While awaiting delivery of my Stewart Grayhawk, I spent Sunday running some tests on my G11U projecting on finished drywall. Instead of plain white I used a product called Martin-Senour Bright Lights Wall Paint and the picture was excellent. This product is designed to be more reflective and produce brighter room. I recommend this as an option to those of us that have multi purpose rooms or are "screen challenged" for FPTV. Anyone need any further info - just ask. Thought I'd pass this along.
