I always use max throw. At first I didn't tho. I read how max zoom hurts the image. I was using dual screens, a SI Gamma 4K 1.1 gain that was 100in and a 120in HP 2.4 screen. I just use the HP screen for 3D. I was using a RS55, so I wanted to get the best contrast possible with a good unity screen. I kept the iris down to -11 and it looked great, contrast was around 40,000:1. I was happy. Until I found myself watching Star Wars Episode 1. I wanted to try out the 2D-3D, it didn't impress me at all, so I kept the HP screen down for a little. It was bright, so I put the lamp on low and closed the iris to -15. It was bigger, brighter, with better contrast at over 50,000:1. Just having 15ftL with 50K:1 contrast is really good, changed my mind on what people say. So, I sold my SI screen.
I had the RS48/X55 for a couple of months. I got 42k:1 with 15ftL with max zoom on the HP screen. Some will argue that less contrast on a unity screen will look better, but with my experience, thats not true. Even the Sony VPL-1000ES owners will let you know that the JVC will have better contrast, with the Sony being around 20K:1. I'm not saying the JVC is better but transitioning from dark scenes to bright scenes shows well on the JVC. Even when you use max zoom with the iris open, you will get over 24K:1 on the JVC, which is better than most.
