Out of the 8 seats in my setup using the 6" square Dalite sent me months back I only have one seat where the picture looks as bright or possibly brighter. In the remaining 7 seats that I have the brightness difference is quite noticeable.

Thats the down side of having so much gain. But in its sweet spot it smokes all the expensive wide angle screens in their sweet spot. They become down right boring in comparison and less money to boot!
But its another matter entirely if you want the whole family or a group of friends to get the same picture equally. In that case the wide cone is a benefit.
Pick your poison!

If I didn't have the 2.8 gain I'd get the 2.4 in a heartbeat. I shoulda woulda coulda bought the bigger screen some time back when I had the chance. I'll probably wait and see how bright the RS45 is. If it's very bright then the 2.4 gain might work.

My 144x72 HP2.4 is quite bright enough for me with a RS20 with ~ 2000 hrs on the lamp. (In 16x9 config is is 128x72,)

Having experimented with the HP 2.4 samples, the dropoff seems to be more noticeable with smaller samples. I first got a 6" sample and then a 12" sample, and now I have a 122x66" HP screen now. The dropoff was less noticeable with each size increase.

Life is good.

I will probably wait until I get the RS45 and see how much brighter it is over my RS2 clone. I didn't think I'd be saying this but I am interested in 3D and the brightness matters so I'll see how that goes as well. If I can spare a little then I may go for the 2.4.

I was thinking about a calling and getting a 12" sample as the 6" sample really isn't enough. Now if only they would give my a 119" sample.

Think about it this way.
If you do not have the projector in the optimum place or some of your seating is out of the viewing cone, you will get the same image as you do with a white screen that has a gain of 1.
What's to loose? You sit in the captain's seat which should be directly under the projector shooting just over your head, unless you give it up for an honored guest! You will always have a great picture and the seats next to you will also have a great picture. No one that I know of has ever complained about the full size screen looking darker on one side that then other from any seat. In fact the opposite is true, they say it has a very uniform brightness. Unfortunately I have a very small screen so my personal experience is not very useful when talking about a very large screen. You should get the bigger samples as you say and see if that helps any in your decision.

I am really not looking forward to the day i want to upgrade my 2.35:1 highpower to something bigger.

I have a 94inch 16:9 in behind, and a second one just about the same size with masking on top and bottom da-lite did for me that drops down in front.

I had to go with this because my projector had no zoom method so calculations had to be done to work out the appropriate size.

Now looking at projectors I had hoped to buy one with a zoom method, so i could get a bigger picture for 2:35 and 2:40 movies and just zoom in manually, but now the screens wont match. They will have different gain. If i want to go bigger i would have the masked screen with less gain and for 16:9 content higher gain and brighter picture.

Or I buy a new 16:9 as well in the 2.4 but that would put a hole in my pocket, dalite charges crazy prices for the electric screens.

Hi,
I'm running power in the attic this weekend for an electric hipower screen, and was wondering which side of the screen Dalite puts the power and 12v trigger. I called VA and PP and both are closed. The only pic I can find is a Designer Cinema Electrol and it's power is on the left, so this is how I have it for now. The Sheetrock guys come Tues so someone pls let me know if I need power on the other side. Thanks.

Go to the dalite website, choose the model screen you have and on the right and side of the page you will see pdf files including installation .. one of those pdfs will show you what you need to know

I think I may have a problem with my screen.

I just took delivery on a Cinema Contour screen and I'm assembling the frame now. However, none of the screw holes are matching up properly.

I know that the instructions say that they won't line up until all fasteners are attached, but the frame is together all the way and they're still mismatched.

Any ideas? Is there something I'm missing?

I think you're supposed to match up the holes and put in the screws (not tight) and then when all the screws are in you can tighten them. Then look at the frame and it should look fine.

Also note that the 4 pieces are labeled 'top', 'bottom', 'left', and 'right', and the holds only line up correctly if you have these correctly positioned. (I think I once starting putting one of my HP's together and had the top and bottom switched.)

Yeah, you're right. I tried again last night and the screws went in far enough. I did this for all four corners and then tightened them. I just assumed that they would all line up after the screen was pieced together.

But all is fine now and the screen is fully assembled.

Sorry... I have another 'issue'.

I've noticed during scenes of solid color--like a shot of the sky, or many scenes in an animated movie, where larges areas of solid color are prevalent--I can see the screen's texture. It's very distracting. Has anyone else noticed this sort of thing?

I just got my new Cinema Contour with High Power put together and on the wall. Wow, those snaps are a bitch... Anyway, I noticed a part of the screen that isn't stretched out like the rest - it's like there's too much fabric and it makes a bubble. I was just wondering if this is normal/acceptable? Will it get worse over time since it's not properly stretched? It doesn't appear to be too noticeable from the front, but I haven't yet set up my projector.

Any opinions?

Hopefully my attachment works. It's not the best picture since it's from an iPhone, but it'll get the point across.

That's not normal. I don't recall, but I think there's a recommended sequence to snap the screen in to avoid puckering. Perhaps someone else here knows or you can call Da Lite. Maybe try snapping the center points and then working out to the corners, doing opposing sides as you go...

I wouldn't leave it like that.

All the snaps are snapped - you think undoing them would make a difference? You'd think that once it's completely snapped it'd be tight regardless of which order they were used.

The directions said to start with the 4 corners (which I did) and then do the rest. Hmmm... Anyone else have suggestions as to how I can remedy this? Or do I have a defective screen?

If you're following the directions, I would contact your reseller or DaLite - that appears substantial enough that it would effect image quality. If it doesn't, then its up to you if it bothers you or not...

To update, Mike at AVS was very helpful. DaLite sent a replacement out overnight shipping and the new screen is tight as a drum.

The more I've been watching the screen, I've been noticing some darker horizontal lines that show up during bright scenes. It's especially evident when there's a camera pan or movement on a bright scene. The most noticeable one is about a third of the way down the screen - it spans from left-right but the left side is more pronounced. There are others toward the bottom of the screen as well, but those aren't as noticeable.

Could there just be lines of dirt on my screen? I'm nervous to try and clean the screen because I worry about causing streaking or other more annoying issues. Plus, why would a new screen from the factory come dirty?

I'm getting frustrated with these issues I've been having with the HP. DaLite was really helpful with the first problem, but at this point I'm hesitant to complain again as I may just be seen as a really picky customer... Plus, given my first experience, I'm nervous that any replacement with have other more glaring issues. I've tried to take pictures of what I'm seeing, but it wasn't working out so well with my cellphone camera.

OK, I took a picture with a normal camera+flash in a dark room, projector off. Hopefully this picture can better describe what I'm seeing (at least in the most pronounced location). Again, it's more noticeable with movement on the screen.

NNate,

I have one of those on my HP Model C pull-down. It sits a bit lower than yours.

This was after I went though 4 (count em, 4) other HP screens from Da-Lite. One was the new (2.4) and others had a series of tightly aligned vertical stripes. I settled on this one as I was super tired of waiting and suffering the looks from my wife while swapping these on the wall for testing (133" diag), by myself!

It is quite evident/annoying on bright scenes, but I'll live. Sooo many other things to obsess over, know what I mean? Sorry if this is no help, but I wanted to express that this is not an obscure case.

Thanks for the response! I must say that's disheartening! But at least I know I'm not the only one who's experienced this. You said that one was the new 2.4 - the others were the 2.8? They all had striping of some kind - whether vertical or horizontal?

I called DaLite today and spoke with a representative. He made it sound like this was something he hadn't heard of before. I even sent over the picture I posted here after getting off the phone, but have yet to hear back about that. He told me they could send me a new screen and even offered to swap for another material (not something I want to do). I definitely can't complain about the support as it's been top-notch from both DaLite and AVS, but the QC problems are another thing entirely. I guess I have to mull over my choices.

Has anyone else experienced this with the 2.4 material?

I know this might be a redundant question but is there really no plan on bringing back the classic high power of 2.8 gain? I have a 10 foot wide 2.35 130 inch diagonal that I'm absolutely in love with. I was thinking I'd go the biggest size they had without a seam.

Oh and one question- how bad do seams look like on Da-Lite projector screens? If I wanted to go 200 inches

Hello all, I'm a long-time owner of a Model B 92" 16:9 High Power screen (original 2.8 gain). I just got a new projector (Epson 8350, though I'm still debating whether I'll keep it or trade it for a different make/model), and I'm planning on moving up to a bigger screen. I may even go with a 2.4:1 ratio. I may go with a fixed 1.2 gain screen, but since I've been so happy with my High Power, and it doesn't look too bright now at night with this projector (and will dim more as the bulb breaks in and I move up in screen size), I'm thinking of possibly going with a Model C High Power 119" diagonal 16:9 screen (again, I may have them custom make it with extra black masking at top to give it a 2.4:1 ratio). At this screen size, and with the extra masking up top, and using the newer 2.4 gain material, am I likely to have more problems with waves than I currently have with my 2.8 gain 92" diagonal 16:9 screen? I've been very happy with the relative flatness of my current screen (and the fact that it doesn't accentuate the slight waves that are there).

Thanks!

I had a bad day yesterday. I have a 139x78 highpower mounted in my theater. i was pulling it down and one of the straps holding it up broke. The screen wadded up on the floor. Now I have spots all over the image. I will have to buy a new scree. I was going to mount the screen in a fixed frame. I still want to do this and remember when I bought this screen a model c was cheaper than just the fabric. Is this still the case and if it is, why? Yhe case has to add quite a bit to the cost. Is there any way to purchase the material cheaper?

My 2.8 HP is 7 foot tall and has seam 1 foot from the top. Yes it is visible on solid white but I rarely notice it during a movie. I think the important thing is where the seam is positioned, if it's out to the edge of the screen then it's not really a an issue but I would imagine if it was across the middle of the screen than it would be unacceptable.
