My concern, and something that I havne't seen put to the test, is a standard family room setup with a standard home theater projector with this type of screen.
My DNP test in a boardroom under flourescent lighting was absolutely TERRIBLE! With a business class 4,500 lumen projector (Sanyo) it was stunning. While a white screen was washed out, the DNP screen maintained contrast and had a ton of pop. But, the home theater projector didn't have the lumen output to produce a watchable image on the white screen, and then on the DNP it was simply drowned out.
This is, once again, where it seems like you have to be part of the 1% to get what you are dreaming of. A really good $10,000+ high lumen, theater oriented, projector with a ton of light output, along with the $3,000+ screen.
Might as well drop $10K on the 90" Sharp!
And if you livie in 92651 and have a home with a nice theater to go with your 4 bedroom home, then you are likely in at least the top 5%! I thought our area was pricey, but I'll take 4K sq. feet for $600K anyday over 1K sq. feet for $750K+!
