I just mount ceiled my Sanyo Z3 from a distance of 4 metres (= 13 feet) away from my wall. I'm sitting 3 metres (= 10 feet) away from the wall. I was going up and down with the "zoom lever" (I think it's called like that) so you make the projected picture bigger and smaller.. the smallest I could go is 85" There's a rule about the distance you need to sit away from the screen + the measures of your screen, right? (diagonal: 85") can someone tell me that rule? I think it was something with 1.5/2 I was a bit "shocked" I couldn't get the picture smaller than 85".. how can I get it smaller (IF the rule doesn't agree with me) ? Putting the Projector closer to the screen I guess.. but that isn't a practical solution I was browsing through the menu and I found "Screen Size Adjustment": Full, Full through, Zoom, Caption in 1, Caption in 2, Normal, Normal through, Natural wide 1, Natural wide 2 with Full through and Normal through I can get my screen smaller, but I don't know..when I use those the PJ projects black around the picture... ? A lose in quality? PS: 85" screens, are they easily to buy? I'd like to project my image totally on a screen, without white empy spaces.
