I have installed a Parkland screen with Ken's digital grey goo. Because my first sheet of Parkland plastic was too wavy for a permanent screen, I ordered a second sheet. I had a removable screen made out of the wavy (and unpainted) sheet of Parkland plastic. Now I finally have everything installed properly, and am prepared to do an A-B evaluation of the two screens, to provide guidance on whether Ken's digital grey helps the Parkland material as a screen for a DLP projector. (The wavy screen is predominantly flat, but has a few bulges that can be ignored in comparing one screen to another.)
I am not an A/V professional, far from it. I have no test equipment and no interest in buying any. I would, however, by willing to buy a DVD or two if it would help. (My current collection is very limited, and includes Matrix, Congo, Jurassic Park III, Saving Private Ryan, Traffic and Hamburger Hill.)
Are there procedures you think would be useful to follow, or visual material that you think would be useful to review, in comparing the two screens?
