hmm, that's a good point to keep in mind.

That's confusing. After all, it works for commercial theaters, doesn't it?
post #334 of 378
Commercial theaters is hardly what you would call close inspection situation like a home is.

In the cinema the colorimetry and color quality of the DCI projectors is the truest color of any projection, period. At home it goes from being a total joke to hardly a joke, never even close to the cinema perfection. So a silver screen would make color even worse at home.

In the IMAX ones you will definitely see massive hot-spotting (partly from the screen partly from the short throw lens). Then there is mottling a faux painted like unevenness of the screen surface which I have seen on every spray on silver screen except one MBI I saw yesterday in LA, but this screen had 15 db roloff of high frequencies, they have talked about future micro-perf version.

So the cinema projector is going to exhibit less color shifting and other anomalies due to it's auto-calibration to the silver screen.

The silver screen are problematic a handful of ways, the mottling on sprayed on units, the lack of a woven silver screen will yield sound problems, there will be hot-spotting like on IMAX, and finally my chief offence is the irritating visibility of holes in the Hurley silver screen where the holes call attention to themselves, creating a badminton net effect-smack in the middle of the Percival zone of comfort (the 3D action stage envelope between the tip of you nose and the back of the stage).

Peter. In furtherance of your point, much of life is all about pushing one`s self OUTSIDE zones of comfort. Our home`s, and their HTs within, must provide a recharge refuge TOTALLY within our zone`s of comfort, percival or otherwise. Now I must run and buy a box of shuttlecocks.
post #336 of 378
Harkness hall has a regular perf screen and a micro perf for smaller screens.
Gaa. If I wasn't so dang lazy I would have my 3D screen up now.

LG Announces CF3D Projector Coming Soon

Quote:


LG Electronics unveiled this year, their latest projector, the CF3D. This model features 2500 ANSI lumens, a 7000:1 contrast ratio, and full HD (1920 x 1080) resolution. It is considered one of the first projectors to display 1080p content in 3D. Today, LG announced that this projector will be available soon in the UK. Unfortunately LG has not released a lot of additional information other than it will come with dual HDMI ports as well as a USB port. The best aspect about the CF3D though is that LG announced that this projector will be shipped with up to 6 pairs of 3D glasses, which is enough for a full family, plus some guests. This is significant because most companies who are retailing 3D devices only include one or two glasses per device. LG has not released an exact release date yet, but it will be priced for $9999.

That's such a silly write-up because it misses the main point of this PJ which is that it's passive 3D... so a family can just take home the free 3D glasses from their local theater and they'll work at home.

Theater glasses may work or not as there are several different polarization schemes used in commercial theaters. In any case, glasses with polarized lens are really cheap to buy, but you do need to know the specific configuration that LG is using. Eyeglasses may use lens that are either linear or circular polarized. For example if linear polarization is used you need to also know the specific orientation axis of the polarization for the right and left eyes as required by the projector (there is no universal standard for this but they will always be separated by 90 degrees).

Agreed.

At CES it was stated by LG that it used ciruclar polarized. At least that much is consistent with the usual REAL 3D projection in most moviehouses. My guess is LG would keep the left/right rotation issue the same as REAL 3D for simplicity for consumers who would be prone to take home the glasses, but naturally nothing is for certain.

That will be so nice. It would be perfect if it was laser though, like the HDI display. It is a little funny bragging about having more free glasses, when those 6 glasses cost less than 1 pair of active glasses. That, and the 10 grand price tag.

Exactly, which was why I thought that the write up was less-than-scholarly since it made such an obvious blunder of mixing apples and oragnes (ie, that free passive glasses isn't comparable to free active glasses).

Laser on LCOS may be here sooner than we think, though the LG is indeed blub-based.
post #343 of 378
Imax uses linear polarizers. Booh


And one should not steal the glasses from your local theater anyway. They are cheap enough to buy better ones anyway. But no way am I ever going to get a passive 3D projector using polarizers.

There are 600 $ active glasses = reald CE4

And there are 600$ passive glasses INFITEC Super Duper Side Blinded Pro.

So in reality one must look at the specific product benefits and build quality.

No?

No?

Talking about "reality" would negate $600 glasses whether passive or active, no?

I think it's reasonable to state that passive eyewear costs substantially less than active eyewear given whatever performance target is the goal. The fact that somewhere out there are products in both categories that are outliers on the price-scale doesn't change the reality inside the bell curve of excellent consumer-oriented eyewear.

I'm thinking of getting the Viewsonic PJD6531w.

Here's what I know:
  • Bright @ 3000 Lumens
  • hdmi 1.3b, so only way to get 3D is by PC or Mitsu adapter(if that works)
  • I have HTPC with Nvidia GT240 and PowerDVD 10 Ultra 3D Mark II so I think I'm good to go
  • I have Optoma DLP link 3D glasses, so they should work

I'd like to know from anyone that has used this projector for 3D viewing with shutter glasses using a Bluray 3D source disc like CWACOM, Ice Age, MVA, Grand Canyon, etc.

Also curious of other success stories of 3D front projectors playing true Bluray 3D source material. TIA!

The current crop of 3D-compatible DLP front projectors require frame-sequential input. The Mits adapter will not provide this.

Optoma has promised an adapter (un-officialy see quote) for handling direct tv and BR discs for the HD66 projector by the end of the year.

See post #635 of the following thread:

http://www.avsforum.com/avs-vb/showt...0#post18841790

Have not heard similar statements yet from Viewsonic.
post #349 of 378
Well if I had an Infitec based system, I would spring for the top of the line ones. But we are talking polarized glasses here.The best ones assuming they are the right ones for the polarizers in the projector are much less expensive.


Peter. Look at the Cedia 2010 thread in the $20K forum and sign up for one or more dinners.

Good to know. Is this the format that cable cos. will eventually transmit or frame packed SbS?

At the end of the day, I want the Front pro. to display from two sources -
1) Bluray 3D from my HTPC with Power DVD 10 Ultra 3D Mark II Update
2) Cable broadcast 3D (when available, I think this will be SbS frame packed)

using:
HTPC with Nvidia card (GT 240), HDMI 1.3 cable already buried in ceiling, Optoma DLP link glasses

Do any of the current 720p 3D ready models fit this bill?
post #351 of 378
1 isn't a problem I think, though I haven't tried it. 2 of course is going to need a converter. Current 3D tv's are converting frame packed 3D into frame sequential internally since they end up displaying the same page flipped 3D as current projectors and all 3D computer monitors. There isn't a really good reason they couldn't make an external adapter. The LG projector must be internally splitting the packed signal into two seperate signals for each light engine. An external version of that adapter is what I really want so I can play 3D bluray/PS3 on dual passive projection.

CBL and SAT use the 3D format called Frame Compatible. That means the bandwidth is the same as a normal HD signal. It is either SbS or T/B. You lose either 50% of the Hort. res (SbS) or 50% of the Vert. res. (T/B) Only 3D BD uses Frame Packing (1080x24P for movies and 720x60P for games) and provides Full HD per eye. (1920x1080 or 1280x720)

from dalite's material selection guide:
3d virtual grey
gain: 1.85
viewing 1/2 angle: 11 degrees

I seriously hope that is a misprint, but given it retains 99% of polarization, I'm guessing it is indeed 11 degrees. ouch. I would NEVER consider a screen with 11 degree half angle... that means that sitting in the prime seating position with a 36 degree viewing angle (THX recommended for 16:9), the edges of the screen would be significantly less than half as bright as the center. I , for one, do not want to feel like I'm watching a movie in a tunnel. Two screens is far and away still best option, IMHO.

All of the screens that claim to retain polarization for 3D seem to be limited to a half gain point of around 10%. That's one reason that for home theater use most people will need a 2nd screen for their 2D viewing.
post #356 of 378
Harkness Spectral 240 is better.
Max gain 2.4
Half-Gain Angle 24%
Extinction Ratio on axis > 130:1

post #357 of 378
I hear the severtson is good and the stewart better.
post #358 of 378
The Stewart Firehawk, a popular 2D screen is 30 degrees, not much better than the Harnkess 3D

The Stewart Silver 3D is 15 degree half gain.

I am thinking the Harkness could be a fine one screen screen. Maybe this weekend I will get off my butt and mount it.

Thanks Ron, that was a great read. I especially found it informative in the comments section describing how the Osborne computer announcement of a new and improved model led to the company going into bankruptcy because sales of their only existing product stopped immediately while everyone waited for the new model that could not be brought to market soon enough.
