Looking for screen material to build a screen for my G90 projector. I have 100% light control in my theater with a narrow viewing angle. I'm considering Hurley Silverglo for its 2.3 gain. I searched and a couple of threads were returned but not much info on this material. One thread for their Superglo material complained the maximum height was 51" and I wonder if Silverglo has the same limitation. For my application, Silverglo seems ideal. I especially like that it can be ordered with grommets installed every 6 inches. Anyone used this material and how did it perfom with CRT.

Hello

What screen width are you intending?


.

I use the unity gain Hurley for my 13 foot wide 2.4 aspect screen. they have seams in the vertical direction and I can not see them unless I go right up to the screen. its a fairly nice screen for not too much $$$.

Int he screen thread I have pics of how I made my frame from pipes and copper pipe stand offs. I still have to finish it off. lacing is a pain
make sure you buy plenty of rope. It might be a good idea to buy it from hurley as they'll give you the correct amount. I was short and had to use two sections of rope.

the only time you should go over 1.3 gain with CRT is if your using dalite high power fabric. Otherwise the silver this and glass bead that that 2.3 or 2.5 screens look like total sh*t. A customer of mine has the glass beaded 2.5 and I can't believe he can live the "Liberty Pop" look of it.
Left side shifts red, center is sorta white, and right side is blue.

Nashou, I really like your simple frame design. I may give that a try. You just need to build a border to slide over the tubing to finish it out.

I'm considering a frame that tilts out so I can decrease keystone but may not be worth the effort and I'm not sure if I would like watching a tilted screen. As you know, the higher the gain, the more surface defects are revealed. What is barely noticeable at unity may be very obvious at 2.3 gain. I am wanting to build a viewable 96" x 54" area. If I'm limited in height, I'll design to a wider format to keep it seam free. I mostly watch BD with program material that is wider than 16:9 anyway. No wear on the tubes yet so changing screen format won't be a problem.

Dragamm, I agree glass bead is inferior and would not consider it for HT. I think Vutec Silverstar would be the most comparable to Silverglo. Haven't seen it but from what I've read, Silverstar is a respected screen material but I don't want to spend what one would cost to get it to my door.

I'll probably go ahead and order it tomorrow unless someone who has actually seen it used with CRT gives it a bad review.

Just realized Dragamm's popsicle represents color shift/hotspotting. The Hurley rep., Gorman White, claims Silverglo doesn't have those issues. I suspect there has to be some with such high gain. Gorman tells me he is very familiar with Silverstar and Silverglo is superior. Maybe just sales talk. The material is not crazy expensive so I don't mind changing it so much.

If you can afford it, the Stewart Studiotek 1.3 is the best material for ANY projector, CRT or digital. It will perform wonderfully with your G90!

I would say give it a try, but it should hotspot with that high of gain. Tinman has one and says it doesn't hotspot that badly. I guess this will be an experiment into what you can live with. Usually a Torus is the only way to tame a hotspotting high gain material.

we recently tested 3 swatches of dalite fabric at my friends house. highpower, dematte, and cinevision. Granted we were only using a flashlight to get a rough idea on gain but The highpower blew them all away. Even with someone standing and pointing the light downward from the ceiling you lost maybe 20% but still much, much brighter than the other 2.
The cinevsion was the worst but both it and the dematte were very dull, like someone hung pieces of dirty linen on the wall.
Good luck with the silver stuff, I haven't seen it so can't say for sure but the 2.3 gain with CRT and 3 separate light sources is a lot more difficult to deal with screen material wise vs. a bulb machine and single source of light.

I had a sample of "silverglo" from Hurley it did shift red all over the place. There were glowing red auras around most things. I did not use it because of that. I went with the Wilsonart DW -354 material. Wilsonart works great and is pretty cheap too.

[jcwhite57]

Dturco, how did you test the Silverglo sample and what do you mean by "red shift"?
I wish I could get a torus screen. The only source I've found is Mocom out of Korea. Not gonna pay that much for a screen. Especially sight unseen.

I submitted the screen specifications today and am waiting on a quote. It may take awhile to get the frame constructed and screen mounted but I'll follow up with screen shots.

I love my Studiotek 130 G3 made a huge difference in pop over my unity gain screen. I do see a bit of hot spotting when projecting an all white background but on video material I really never see it. I picked up the screen used so the cost is reasonable. The Wilsonart laminate is supposed to be very close to the Studiotek and I probably would have gone with that if I hadn't found a used screen fairly cheap.
