    As CRT projectors age and the tubes became not as bright as they once were is it possible to greatly reduce the projected image size and increase brightness. I have a Sony 1040QM currently projecting a 100" image but it's not what it once was, if i make my image significantly smaller by moving the projector closer to the screen (and obviously setting it up again) will the image get brighter or am i barking up the wrong tree.

    You're not barking up the wrong tree. The same projector firing onto a smaller screen will produce a brighter more punchy image. So I think it's worth trying if you want to squeeze a little more life out of your projector.

    Inverse square law.
    If I recall half the projected distance and you will get 4 time the amount of light

    Hi,

    While the Sony 10xx projectors will go up to 100-250in, they are probably at their best with a 72in (4:3) set up. Remember that you'll have to adjust the lens 'spacer' rings and the tube spacers from 100 to 72in.
