Hey Drags is the Theater owner Greek? Nicodemus sounds Greek.

quite possibly, he actually looks a little like you. It would be pretty far back though, more than 2 or 3 gen's I'm sure.
So while were on this topic of rooms, screens, and such. What would you guys recommend for this room. Be nice now, there's a WAF to consider. Something that would work with the maple floors but still be Videophile friendly. I know the White ceiling is a disaster but what would you do within the constraints of this space Color wise? I'm thinking a really Dark Blue on the walls would work well with the Gold floors. Then a Black ceiling and screen wall would be perfect but what color other than Black would you recommend on the ceiling if the ole lady really digs her heels in??

Drags, what you can do there to help out with with light reflection is to add a curtain going across the entire room about 3 feet in front of the scree. with a valance that runs across the top just low enough to not interfere with the Image. Now on that part of the ceiling you paint it with a Black flat paint or get some flat black velveteen type cloth. Also you can paint the hidden part of the walls black too. When the curtains are closed it hides the screen, speakers, sub etc. If that Support Pole is close enough you can make that the point where the curtain begins, to me it looks about 3-4 feet from the screen wall. You could even make a riser on the floor in that area and cover it with Darkblue, black or Maroon carpet. Just a 6 inch riser would be cool and easy to build so it can be removed later and not hurt the hardwood. Use foundation foam under the frameing.

Oh and BTW, that's another thing I saw. the HP fabric was much thicker than any of the other samples we had. That stuff will NOT get all wavy on you like a typical roll-up screen.

Even if it did, I doubt you'd notice it. Waviness is a problem on angular-reflective surfaces, because the light gets reflected in different directions so you have big brightness variations. But with a retro like HP, it doesn't matter. Waves should be just about invisible.

One more thing, I'm guessing a pro-calibration in that room as it is now would be a waste of money no?
I can just see the guy walk in, big frown crosses his face, followed by a lecture/scolding on proper color temperature and contrast ratio capability of a system which the room is a big part of, etc. Followed by a grumbling "I can't believe i'm being paid to do this" attitude Laughing

ok, here's an example of a " not-perfect but as good as can be under the circumstances" paint. The walls are a darker shade of green and a little lighter on the ceiling but this is a living room in the middle of the house so Black was not an option without Divorce Laughing
The biggest problem with this room is there are 2 doorways in the back which open to a kitchen and den so there is almost always light spilling onto the screen. Drove me crazy as it kept washing out the screen

Drags,
I didn't mean to take this thread off tangent. It is a nice looking HT.

As for the High Power, if it works for you then great. FYI, Jeff Meier tested a bunch of screen materials.

Thanks for posting Spanky. So the measured gain for HP is <1 off axis, which I assume was tested using recent HP material. Sorta confirms my own observations with the older screen. I'll report back when I receive my new samples from Da-lite.

yeah thanks. Look at the numbers though. HP = on axis gain 1.82, off axis .96. So even in the "wrong" seating position your still getting what a normal matte-white screen is giving you. That's 18 degree's off to the side and 6 degree's down. What I saw in the Nicodemus theater room is no matter where I moved to it was brighter than matte white, so in this particular case I think his off-axis might have been more severe than the typical viewing positions we had.
at any rate, as you noted "whatever works for you" is really the right answer. Screen choices are like speakers choices and ice cream flavors. There's no right or wrong, it's whatever the person paying the bills decides they like.
The one I find interesting is the silver 5D, "not one I would recommend for home theater use because of the image quality degradation from reflective elements". AMOF, out of the 3 screens listed at max possible gain of around 2.0 the HP was the only one he didn't outright reject and gave it a "best in class".

Just be careful to get a full flat for the ceiling / screen wall with no shine and you'll be Golden.

Disney mouse ear black buddy is the color of the ceiling. Blacker than a coal miners bottom.

The darker the better for sure. I keep mine all fairly dark, with the ceiling and side walls flat black.

P.S. I like your sig... you have good taste in beer! If you make your own (or are interested in doing so), check out *my* sig!

I'm going to throw out a counterpoint for the sake of full understanding. Flat black looks awesome right up until the moment somebody even thinks of touching it. At that point it gets touched, it's IMPOSSIBLE to clean. If you want the mark off, you may as well repaint. Seriously. Something as innocent as a tall guy stretching and dragging a knuckle across or something... You will NOT clean the mark off. My ceiling is a very muted medium-to-dark blue. It's pretty flat (but not extremely flat), and it still shows marks.

Your room does not have to be a black cave to be a good-looking room that doesn't throw a lot of light back on the screen.

I used Ralph Lauren Suede type paint for the walls, it leaves look of brushed suede. Some don't like the uneven look but I like it.
I have a drooped ceiling and use USG Panels that have a really rough texture and made in Black. They can even be used over a dry walled ceiling or with out the track. In one area i couldn't use the rail system so I just screwed it into the wood frame. They but right up to each other and are soooo black you can not even tell. I even use them on the half walls between my seating sections. Helps absorb reflections of sound right behind your ears.

Thanks buddy!! I deal with beer every night in my night job, having said that I know a lot about brewing and beers. I have started to make my own spir*ts. Next on tap is gonna be Sierra Nevadas Northern Hemisphere IPA.

That's what I do, every time I take the cover off the Ampro I hit the ceiling with it and leave a white mark. I just dab it with the paint brush and it blends right in.

Samples of the latest HP material just arrived. Dalite were kind enough to UPS 2 sections which will help with the evaluation. At first glance the 12 yo HP material I have in my fixed screen looks different to the new samples. There is a lot more texture in the new stuff. I also think its a little thinner but not as thin as some other samples I have of their screen material. Wrinkles should not be a problem.

I wonder if this texture is why you're seeing better performance off axis. Can't wait to run some tests this evening.

could very well be. If the material is purely retro reflective then texture would increase the number angles it would be reflected back to. I've never seen the old stuff, new stuff always looked good to me. Not perfect but pretty good. Let us know what you find.
BTW as the review noted the screen overall is not entirely color neutral. It tends to deliver a cooler looking "blue shift" which might be objectionable to people who prefer either a warmer or more neutral pallet.
