I suppose it's good to know I'm not just crazy; they are difficult to find.
I'm an installation artist and we got an acceptable image last weekend from my Sharp XR-30X DLP projector rated at 2300 lumens. The unit was 6 feet from the screen, displayed outside at night during a full moon. Streetlights were not an issue.
I was hoping to use something like the Optoma ML550 or 750 under similar conditions, positioned closer to the screen and displaying a smaller image. I would love to try before I buy.
Perhaps I should purchase from a vendor with a liberal return policy? Any thoughts would be appreciated.
