I can't seem to find a link to buy a Da-lite 106 model b HP screen. Is it possible for someone to post a link or to PM one?

Great thread and very simple to identify needs for novices like myself.

Thanks in advance.

I have a question about the high power screen and its blacks.

I was originally going to get a Stewart Studiotek 130 G3 (1.3 gain). But since I would need more lumens for 3d [JVC rs40 - soon to purchase from AVS].

Question: Will I still be able to get dark blacks like I would on the stewart? I would more than likely have the Aperture set to -13 as it is a very high gain for 2D.

I really enjoy the blackness of plasmas; wondering if I can still get better lower blacks in 2d with the high power.

Sorry im a newb to all of this.

screen size I would get [ 130" Wide in 2.40 AR or 130" Wide in 16:9 AR. I really havent decided as of yet]

Here is what an owner of both has to say.

The RS40 has a low lamp mode and an iris that can significantly lower the light output. You could also use a neutral density filter to cut more light. Moving the projector towards the far end of its throw distance will lower the black level. You can make blacks as dark as you like with either screen although it's a balancing act since these techniques also lower white. If you want blacker blacks without compromising white you'll need to buy a projector with a higher contrast ratio (RS50/RS60).

The StudioTek 130 and the High Power are both excellent screens. If one wants to view a very large screen or 3D (or both) using a projector with modest light output then screen gain becomes an important consideration. In these situations the HP would be a better choice than the StudioTek.

Well I have a 2.8 HP that is 7 years old and lived through my 3 kids and wife(she helped me clean the screen once..uhhh) I am needing to replace the screen. I love my HP with my Panny 3000.

I have read about the new HP is now 2.4. Is this truly a major to minor down grade as people are making it.

I looked for a while and it seemed alot of people are knocking the 2.4 without any real test except for test patches or opinions. Sorry if I am missing some posts or info. Any help would be great as I am looking to buy a new screen.

Has anyone had both in the same enviroment?

If not I maybe the first...lol

I was the first to find out they were making and selling the 2.4, even Dalite did not know. Read the first post.http://www.avsforum.com/avs-vb/showthread.php?t=1213577
But it is all moot, there is no more 2.8 unless you can find used, 2.4 is the only game in town, so buy and enjoy it.

Thanks Doug...missed that thread. Guess I have some reading todo. I have been so happy with my HP that I havent been in the screen section in years. I am a out of the screen game.

I just up sized my screen from 106" to 120", from HP 2.8 to HP 2.4.

Even with the size increase, I didn't feel that I lost any brightness (in
light controlled basement). The only down side for bigger screen is
now I have little screen door effect from sitting 13ft away. LOL.

I have a Benq w5000 1080p projector.
I think I will see screen door effect on any 1080p projector, right?

Other than the black level, I don't think there is anything I can
upgrade from my w5000.

My next upgrade is 4K, passive 3D, DLP LED, with native 2.35
may be in 5 yrs, I can dream.

DLP, yes. DILA, not so much, but if you like the DLP look a JVC probably isn't going to cut it for you. I view 2.35 movies on my 10' wide screen from 10' back and see no screen door with my JVC RS20.

I ordered a HP Model C 110" diagonal from AVS. I tried searching online and can't seem to find the answer to this. Does anyone know the exact height of the casing that the screen rolls into?

I have a short ceiling in my basement, and will be ceiling mounting it. Trying to measure so I know how much height I have underneath the screen for a hand built entertainment center for my components (if I have enough room).

Thanks if anyone can help out!

Have you looked at the PDF files for installing and specs at dalite.com? Not sure that measurement is there but it should be. If not call or chat with a Dalite rep.

I have taken a look, but the measurements only seem to display horizontal values of the casing. Perhaps I am missing it, but talking to a sales rep is a good idea. Thanks for your reply.

More-over everytime it has to be brought down to 5 feet extension down you have to unscrew and re screw the adjustable column. Just not practical.
I had the same problem with my room. I wanted to get my ceiling mounted projector as low as possible, but no lower. I found the extension column options very frustrating. Then I found out that the extension columns (at least the ones for my Peerless universal projector mount) use a standard pipe thread. I bought one of the standard lengths and took it to the local Home Depot and had them take the pipe cutter to it. They cut it and put new threads on it. And, get this, they did it for *free*!

Thanks

( a special request to people who are using the HP with a ceiling mounted projector... How high is your projector lens from the ground ? Are you still getting good enough Gain as compared to what it would have been if you had table mounted it ? )
My projector is mounted 84 inches above the floor, the center of the screen is 53" above the floor, and my eyes are 42" above the floor. I get a 1.52 center screen gain. I love it. It works very well for me.

In order to solve the problem you have, I mounted my projector directly above the back of the second row seating.

My second row (on a riser) is a sofa. If you imagine looking at a sofa from the side, the part your back leans against is quite thick (about a foot for mine). I mounted the projector directly above that position. Since the sofa is there, nobody can walk under the projector, and it is far enough back that nobody will hit the projector when sitting down.

The missing info to completely replicate the situation you describe is the throw and the viewing distance. Without those you can't figure the angles at which you get 1.52 gain.

Minimum gain of screen: .9
Horizontal width of screen: 139
How high above floor is center of screen: 55
How high above floor is center of lens: 55
distance from front of screen to lens: 190 (at full zoom per JVC's chart)
How far back is viewing position: 138
How far to left or right is viewing position: 4 (my center recliner)
How high above floor are viewer's eyes: 35" when reclined

So I get a screen center gain of 2.06, left of 1.97, right of 2.03

I found that FLBoy's calculator isn't all that accurate for the high-power material. See this post.
I plugged your numbers into my updated spreadsheet, and I get an estimated screen gain of: 1.76, 1.94, 1.88.

True, but he didn't ask for those

The full details:

Which high-power screen? (specify 2.4 or 2.8) 2.4
What is the horizontal width of the viewing area of your screen? 120
How high above the room floor is the center of your screen? 53
How high above the room floor is the center of your projector's lens? 84
What is the distance from the front of the lens to the screen? (Measure perpendicular to the screen.) 178
How far back from the screen is the viewing position? (Measure perpendicular to the screen.) 120
How far to the right or left of the screen center is the viewing position? (Use positive distance for right; negative distance for left.) 0
How high above the floor are the viewer's eyes when seated at the viewing position? 42

I took my 12" sample of a M2500 Draper material last night and just stuck it up with my HP 2.4. Keep in mind I'm using a ceiling mounted PJ. With my head literall next to PJ lens, sure there is a difference and HP is better, but I tell ya, the little M2500 held its own when I sat down. It's not invisible like the HP 2.4 is, there is a touch of sheen, but colors were good, and blacks a touch better. My PJ is about 28" from my head right now when sitting, i have a telescopic mount so as time goes I can lower it. But i was surprised how at how well the m2500 held its own. This is the newer 1.5 M2500 material.

I will be getting a larger screen soon and wonder what you mean when you say you're seeing a screen door effect. Do you mean that you're seeing the dark lines between the DMD mirrors (pixels)? Or is it something related to the screen material? If it is the dark lines between the mirrors, you could try softening the focus ever so lightly and it should go away. By ever so slightly, I mean use a very light touch. You should be able to see the pixel structure when standing right next to the screen.

If you're still aware of screen door after softening the focus, what you're seeing may be related to the screen material (some people talk about seeing a sheen from this screen).

Yes, it is what I mean. I only notice it when on the text (warning, subtitle, etc...) I guess I can soften the picture by loosing the focus, but I probably stuck with the sharp focus.
post #3389 of 3769
Drat! I was thinking of going to a large 2.37:1 screen, but I don't want to see the pixel structure. Thanks for mentioning this.
post #3390 of 3769
the 2.4 material is invisible. Now with your nose less then an inch from it, and no light projected onto it, you'll see the weave of the material. But as for seeing sheen, or textures on the material itself while viewing movies and stuff.....ain't happeneing. It's as much of an invisible material as you can get. The older 2.8 gain material has a slight paisley effect to it during bright scenes, and even then it depends on the individual screen and how it was painted, manufacturing differences and so on. But you can not get the 2.8 material anymore so it's irrelevant.
