I agree about their projection. In all my decades of visiting the Uptown, I never saw any dust or hair projected on the screen, which amazed me given how large the image was.An oddity for the Uptown. Their projection was as perfect as possible.
Re the non-strip screen, it had a major cross-illumination problem. They should have replaced the strips!
As for the cross-illumination problem, maybe I never noticed it because I usually sat dead center in the orchestra.
