I just got my Panny 8000. I can currently project a 128" 2.35 screen image on my wall. If I zoom all the way out I can almost get a 136" 2.35 screen. I am trying to decide if I should move my projector back another foot so I can project onto a 136" screen. I am concerned about losing brightness by backing the projector back and/or zooming out near the extreme of the projector's capabilities. Right now if I stay where I am and use the 128" it is close to the end range of zoom. Am I overthinking this? Thx in advance.
16 fl down to 14 fl difference it looks like, on a 1.3 gain screen. That looks a little low to me, but if your in a cave and a higher gain screen, (>1.4) you might be ok, considering some lamp dimming over time. If you can move it around, w/o much trouble and put it back closer, then try and see if you like it further back, since your not using a screen atm.
I should have included that I don't have my screen picked out yet. I am looking at carada. I have samples of grey, classic white and brilliant white. I am currently running my projector in eco mode and I am more than satisfied with the brightness on classic white. I really do love the blacks on the grey screen. I would assume that I am around 14 to 14 1/2 feet currently from my wall and my room has controlled lighting.
My biggest question is how much will backing the projector up vs not having to zoom out as much affect my picture. At the most I would assume I would go to 16' to achieve 136" 2.35 projection.
