have you seen a black diamond screen in person?

you can order any screen size you want, my guess is that most if not all of their screens are custom made.

I will start with the Black Diamond. It really isn't worth it in a light controlled and properly treated room. If you have light colored walls or in a living room, then a BD has some merit. DNP also makes some nice screen for that type of environment.

Dave brought up what I was going to mention and that is CIA. For your theater, that might be better since you say you watch a lot of 16x9. Mark_A_W made a 4 way masking systtem that you could try and probably would not cost a lot. I think Craig did one as well. Instead of using an A-lens and if 817p bothered you, you could go to the pseudo 4k on the JVC RS55.

For the screen, I would try to see if I could use a Hi Power. Looking at the Model C page, you have two options 65"x116" for $804 retail or 78"x139" for $1k. I know Dave and I talked about this in the past, but I am a brightness junkie. It seems like a brighter image can help make up for the lower on/off cr. I remember seeing 20ft/lmbs on a 14 foot wide screen and not really thinking about the lack of on/off cr.

Where do you buy WilsonArt in Canada?
What dimensions is it available in?
What surface finish is best to use?

One note about masking since it has come up. My solution may be a common one, but I had not seen it when I built my CIH screen. Due to the fact I was building a laminate screen, masking was easy to solve. I bought the velvet from eBay for the border, I bought extra for the masking. The way I did the masking was wrapping two foam core sheets cut to appropriate size. Since laminate is solid, I literally just duct taped some magnets to the back of the laminate. On the back of the foam core board, I put washers covered with velvet. To mask, I just pop the panels on, to unmask, I just grab them off. Easy peasy. Less than $40 for a good looking masking solution.

Another question for you guys while I ponder all this:

Install closer to the screen (low throw) maximizes light output but minimizes contrast ratio. I want to maximize contrast ratio so i'm assuming that means installing as far back as possible but still keeping reasonable light output.

So how much does contrast ratio vary from one end of the throw range to the other? Is it major? Or very minor? I tried to look for hard/fast numbers for the RS40 but came up blank after a few searches, and don't feel like reading 3000+ page threads. Wink

Edit: I found this:

As far as TD is concerned, there is another factor. If you are using an anamorphic lens, the further back the projector then better the image (the less color fringing and such). So, if you consider an anamorphic lens, you could factor that in.

My PJ is installed at a fairly short throw as the longest throw for my PJ put it at a bad spot--and again, I don't find the fringing that bad.

As far as CR, in normal viewing I didn't notice a big difference between close and far on my PJ as I tried both.

Two more questions:

1. How are studios doing with keeping subtitles within the active image area for Blu-ray movies? This is a must-have for anyone with a CIH setup. (I tend to watch a larger percentage of foreign films than probably the average person. I've never really paid attending if the subs are inside or outside the active image area since on a 16x9 I always see them.)

2. How do you CIH guys handle a movie like Dark Knight that has variable aspect ratio? You can probably count the number of movies like this on one hand (not much of an issue), but I'm curious nonetheless.

Thanks I'll have a look at those stores.

I think Cine4home measures cr for both min and max throw. You could check their reviews.

for subtitles you can always remux the films to a bd folder using tsmuxer and use bdsup (a java program) to move the subs inside the active image area.

here is a google doc that is updated frequently that lists if subs are cih scope friendly.

Kal if you use a pc for playabck you can use arcsoft tmt5 this allows you to use your mouse to drag and drop the subtitles wherever you want while the movie is playing. This is likely the easiest and cheapest solution.

Maybe curtpalme should start selling oppo bdp-93!!!
