I will go ahead and admit that I might be trying to do the impossible, but I am not expecting a reference quality image. I'm just wondering if there is anything I can do to improve over what I already have. That being said....
I am wondering if someone could explain the relationships between brightness and constrast to me a little better.
First the physical brightness vs the contrast abilities of a projector. I've heard that Piano chose to go with a lower light output (450 lumens) to get a better contrast ratio compared to most other projectors of that class (most have 1000 lumens or so). Then there is screen gain. The higher the gain, the whiter the screen, the brighter the image looks, but the lower your contrast? So it seems to me that you would want a high gain screen for a low light projector?
I guess my biggest misunderstanding is this. I have my Piano farther from the white wall I am using as a screen than I should and am projecting an image about 50% bigger than recommended. I then set the picture controls to those as mentioned in a review in Stereophile (I think). I was thinking that this would end up giving me perhaps a darker picture but I ended up with a washed out, but pretty bright image. I really wouldn't mind the image that I get if the blacks weren't so bright gray. How high can I set the contrast control? What does boosting the contrast compromise?
I have to take down the projector sometime in the near future to send it back to Plus to get rid of a dead pixel (they are being really cool about that ) so I will try setting it up at least temporarily for the the recommended 80" screen size and see what I can do about this picture.
