Discussion - Screens for 3D Projection - Page 9

I hope so - in the main articles I was puzzled by the "...this does not apply to DLP".... and asked myself - so - is that good or bad?? :-)

Acoustically transparent screens have much lower real-world gain than the advertised gain... many are advertised in the 1.0-1.16 gain range when the REAL gain measured with a meter is more like 0.7 yo 0.8. You didn't list specs for that particular screen... you listed specs for the projector. I don't see a "Reflections" screen listed on the Stewart website so I can't comment on that material specifically.

The other issue is... if the RS55's output lumens with a calibrated image is no higher than last year, a screen larger than 10 feet wide isn't going to be very bright for 2D and even dimmer for 3D. ESPECIALLY if the screen in question is perforated and has a real gain below 1.0. It seems all perforated or other acoustically transparent screens have factory gain specs that relate to each other, but they DO NOT relate to the gain specs for non-perf/non-acoustically transparent screens.

If you are stuck on this projector and that large screen size, you need more gain in the screen and that probably means forgetting a perforated or other type of acoustically transparent screen. Seymour-Screen Excellence makes a fabric (non perforated) acoustically transparent screen but the REAL gain is in the 0.75 range so even though there aren't holes in the screen leading to lost light, the fabric itself isn't as reflective as most solid-screen materials.

I understand the desire for AT screens, but in real life I never feel like the sound isn't coming from the screen. I don't know if it is our brains or the processing power of modern ht receivers, but it is fine. I personally can't imagine for a second giving up both screen quality and sound quality for an AT screen.

What are currently the cheapest screens available (please provide a link) for a screen that will do passive 3D?

Don't go too cheap. If you want to save money just get material from a good screen and make your own frame.

I paid like 360 for material from harkness (a very highly rated material).
The cheapest possible would be some silvery material at JoAnn's and some painted method.

If you are going to do a passive setup, will placing linear or circular polarizers over the lens of the DLP work? I know you also need a screen, but is a dual DLP setup straightforward?

Yes, DLP is non-polarized so there is no extra consideration in using polarizers.

Anyone try this company or screen?

It is more than I paid (years ago) for my Harkness spectral 240. It is almost half the gain too. I guess if you have really bright projectors it would be a good choice. I can't imagine not wanting more gain though.

Hi guys,

I went through this thread but I m still not sure what the best screen for me is to pick.

At this moment I m running my Sony VW95 on a basic 1.0 gain screen (from Kingpin, not familiar here probably, but it s a Dutch brand for screens with a low price and good performance). I like the 2D but dislike the 3D on it because it s a little dark. What screen would give me the best brightness in 3D without doing too much concessions for 2D performance?

Last but not least and most important my setup:
VW95 in a total 100% controlled bat cave (everything is mat black, from furniture to walls etc). Screen size would be 100''.
Glasses are the MV3D glasses with the VW95 that I use.

No ideas anyone?

thxz for your reply.

Here s a detailed distances picture of my current setup. Maybe you can advise even more specific with this information:

Hi Guys,

First off, thanks for the great thread and all the info on 3D.

I have a 700 SF dedicated home theater with a 10 ft ceiling, two level seating, light controlled and acoustically balanced environment, etc, etc.

I primarily watch 2D movies, but love 3D when I can get good source material, but obviously the quality of the 3D picture is marginal at best with my 1st generation 3D JVC projector and Firehawk screen (even though most first time viewers think the 3D picture is awesome. but you and I know different).

So, having paged through this thread I have a couple questions you may be able to help me with.

Current equipment is as follows:

JVC DLA RS-60 projector (ceiling mounted just below the top of the screen frame, with 14 foot throw)

Stewart Firehawk screen (132 diagonal with Stewart frame - mounted to the front wall)

8 pairs of JVC active shutter 3D glasses

IMO, the JVC throws an awesome 2D picture, and most definitely blows the doors off my previous Sony Qualia 004 (that died about a year ago).

However, when it comes to 3D viewing I'd really like to try and enhance the PQ if possible.

Questions:

My assumption is a screen replacement would be the best way to improve PQ, other than replacing the PJ?

And if so, what screen would you guys recommend for 2D and 3D viewing (was thinking the Stewart 5D might be a good choice but I need input)?

Any help/suggestions would be appreciated.

Thanks much,

Thomas

no ideas anyone?

Ok still doing research but what seems to be the best screen for both 2d and passive 3d?

i am thinking to buy a silver screen for my projector w/ passive lens ( hd33). what do u recommened me to buy? any suggestion will be nice.

thank you.

Asked this before but still don t have an answer to this:

I own a Sony VPL-VW95ES and the 3D picture is way to dim on my 1.0 gain screen (fixed frame). So I m looking for a dual screen setup. I want to keep the 1.0 gain screen for 2D content and get a motorized screen for 3D. So I m looking a the projecta (dutch brand but same as Da-Lite from what I ve heard) 2.4 High Power screen. Will this screen work in my setup? I don t have my projector on eye height but it s pretty close. Or won t it work in my setup you guys think?

we have this exact setup at our weekend house, DaLite HP and the sony 95ES. Its mounted a couple feet at least above eye level and it's awesome. Bright 3D (and very limited ghosting issues, we use the Monster glasses). 2D is _very_ bright without being an issue in any ways to my eyes (YMMV), but it's easy to adjust (although we're lazy and don't adjust too often unless we're watching sports and turn on some motion enhancement occasionally). We have a fairly short throw distance, and the largest DaLite screen in this material without seams (133" I think). An amazing experience overall, we use for primarily movies.

Looking for recommendations of screens that would work best with my set up. Using active shutter glasses with an infocus in146 2700 lumens 3d ready dlp short throw projector. Currently throwing a 120" image on a blackout cloth screen from only 5ft away. (projector is made with a wide angle dome lens). Projector is on a table just below eye level.
Have total light control, but the walls and ceiling are white (renting). More of a make shift movie room than a major home theater. Projector is bright for 2d viewing, but I'm looking for a screen with some gain for 3d. Will mostly be sitting at center of screen so I'm not too concerned about angle drop off. Since the throw is so short and its on a table, just checking what my best options would be as it will be used for 2d and 3d.

i am looking to buy a screen for my hd33 projector. but i dont kow what gain i shall buy? i need to buy at least 100inches screen.

What is the best 3D screen for retaining polarization?

This is a great case for a Da-lite hi-power.

It would be nice to have a new update on 3D screens. I just tested my Harkness 240 screen. It has been sitting in my closet for 6.5 years and I just hung it from a wire. It wasn't good from my 7' seating distance to the 120" screen. The screen structure was clearly visible. The extinction seemed fine. I now declare that extinction isn't the most important variable for me. Well, at least not the only. It is probably fine from a further seating distance. It did, on the other hand, make colors really pop, even more than my already awesome Vutec Silverstar screen. I really think RTBO is using a Black Diamond 2.x screen to good results. I would personally really like to try the new curved Vutec Silverstar 3D-P screen.
If you don't have perfect light control I imagine you couldn't beat the Black Diamond. Of course without a comprensive (or even casual) test it is all guessing.

I have some samples but the Black Diamond 4K 2.7 sample does not seem to retain any polarization. I did a simple test with the 3D glasses and it does not seem to hold any polarization.

oops, I said RTBO, but it was DRJAM that started the Ultimate 3D projection system thread http://www.avsforum.com/t/1280393/the-ultimate-3d-projection-system-a-practical-discussion-thread
RDJAM said "I intend to use the Black Diamond II screen that I already have at home, as it is supposed to be compatible. (update Jan 11, 2011 - turns out the BD II only preserves Linear, not circular. They have a new 3D version in development which preserves circular also.."

so if you are testing with circular glasses from the theater it won't work.

Is anyone here using the Cinema Vision 1.3 with an Epson 5010/6010??? If so, how are your results? I have the 92" and I worry that maybe it will be too much (not just for 3D) :-D
