Okay, I called up Stewart earlier and good news, my original order for the GrayHawk was cancelled. I forgot the name of the gentleman that I spoke to but he even spoke about this thread. I was suprised. "Wait, you're from New York and you have a MF1 on the way. I read your post on avsforums." Great guy to deal with. Very helpful. I asked for the screen dimensions and I'm going with a Stewart StudioTek 130 @ 2.35:1 @ 130" diag.

I also called Meridian/Faroudja and the gentleman there said that 130" is about max. After that I'd start to lose a bit too much brightness but 130" should be alright. Very helpful man as well.

Mr. Phelps, you asked to know about the width of my screen. The viewable width is 119.5" and the height is 51". It will be flat.

I've searched through the Stewart website to look for masking options but I couldn't find anything that pointed to a fixed screen that has masking. I'm looking for vertical masking but it seems that it's only available to roll down screens. Does anyone know? I get this feeling that I'll have to do a DIY masking once I get my screen.

You need to call up Jason Turk at AVScience and talk to him about a screen. He'll sort you out with a good price and knows about all of the Stewart options. Stewarts curved screens also have masking.

Thank you Mr. Erksine! Couldn't find a fixed screen with vertical masking, only horizontal which I didn't want.

Raoul,

Based on your opinion, would I need a curved screen? After speaking to Stewart Filmscreen, they said it was more a matter of opinion. If my screen was ginormous I would most likely need it but if not, then it's not necessary. How would I take care of pincushioning and a anormophic lens on a curved screen?
post #157 of 1855
What's with your dealer? He should be able to answer these questions for you.

An anamorphic lens (depending on throw distance) can create pincushioning. The curved screen solves the pincushion. In addition a curved screen will improve uniformity. The amount of the curve required would need to come from either Meridian, your dealer, or Stewart. It is likely that neither Meridian nor your dealer have alot of experience with CH 2.35:1 applications (yet) so Stewart may be your better source; however, do your dealer the courtesy of informing him that you wish to speak to Stewart directly.
post #158 of 1855
Just call Jason at AVS, tell him your projector, order your anamorphic lens through him (with your rig it seems like you're in the ISCO3 league) and then they'll work out, with Stewart, what the curve should be.

For a screen your size, a curve is encouraged.

I also agree with Denis, call your dealer and tell him you're ordering your screen through someone with experience in this area.
post #159 of 1855
I DID speak with Stewart and the gentleman told me that it was a matter of personal preference unless the screen was like 150"+. I also spoke to Mr. Pointdexter today about the ISCO and he's running a 150" flat. I don't think it'd be a problem. I'll have to call Stewart one more time tomorrow. Is there anyone that I should specifically speak to?
post #160 of 1855
You can run it flat on 120" wide but you really do want to have the curve for uniformity. Mind you, on a Studiotek, the difference will be smallish. Don't sweat the curve too much if it's going to be hard however it looks like you're going top end all the way with the ISCO, Projector, etc. so you shouldn't cut corners on the screen.
post #161 of 1855
Invest in a plane ticket and come to Atlanta and see our 120" curved screen and ISCO lens. I would also differ with Stewart in that the choice is based on physics (throw distance, optics, viewing angles).
post #162 of 1855
Yes, I know what you are both saying. I'm awaiting an e-mail from ISCO for recommendations based on JVC's HD10K since the Faroudja uses the same lens. My main concern was pincushioning since the MF1 doesn't have any keystone adjustments. They're not big on it.
post #163 of 1855
Is the Faroudja the same as teh HD10K or the HD2K?

Did you try using:

http://www.jvcdig.com/lens_calculator.htm

the lens calculator there will let you work out what your image will look like when you dial in the correct numbers.

Other person to speak to about this is Phelps as his name is on the product. Be sure to send William all your info when you do send it for calibration, mount orientation (table or ceiling), send him the lens and if you buy an exotic screen, send him a screen sample to calibrate against.

The Faroudja DILA-1080pHD is based on the HD2K and the DILA-1080MF1 is based on the new HD10K which is what I'm getting.

Raoul, thanks for the suggestions. Mr. Phelps and I have e-mailed eachother a few times already. I don't think calibration is neccessary right now since the calibration was done using a Stewart StudioTek 130 screen which is also what I'm getting. I've also spoken to Mr. Rawls at Faroudja who happens to live in NY. He's doesn't have an opinion yet on curved screens but he'd wants to come by to see my setup for 2.35:1 purposes as they are working on a lens solution as well. I'd wait for Faroudja's lens but I don't want to put this off any longer and I'm pretty sure they will be using ISCO's as well.

If going with a curve the 1.5 gain might even make sense because of the reduction in hotspotting that the curve would provide. I don't know if their 1.5 gain material has any other downsides compared to the 1.3 gain material though.

I agree. I thought about that but didn't want to upset CChoi any more. I mean, why not go for the VideoMatte 2.0 and have Phelps calibrate accordingly?

Because with the StudioTek, I most probably won't have to. This is an enjoyable experience but I don't want it to turn in to a hassle. Obviously, it takes time to do things right but right now, I don't want to spend any more time than I have to. ETA for my equipment (except screen) is due next week, Thurs-Fri. I'll get everything ready, get my screen, and if it needs to be tweaked, I'll send it to Mr. Phelps. If not, even better.

Raoul, using JVC's lens calc, it seems as if I will have a problem with keystone and pincushioning. I'm not sure if I'm doing it right. Not to mention that my dealer and I haven't exactly decided the mounting height/distance. We're both guessing anywhere from 19-22 feet or so. The room is 23 feet deep. Don't forget that I'm adding the ISCO III so the longer the better. Or am I thinking wrong?
post #168 of 1855
The lens offset on the JVC is designed so that if the projector lens is at the height of the top of the screen you'll get no keystoning. Similarly, if it's a table mount, the projector should be at the bottom of the screen. Design your projector mounting accordingly.

Not in this case. The DILA1080-MF1 has lens (image) shift.

oh. very nice. so then will he get keystoning?

I just did a busy bit of testing of UM 150 and ST 130 anticipating UM's 1.5 gain being necessary in my application. Thought you would like to hear results.

Although capable of an extra foot lambert or two, Ultramatte had some idiocyncracies that bear mentioning. The higher gain makes a very unforgiving surface; the slightest undulation being very visible. I am more aware of the surface of UM. The gain causes that, and the surface has tiny little sparklies that attracted my attention too much at times (high luminance in program material).

Uniformity was an important issue to look at. Edge (last quarter of area) luminance was interesting. Of course the PJ naturally has probably 10-15% edge fall-off. The gain of the screens compounded that...depending. UM had the most serious fall off, about 35%. ST was less pronounced, but cumulatively more than is allowed in the DCI digital cinema specs. It seems the most improvement on this would be made using a curved screen. Further testing revealed that ST 130 would do very well with a curve and get edge luminance up to within the DCI digital cinema specs and tolerances (actually very near the nominal specs; DCI specs nominal, and tolerances for both reference viewing theaters, and commercial theaters).

Not if the image shift is adjusted properly. That's the point to having image shift.
post #173 of 1855
I'm installing an Optoma HD72 DLP projector in a fully light controlled room. I am planning to use a 100" Stewart screen. The projector will be mounted about 12.5 to 13.5 feet from the screen. My front seating will be probably about 12 feet from the screen.

I am trying to decide what fabric to use my dealer says I could go with either the Firehawk or Grayhawk?

Any advice on which way to go or other alternatives to be considered?
post #174 of 1855
I am about to assemble and install my 110" diag Firehawk. I have heard that these can be quite tricky to hang, although in searching this thread, noone seems to have asked this question. Are there specific tips, or is it simply not as hard to do as I am imagining? Thanks in advance.
post #175 of 1855
I'm between a Screen Research 110" wide 16:9 and a Stewart Studio Tek 130 w/Micro Perf. Does anyone know the retail pricing for the StudioTek in the size I'm looking for?

At this point, I think price is the only factor I'm looking at between the two screens, but if someone has opinions as to the firehawk or other offerings please chime in. I'm planning on using the Optoma H81, which is not released yet.

ScreenResearch is 0.9 gain. Stewart StudioTek 1.3 gain. The StudioTek will appear brighter. The StudioTek w/ MicroPerf will require equalization, the ScreenResearch will not.

Yes, I'm familiar with that information. The nice thing about Stewart is they can microperf any of their screens, so if I want a neutral screen I can go that route.

THX requires equalization, but I know HAA recommends rolling of the high frequencies, and some say do NOT use the Stewart equalizer because you actually want the roll off (obviously an area of debate, since THX requires the EQ for certification).

So, back to my first question - anyone know pricing for Stewart? I don't want discount pricing because I know that's not allowed, MSRP is fine.

Thanks,
SimpleTheater

If memory serves, a 110" Luxus Deluxe ScreenWall fixed screen (not a motorized drop screen) is around $2,400 MSRP.

Thanks, but I doubt that's w/micro perf or Screen Research would be out of business.

I'm getting 110" wide 16:9 quotes on SR for around $5k. If Stewart really is 1/2 the price, I'll go with them immediately.

Sorry, I forgot the key ingredient in the above formula, which is the screen material: StudioTek 130 without perforation.
