Maybe you can get a gray screen if you worry about contrast. With the lumen this PJ going to give you, a gray screen with 0.8 will still be quite good. Again, without knowing your room and light condition, I am just making a guess here.
I am not guessing, and the images I posted take the "guesswork" even further out of the picture.
Considering the essential brightness of this PJ, that factor...and that alone is what keeps it from achieving far deeper levels of Black. Reducing the intensity of light output at the source is NOT the answer, rather one must attenuate (...as selectively as possible...) the darker shades of Gray Scale.
The darker wavelengths of light are less intense, imbued with less energy, so they attenuate more readily than more energetic light. A simple Gray screen of .85 gain would help, but there would be some degree of undesirable attenuation of colors and whites along with the deeper shades of Gray.
However, a Screen with modest "positive" gain and a N.8 Gray shade will work to best advantage, deepening perceived Black levels, while maintaining as much reflective output of the lighter elements as can possibly be done.
That is exactly what you see being accomplished in my previous images. With this particular PJ, it's a solution that is ideally suited to improving a already excellent viewing experience.
Someday we will have a $1000.00 SXRD / Lycos unit with 2500 lumens AND 1,000,000:1 "Native" Contrast. Then....virtually any smooth white surface will suffice. Until then however, PJs of the CG181D's ilk will perform well enough when matched to the correct screen to satisfy anyone who is contemplating a purchase within the LG's price point.
