Hi everyone.
Does anyone know anything about spherical aberration. I've heard that some projectors don't suffer from it, vivitek is a good example I think.
But now I've bought an acer and I'm really satisfied and different areas in the plate have different brightness.
Is it possible that I modify its lens with a better one from different companies like canon? Have anyone done it before? I've although seen some machine have a motorized lens than can be adjusted and they use a lux meter to adjust it perfectly.
Vivitek vs acer
