RS-10 2.4:1 screen? - Blu-ray Forum

squirrel101 · 02-21-2009, 04:33 AM

Does it hurt picture quality to just place the projector @ a throw distance to fill the screen when not using an anamorphic lens? If so i would like to know so i can build a curved screen and add a lens probably HTB unless the prismasonic is affordible. I plan on placing the pj @ the throw distance to achieve the scope screen size and then zoom in for 16:9 material

,thank you.

No-- it won't hurt picture quality. In fact, some people feel that is the best way to do CIH as it avoids any image degradation from introducing another lens into the light path. You do lose light output (~20%) and the advantage of using your entire imaging panel to reproduce the image. It is also a bit more inconvenient to have to zoom & adjust image height every time you change AR's as opposed to just sliding a lens in and out of the light path, unless you have a servo controlled lens with memory functions. Zooming should be fine as long as your throw distance/zoom range supports it.
