you referring to the old CRT projectors? They would had thee tubes - red, green and blue and projected on to a torroidal curved screen ('80s). Unfortunatly CRT's have gone the waay of the dinasour as digitals have now caught up and may have even surpassed them in some respects.
