In my situation, with the text ghosting, the issue is confusing because any image other than text is clear as a bell.
At times, my screen looks as if it made up of horizontal strips - the way the image is shown.
My screen (accoustically transparent) drops down in front of a white pine hutch which is part of a built in bookcase / cabinet. Occassionally I've been able to see a pin hole bright spot reflected back through the screen, and have taken care to remove anything shiny from behind the screen.
Again, other than the issues with the white text, I'm 100% pleased with the picture . . . .
