Discussion - Screens for 3D Projection - Page 10

post #271 of 288
Good info thread
post #272 of 288
I have over the past few weeks considered replacing my old Stewart Firehawk with a Dalite High Power since the 3D picture from my Sony VPL-VW95 seems so dim.

However I ran the calculations of both screens using the Simple 3D Projection Calc spreadsheet - and it appears the brightness using the Stewart (1.3 gain but maintaining
60% of polarization based upon information provided in the first posting) is actually greater than that of the Dalite. I'm claiming 1.9 gain for the Dalite since the projector placement is less
than optimum for the screen. Using "0" for the percent of polarization maintained for the Dalite gives me a brightness rating of 10.6 fL compared to 11.6 for the Stewart.

Anyone care to comment or confirm?

Describe projection room. Is it a dark man cave or traditional family or living room? Are you plan to watch in complete darkness or with some ambient light?

New developments.

I am putting up a new home theater for basement.

came across this option for projector:
epson w16sk

http://www.epson.com/cgi-bin/Store/jsp/Product.do?BV_UseBVCookie=yes&sku=V11H494020&cookies=no#2

what do you guys think?
granted it is not 1080p -- but could it still be used

which screen is the most reasonable for passive 3d ( and should be good for 2 D also)for the money paid--what is your recommendation?
1) stewart 5d
2) da-lite silver lite 2.5
3) vutec silverscreen 3dp
4) harkness 240 material -- to be put on a screen

I think it would be waste of money and your effort. Why bother setting up wxga projector system that is also not capable of handling full hd? As Epson website says "Good for classroom" and I add not for your home theater. There are so many reasonable priced full hd pj's out there. Look for these and take you time. Good luck.

Anyone tried the Elite AcousticPro 4K material for 3D? I have a JVC RS-4810 with that screen material and I'm struggling to get good 3D (glasses are MonsterVision Max3D) no matter how much I tweak the settings on the RF emitter or the projector. Starting to wonder if the screen may be culprit...
post #278 of 288
Well, JVC's are known for poor 3D, so that may be the problem too. I think the compromises of an acoustic screen just aren't worth it personally. Also higher gain would be good.

Guys I need a help.

I own Acer HD5370BD which is 720p, 2500 Lumens and 13000:1 Contrast.
Needless to say, I use it only for HT purpose.

I have tried different screens at my place (considering availability in my region and constrained budget), I found Grandview to be the best of lot. I was not completely satisfied with the PQ and thought 5370 is just an average PJ and cant expect much from a $400 PJ.

I strictly use in nights in my living room which has light coloured 1) walls, 2) ceiling and 3) flooring, Probably Low Ambient Light..

However, when I projected 5370 on a off white wall, results were Amaaazingly Good. Beautiful Colors, Superb Contrasts, Amazing Depths in Blacks and 3D as well. I am blown and completely satisfied with the results.

Whatever screen I have tried were Matt White with gain of max 1.1. Issue I feel with Matt White screen is it looks too washed out. Blacks are mainly washed out and becomes PQ fades. Contrast is also eaten up by Screen. Colours become dull and lifeless.

So I was wondering to try out Carl's DIY Matt Grey screens which don't cost a fortune.

So my question is will Matt Grey be suitable for absorbing unwanted white levels and produce more depths in blacks. Also I want to know whether I can use it for Active 3D ?

Thanks Again !!

Interesting, I was thinking about using the same High Power and for the same reasons. I have my PJ in the same relative position as you have and the calculator shows the same gain
in my front main seat as you have calculated.
I have tested the Da-Lite 2.4 ( samples) against my Screen Innovations Solar 4K 1.37 gain white screen and it does show a reasonable amount of gain in the best seats, the wider seats
only 25 degrees off axis are about the same gain as my fixed screen which is 1.37. My Solar 4K does not maintain polarization so there is no benefit . If you do not intend to drop your PJ
and the Stewart will give an equivalent brightness due to the polarization retention then it would be wise to stick with the Stewart . The new FireHawk is only 1.1 gain BTW are you referering
to that one or your older original screen?

The Stewart is expensive I would never buy that unless they gave you samples to test. Good luck with that as they refused to send samples to me. Apparently, they do not believe in this philosophy
and will only sell a screen based on their suggestions. Hmmmm, ever other manufacturer sent me samples and I'm glad then did as MANY are not even close to what they advertise. The Da-Lite
high power was everything they advertised btw, one of the few. And in case you do go for the Da-Lite, I can tell you the Elune Visions 2.4 is the exact same material and does work the exact same
way.
The Stewart products intrigued me but without samples, I don't think so, not at the prices they are asking. Instead, I'm going to make a Torus screen from Sintra and paint with Silver Fire. This will give
a much better picture that any of the manufactures and it should be done including the paint gun for under $1000, well under in fact, maybe two screens wink.gif

My Vutec Silverstar is amazing for 3D. I am really wanting to get a Sony projector with the manual iris so I can turn down the 2D brightness. 4282 hours on my Epson 5010's bulb, still on eco mode and it is still a bit bright. 3D is sure amazing though.

Is that the old 6.0 Vutek Silverstar? The new one has issues they will not sell it or even send out a sample.
post #283 of 288
Yes, the old one. Hadn't heard that about, or almost anything, about the new one. I was thinking of going passive 3D and getting the new curved Silverstar 3D-P.
post #284 of 288
I haven't been able to find much about the Silverstar 3D-P from real-world users or reviewers but I'm about to order one for my Panasonic PT-AE8000U so I'm going to find out first hand how it is. if there's anything noteworthy, I'll post it here.

The new Silverstar 2.2 is around the corner, it is ISF certified too ,so it may be a good idea to wait . Many liked the older Silverstar 3D P but it certainly had its place . That panny is bright , I assume you will be lighting up a rally big screen or intending to do a lot of 3D viewing as
the original is like 3 gain.

110" 2.35:1 with a 23' throw distance.
Had no idea a new one is coming but the room is nearly done except for screen and carpeting g so I'm not sure I could just wait for something new at this point. Jeez, I hope nothing's wrong with what I'm ordering. I loved my old Silverstar from 2006.

If you had the product before and enjoyed it then you will likely be more than happy. The new ISF certified product , the 2.2 was shown at CIDIA in the fall. ISF means it has less color shift and grey scale shift than others not certified. In the bigger picture( excuse the
pun) that means diddlysquat . I have now tested over half the manufactures products in my search for a higher gain screen to use for 3D. Only a couple have been acceptable and what I mean by that is, they have been close to the product specs as advertized.

Bottom line is test first because you will not get your money back. These screens can cost an arm and a leg and it is wise to be sure before you take the initiative .

The 3D-P is for passive. You probably don't want that unless you are doing dual projector passive. It is curved to lessen the hotspot effect that comes with polarization maintaining screens. With a single projector and active glasses you want the 3D-A screen.
