I had three High Powers. That's all I have used for 6 years. I love them. But I just learned something new:

The brighter your projector is, the better the High Power seems to work off axis. I guess it just makes sense, but moving up or down and side to side didn't have a huge impact of the viewability of my High Power when I had 2200 real lumens blasting onto it. I have a side sofa that is only used when I have too many people in the room. My kid was watching the newer, lower lumen pj from there tonight and complained, for the first time. It was there where he first noticed in a major way the difference in brightness between the two pjs. I told him to come over to the other sofa, and he agreed the picture as better than with the old pj from there, but still unwatchably too dim for him off to the side. He used to watch from there quite a bit. So, if you have a truly bright projector (rather than one which is just rated as if it were bright) you will find the off axis performance better than others will.

Of course the reason for this is the eye has a huge ability to stop down and adjust to bright light, so the bright pj/HP combination will suit everyone in the room. Just FYI.

With some black fabric and black tape you could have a real easy masking system if you just hung it down from the case to the same level that the black border was on the 4:3 screen when it is fully down. Hopefully the stops in the roller would allow you to make a masked 16:9 in this fashion by just pulling it down part of the way. And if you weren't going to use it both ways, you could place the masking exactly where it needed to be. Even on the screen if you wanted.

Ok then I'll try it out here:



With this projector (should be plenty bright)



This projector is the first DLP cinema unit with servo lens memories for zoom, focus and tilt, (with 6 memories).

Um, I'm just guessing here, but

Or maybe the joke has to do with the nice cheeks, dunno.
I give up.

The projector is Irised down at 2 points by 2/3'ds (light thrown away), to achieve the highest on /off cr in any digital cinema PJ.

Ok, a bright projector on a big High Power. I'm pretty used to that concept. That was a lot of pictures (and data) for that.

My question is, if I get a 120 inch HP and the seating are is around 12 feet from the screen (with the projector shelf-mounted behind us), is there a chanace that the HP will be *too* bright in that situation (as in, either uncomfrotable or distorting)?


I just purchased a Sanyo Z5 too, and i need to buy a screen with 1.1 gain white matte, 100 inch with light controled room. and the seating are is around 16 feet from the screen (Z5 is celling mounted).
Is this screen fine for me? (100 inch 1.1 gain)
some expert or with the sufficient knowledge could respond to these similar questions. that answer Could help us very much.
Thanks in advance.

There is NO chance that it will be too bright.

I have had my 119 ' HP for going on 5 months now. Ironically I have had less time in the past 5 months to watch movies than normal. I have a Z3 projector and an A2 Hd player. I have the Z3 mounted just high enough that If I am sitting straight up I can see a hair or two on the screen, but I am usually down with my feet up.

I have gotten used to the set up and often think the image should be brighter, but then I remember a. my projector aint that bright and then. I take a paper plate and hold it in front of the screen for a minute or two and say, oh.. yeah!!! If I really need confirmation, I just turn it on during the day. While the sun light still washes it out some, I could easily sit and watch something but with my diy efforts you could forget about that!

I finally hung mine up last night with my pjtx-100.........this screen is pretty much everything as advertised.....I can't imagine a projector being too bright for this screen though...it seems that if it was that you could just dial down the brightness a bit.......this screen is phenominal though in terms of using with ambient light. Sure, other seats might suffer a bit but if I am sitting in the prime seating area I can have every single light and lamp on in the room and still get a good picture.

I just need to retweak all my gamma settings now. anyone else have any advice in terms of how you had to reclaibrate your projector once you switched to this screen ??

The following pdf contains a series of charts giving the off-axis angle
as a function of vertical off-axis distance, horizontal off-axis distance and
seating distance from the screen as well as the corresponding estimated gain for the HP.

Disclaimer: My angle calculations are based on my understanding of how
the high power works (retro-reflective) and the gain estimates
are then obtained from the graph on the Da-lite sight. I do not
warranty any of these.

Also, I am sorry for the formatting but I did not know that we could not post
excel files.

Note: The original pdf file (HPCal.pdf) contained errors that happened
when I manipulated the excel file to convert to pdf. Sorry for any
confusion this might have caused.

I am now thinking of buying a AE1000U with this screen. My question is about the mounting of the projector. My understanding is, if I mount the screen on the ceiling (106" diagonal), the the center of the screen will be about 34 inches down from the ceiling. To get the best picture I should then mount the projector on the opposite wall (16'), at 34 inches down from the ceiling. The ceilings are 90". My question is - if I move the projector up towards the ceiling, say 18" from ceiling, and move the projector closer to the screen, will I lose a lot of the gain I would be getting if I had put it on the back wall? Would I be better off with a high gain angular reflective screen, or would this still give a bright picture?
The room is 16' wide by 17' long by 7'6" high.

Rickvette,

Your eye-level when sitting is about 3-3.5 ft above the ground. If you drop the pj 18"
your vertical off set is about 2.5-3 ft . In sweetspot you should get a gian of about 2
if you sit back about 14ft from the screen.

I am seriously considering buying the HP for my HT room. I happen to have two samples and although it is clearly obvious that the color and brightness are superb. My question, for those of you with HP already installed, is this. How are the blacks? I notice on the 6x6 pieces, that on a dark scene, the HP sample is much lighter than the black I am gettion on my 1.0 gain screen.

I posted this in another thread.
I've had the sharp zv12000K MkII since last wednesday. I have a 119" hipower.

Blacks are superb.

Blacks are so good in fact, I mentioned I see absolutely no need for masking for any non 16x9 formats. When watching material in an aspect ratio other than 16x9, I do a double take because it looks like my screen shrinks.
Blacks will obviously be dependent on your projector and blacks with my panny ax100 obviously weren't as good, but with my sharp projector, blacks on my hipower screen are inky black.

Well that is great news. I have the same projector! I currently use a diy masking solution, so the borders on wide aspect ratio films will not be a problem. I may just have to take the plunge and see just how good this is....of course, this will all depend on cost.

Best price I found was from AVScience. (ordered mine from Jason)
Make sure you get the black case. It's a $15 upgrade and well worth it.

It's great that you have the same PJ as bqmeister. That should allow you somewhat of a benchmark for setting things up. I would also add though, that the black level you see on your screen may still be different than what he sees because of other components in your system. Don't want to discourage you but I did want to add in that one thought. BTW, I agree with bqmeister about AV Science having the best price. It's a great screen. I think you'll be pleased with it.
