I've read a lot about dustblobs on the forum and how they can mess up the optical output of a pj. My question is- What about airborn dust between pj and screen? How much effect does airborne dust in the viewing room have on picture quality? I ask because a friend just got an X1 and has not been happy with picture quality, whereas I couldn't be happier with mine. The one thing he's told me is that his basement setup has a lot of airborne dust. Could this be the problem?
