yeah can you believe it, people are still installing these "obsolete" things.Rolling Eyes This was a little after-work project I guided and helped a friend through. Got to see it last night in it's full Super Bowl glory and I have to say the room has met my highest expectations AFA , sound quality, picture quality, and the overall feel and function is concerned. There's a lot of "wish I had done that to my HT" like the super dark carpet and walls, the built in equipment rack, etc. but it was cool to apply those things I learned to a fresh build. Total cost was right around $7.5K including construction, paint,carpet,electrical, dry-wall, doors, and even the equipment.
PJ is a Runco 980 (late model 6PGX, PS3 - MUX HD, Marantz SR5006, and full Quad L series speakers (5 channel) in Piano Black Laquer. Screen is a Dalite high Power 52" x 92 inches wide. Equipment rack is built into the front/side wall. in the back is a washer dryer/closet on the left and a fridge/Kegerator closet on the right. As always, the pictures don't do it justice but you can get a rough idea

What a shame. The benefits of the HighPower would be completely lost in that setup with those viewing angles.

that's absolute BS. I have draper M1300 at the exact same size which measures in at 1.25 actual gain. The HP is much brighter. He had the wall sconces and even the cans lit at one point and the image still was still vibrant and punchy. didn't matter if you were seated or standing.
My screen goes dull with anything more than a dim glow from the lights.
Seems like everything on this forum is like " that's totally WRONG. unless the PJ is on the floor and everyone is sitting in a perfect viewing cone it's WRONG.
What total bull****. I've installed a number of HT's for people and I know what the majority of the screen choices are. The HP looks fantastic and the only time it doesn't is if you have light spilling in from directly behind it or the room/carpet is light colored.
Not only that I took 4 swatches over there, matte white, cinevision, m1300, and high power. Guess which one the guy paying the bills picked? Confused

I've never seen an HP with a ceiling-mounted CRT. (A guy nearby has a HP and a G70 but the G70 sits in the front row.) It may look really good, and it will *definitely* be fabulous at rejecting off-center light from sconces &etc. It would be a great screen for watching in a partially-lit room, as long as the light source wasn't behind you.

Once I got a sample of HP and tacked it up on my screen next to a piece of white printer paper. Standing up, the HP was practically radioactive. TONS of brightness, so punchy it would practically punch you out! I would have turned the contrast WAY down on that puppy and it would have still been awesome.

But when I sat down, it died. The HP was actually slightly dimmer than the white paper. My eyes were too far from the light source, and the HP sends most of its light right back to the light source. There's not really a "perfect viewing cone" but the farther your eyes are from the lenses, the dimmer the image will be.

It may still give a good picture, though. HP does NOT hotspot at all, almost the opposite. So you'd have a much more even and uniform brightness level across the screen than you would with anything other than *maybe* a 1.0 gain screen. As long as you can get enough brightness at your viewing location, it's probably about the best screen you can get.

Are you suggesting that if someone has a lot of money, he should get a digital? Confused

Not at all, If you have lots of money a professional calibrated Rear Projector Blend is what I would do. Using a Blue Ocean Rear Projection Screen and the latest VDC Marquee 9572LC's Very Happy Can you lend me 100,000 for the project? Wink

Thank you. I still have a 110" Dalite HP screen (couldn't bring myself to sell it because its that good) and installed it after moving the pj from the floor to the ceiling in the new HT room. In my experience the main benefit of increased gain was lost. The HP is retro-reflective and the gain performance drops off dramatically as the viewing angle increases. My screen is 10 years old so maybe they changed the formulation to offer greater off access performance. All I know is that my Stewart 130 material is brighter then the HP from my seating position.

I'm using a $20 piece of plastic for my screen that I purchased at the local hardware store, dont know what gain it is, but it doesnt look bad at all to me. It would probably look horrid to a lot of you on here, so I can only imagine how a nice actual screen would look.

Draganm, looks awesome Thumbs Up I like the wall color and carpet a lot Very Happy

That's exactly what I though when I read Gary's post. We tacked up all our samples on what is now the center of the screen. I had the owner both sitting and standing and moving left to right while I stood up and used a mag-light shooting from the ceiling to simulate the projector /light source. The HP just jumped off the wall at any angle, you can see it above pics how bright the screen is with the projector off. Was it the same brightness from any angle, no it was not, but neither I nor the other guys there saw what you guys are describing , a massive drop-off. I even explained to them the entire directionality/ Stop sign technology but the HP beat the crap out of the others in light output.

Man do yourself a favor, even if you have ot eat Top Romen for a month a $300. roll up like the one in the pic is SO worth it .
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.

thanks guys, owner chose the room colors. I told him any color ASA it's dark. I was surprised and pleased when he went black ceiling and screen wall. Most newby's are clueless about how important room color is.

Now that is interesting. I think I'm going to get some fresh samples just to compare side by side with my 10 yo HP screen. I would love to go back to a HP screen setup

Sample ordered. Website says the material has a 30 degree viewing angle, but not how much gain drops at the extremes. I can't remember the specs for the 10 yo HP material I have. This will be interesting.
