GreyHawk.. I like the name. http://www.avsforum.com/ubb/smile.gif Does the "88" correspond to the gain?

Thanks,

Dear Dpanko,
First of all you spelled it better than I. Yes... the gain looks like around point eight eight. It may vary some on the first production run.
Regards,
Don

Don,

If you're planning on shipping the beta screens in mid-December, will you show it at the Jan. CES in Vegas? Would I be correct in guessing that there are no problems with perforating (or micro-perforating) the screen? Also, can you give us any more information on the material? (like how much more "black" is attenuated than white? ...or will it be ready by summer 2001?)

Thanks,

Kam Fung

Dear Kam

Fung,
Here are the answers to your questions.

1. Yes...we will show the GreyHawk screen at CES...we also hope to show the BlackHawk Light Pipe rear projection screen at the show.

2. And yes, the GrayHawk will be available with the THX micro-perf option.

3. I would like to have the screen available to ship by early February 2001.

I do not want to technically describe how the GrayHawk works at this time.
I can tell you what I "subjectivly" observed today in the lab. Our people fabricated the GrayHawk screen material and the Studiotek 130 screen material into a split screen within the same screen frame. We projected all type of images from various DVDs and would freeze frame different scenes to evaluate the images. The black levels rivaled the black level of the best CRT projectors. The really good news is that we were able to maintain the upper gray scale with minimum contamination to whites. In addition we proceeded to project on the screens with 18 foot candles of ambient light falling on the screen surface. The GrayHawk screen preserved contrast ratios at least 4 times higher than our own Studiotek 130. I am truly excited about this product and we can't wait to get it out to the Beta Testers.
Regards,
Don

Don,

Is it too late to sign up as a beta tester? I have the Runco VX1c, Sharp 100 and Sony 10 setup as demo projecors. I would love to see what this new screen can do. I also have access to a D-ILA projector.

Thanks,
Dan

Don, Do your initial production plans for the GreyHawk include manual pull-down and 16x9 varieties? What about screen material for DIY?

Thanks,

Richard

Dear Richard,
I believe that most commercial screen manufactures such as Da-lite, Draper, Stewart etc. will be more than happy to sell screen fabrics only. This is a good compromise for the DIY crowd. It allows the DIY to have a professional
optical screen surface and still get the economy and self satisfaction by fabricating their own screen frame. The screen frame can account for 50 to 60 percent of the total cost of a commercially built screen.

All Stewart screen fabrics are available in manual pull down roller units.
I would like to add, at the risk of making some people upset, that pull down screens were never intended to be in a home theater environment and should only be used as a last resort. I would prefer to see the customer built their own screen frame and purchase a quality screen fabric from one of the screen manufactures. To me a pull down screen in a home theater is like having a GPS in a Yugo, a butler in a mobile home, etc.

Hi Don,

I don't mean to misdirect the topic of this thread, but I was wondering if you've been following the Do-It-Yourself screen topics in this forum. A number of us have been experimenting with various paints, fabrics and other materials to replicate and perhaps even improve on the commercially sold screen. Certainly your input and experience would be invaluable to us. Without giving away any Stewart Screen secrets, is there anything you can add to the discourse of screen making? In order to not hijack this thread maybe you can answer me here:

Don,

Thanks for the prompt reply! Do you know if the GrayHawk screen will be sold at the same price as your other more conventional screens, or will there be some sort of premium?

Also, looking at the added cost one pays for a micro-perf screen (and other perforated screens) I am sorely tempted to attempt some sort of DIY perforation. Would you recommend attempting something like this? The 8 ft. ceiling in the planned theater means I have to place my center channel behind the screen and perforations of any kind seem to add a great deal to the cost, especially on a 6' * 10' screen.

Thanks,

Kam Fung

Dear Kam Fung,

I am 99 percent sure that the GrayHawk screen we be the same price as Studiotek 130, Videomatte 200, Etc.

In regards to trying to perforate a screen that was originally purchased as a solid screen I beleive it would be all but impossible to DYI your own perforations and receive satisfactory results. Well... Maybe... a few shotgun blast would do the trick?
Regards,
Don

You know those funny labels you find in the strangest places, like "Don't try this at home?" or "Don't Smoke near a Gas Pump!" It's because someone did in fact try it.

Don,

I wasn't really keen on the idea of poking all those holes anyway http://www.avsforum.com/ubb/biggrin.gif How do you perforate your screens on such a large scale (both volume and size)?

Kam Fung

Don has got this great "crew" of old ladies that sit around his shop.
Instead of quilting or playing bridge all day they just poke holes in the screens.

I must admit, they do a great job! I have never had an issue with ANY of the pref screens I have ordered!
