Even though I am here daily I missed this thread from 6 months ago and yet this Dalite High power screen is the most impressive thing I've seen since my moome card and HD player. Also, you can extend the life of your tubes by 20 to 30% , no joke

I can attest to the awesomeness of the High Power screen. If you have the right setup nothing else comes close IMO.

I wouldn't get that screen unless your plan is to pull the material and put it on a frame. The model B uses a small roller and will make the material wavy. The model C is much better. Mine was about $450 shipped for a 96" wide.

All of you have floor mounted projectors?

Dragan, you didn't see this on your projector in your HT, did you? If not, definitely get a sample of the fabric and test it before you buy. I put a 12" square swatch of High Power on my cheapo BOC screen and, standing up, it was like a beacon. SOOOO much brighter, so much more pop! Could have dialed the contrast WAAAAY down and still had a much more vibrant image.
Then I sat down, as I would be when watching, and -- the HP lost ALL its pop and presence. I don't remember exactly but it was either just about the same brightness as the BOC, or even a bit dimmer.
HP is a retro-reflective screen, meaning the light bounces back to the light source just like a stop sign bounces light back to your headlights. Your eyes have to be close to the light source for HP to work well. Stand up so your eyes are close to the ceiling-mounted pj, and it's awesome. Sit down and you increase the lens-to-eye distance, and you cut the effective gain by 2x or more.
Mark Sprenger up in Windsor has an HP, but his G70 is floor-mounted. In the prime viewing chairs, your eyes are only about 2' from the lenses. HP works fabulously in a setup like that, other than the color shift. But not for ceiling mounts.
HP does have some fabulous advantages. Its uniformity is unmatched by any normal angular-reflective screen. It doesn't hotspot AT ALL -- the optics don't work that way. And Zebu, waves should not be an issue with HP, since the angle that the light hits the screen is irrelevant. The two big drawbacks of HP are the eye-to-PJ distance issue, and the color shifting with CRTs.
BTW I'd be pretty surprised if you actually saw a color shift between L & R sides of the screen. When YOU move, then the whole screen changes color -- warm when you're off to one side, cool on the other. But from any given viewing position, the color uniformity should be very good across the screen -- not perfectly calibrated, but uniform.

No, my G70 is mounted about 1' above my head. This works out great for me because the roof is pitched where the G70 is hanging so it doesn't look too out of place. This mount also helps with focus as the angle of projection is close to 0, this minimizes my need for flapping.

The only issue I have with the waves are the way they look on the screen, you never see them when the movie is playing and the lights are off but they bug me when the screen is down and rippled. No big deal though it is only cosmetic.
I agree with everything you wrote, very good summary of the HP material

well that's dam good advice, I need to do that before I sell my $1K Onyx and then spend the rest of the year regretting it.

you know that's wierd but at Gerry's place in Littleton I didn't see this? First I sat in front row, PJ lenses approximately 7 feet overhead and I was like WOW. then I sat on the elevated Dias in back and I was still WOW.

I didn't see a traditional color shift, the entire screen was warmer when standing to the right and cooler to the left but uniform otherwise. It was a non-issue for me

Well that's a gruesome little detail isn't it ? good to know, thanks!
I guess I need to contact Dalite for a sample. Any other material I should ask for while i'm at it besides traditional 1.3 gain White?

The other bonus is that it happens to be one of the cheapest screen materials Da-Lite sells.
I'm considering HP too, but my ceiling-mounted PJ is just high enough that most of the punch is gone, though it's still a tad brighter than my temporary BOC. So even though most of the benefit is gone for me, it's cheaper than the standard unity gain Da-Mat, so I might pick it up anyway. The problem is that my side couch has seats with fairly pronounced off-axis angles, and the image is darker there. Not sure how much I want to care about that since I'll be in the good seats the majority of the time.

the demo I saw was in a fairly narrow room so couldn't check off axis. It's like my room though, seating is 3 + 3 , everyone is within 30 degree's.
Anyone know how get an HP sample swatch. I looked over the Dalite web-site and if they offer it it is NOT obvious.

Just email them and ask for a sample. Make sure you ask for the larger size, they sent me the entire selection of materials.

I had e-mailed them this morning requesting the 4 samples and received a reply back in about 15 minutes that they would be in the mail tomorrow.

After reading the thread I am giving some thought to buying a Model B 52x92 and cutting the cloth out and installing it on my DYI black out frame. My PJ sets about 2 feet over my head when setting in the sweet spot, Has anybody witnessed this type of set up?
TIA
