Hi Guys, im building a new dedicated home theatre and was browsing through the threads and was wondering why majority people with a dedicated home theatre will not go for 150" screen? some will go 120" and some 138" etc. Is it because people are worried about the picture being to dim? Im planning to have a 150" 2.35:1 screen by Screen Innovation zero edge slate 1.2. Viewing distance for front row about 15' and second row about 18'. throw distance 17'-18'. Projector will be Sony VPL-VW550ES 1800 lumens claimed. Movies will in 4K and upscaled 4k, except for 3D. Will be using low lamp for all views. My question is would it be to dim for a 150" 2.35:1?
