Update on painted wall screen.
Well after drying for 24 hours, the screen is actually better!
I can't see the 'dirty screen' except on really light images (like entire panning skies etc.), even then it isn't as bad as yesterday.
We used it all day with the curtains open and had no trouble watching sports, news etc.
I love watching baseball on 118" from 11' away! My wife likes it smaller 95", as her eyes get tired.
We watched a movie last night full size and had no trouble with eye fatigue, as it was the wider aspect blu-ray, so the image was shorter than the 16:9
Thanks all again,
