There are a few advantages to the shorter throw curved screen set up with lens. The shorter throw does give you added brightness, the curved screen reflects less light on the side walls and it also directs more light back to the viewer. The curved screen is pretty cool looking also, but I would not recommend a curved screen just for the coolness factor, because of the drawbacks listed in the posts above. The curved screen choice really comes down to screen size wanted and throw distance available for use. In other words, I would not go with a curved screen, unless the situation required it, because there is added cost involved. In my case, I could not have gotten the screen size I wanted in my room. Did not have enough throw to do the zoom method for my 9' wide screen, but using a lens I had plenty of throw. It did require me to use a curved screen. If considering a lens, then one of the most important aspects that I have found is, what you are going to use to preform the vertical stretch. From what I have seen, many projectors when preforming the vertical stretch, soften the image when used with a lens. A good video processor preforming the stretch, keeps the image sharp. This aspect is often times overlooked by lens buyers and they end up saying the lens softened the image, when the lens really had nothing to do with the problem.
