Here are some pictures of what I am seeing with the DVI Detective in place. These images are 3D, but same effects with regular 2D and side by side

Think this article was written for us! Anyone know how much this tool cost?

I think that is the same one being release on Oct 26th in the USA.

According to Blu-ray HighDef Digest, these are the upcoming 3D releases.

Sept 14th - Monster House

Oct 26th - IMAX Grand Canyon

Nov 9th - Toy Story 3 - This was listed but I just looked again and now its gone

Nov 16th - A Christmas Carol

Tom has some of you might know was my house guest for 3 days last month where we conducted a full day SpectraCal tralning. we used the 780 which SpectraCal sells. The tool with network analyzer functions costs about $4.2K. The basic machine lists for about $3.5K but with the various add ons and package discounts what you would probably need. Spectracal sells a consumer level pattern generator which does #d patterns for $2K but that is not what you would need for repeater testing and HDMi etc.
I am not trolling here since I don`t sell this stuff.

LIG. I do have Tom`s cell and I am sure he wouldn`t mind talking to you and helping you trouble shoot. He is drving to Toronto today from Cleveland and willl be setting up for a training in Tronto on Monday. Getting all that equipment into and out of Canada customs wise will be a nightmare. You should be getting a half horizontal side by side into the projector from direct TV. I do not have enough experience to help you but Coolcould tellyou if that is the image he gets without the glasses.

I get side by side image, the image shown was 3D image, both are just as ugly along with all 2D channels...
post #488 of 711
Cool and you are way above me on this.

Now you say the DTV is sending a side by side to the projector (receiving the go ahead edid from the detective box after it has been grabbed from a set recognized bt DTV but the box is deteriorating the image (because without the box the 2D image is fine), the the problem could be just a bad detective box. The simpliest test would be to go down or up to a best buy, buy a box, have them grab the edit from a set DTV recognizes while you are there, and then try the new box. If ity doesn`t solve t.he problem, you can return the box. Then we can go from there, the problem being something else in the chain (a cable) that is in the system with the box but not there when the box is not in the chain, or, the worst case, the display itself. Did the tech that updated your display use a 3d test signal tio determine that the projector could in fact display a side by side?

Cool. I can just not see LIG sitting there and enjoying Monster House or Toy Story III. Though I think his dog might enjoy Toy Story III. Barwooooofff. We both have greater Swiss mountain dogs and they don`t bark, they Bahwoooofffff.

NO MAS, I have to pulla Roberto Duran, I give up.

I tried HDMI Plus, DVI Detective, grabbed edid from Best Buy and also had Chris grab EDID from his known working display. Ran Directv straight to Titan using Gefen short cables, I give up on this.
post #491 of 711
Direct TV direct works on 2D fine I suppose? Of course it won`t work on 3D without getting the edid. I am sorry for suggesting things you have already tried. I know you are very bright but sometimes it is a silly thing which flies by you or anyone else. I`d say it could be a bad DTV box but you say it works fine in 2D with the detective out of the system and all hell breaks lose in 2D or 3D with the detective in the system. very puzzling.

Cool`s works so the next thing to mentally examine are what are the differences in Cools chain and yours? Assuming you duplicate his and it still doesn`t work, then what? Something wrong with the projector. Many calibrators own the signal generator Tom wrote about and the 3D update is free, some caibrator might not have the add on inside network analyzer. without a full tster, the only real solution at this point would be to duplicate Cools chain and R and R pieces to eliminate possible defective ones. Damn. Though I am not involved here commercially I wish you didn`t have any problems and could sit back in your great room and enjoy the PGA Championship in 3D.

Just wondering if Dark Time setting on Titan should correspond to response time of CE4 glasses, according to Reald the response time 1.7MS?
post #493 of 711
it should for 3d , yes.

Ah, that is much better Peter. 2.35 14' 3D Bluray Triple Flash is pretty spectacular, light output is fine definately not too dim. Chris you should check out a pair of the CE4's I think you will be very happy.

I don't think now 2 different sets of 3D glasses will work as they probably have different response times which will result in ghosting

That is a great point! I guess having 2 pair better than others isnt going to work out so well.

Lon dont feel bad, Ive tried every DVI detective type device to date and not a single one ever worked or solved a EDID problem I was having. I think these devices are designed for computer to computer monitors and nothing else.

Hi Alan:

Chris and DPI have them working perfectly with the exact same projector as I am using, that is the frustrating part.

After further adjustments in 3 D settings for phase, and realizing one pair of the CE4 glasses left shutter was not functioning propery(the pair I was using), all I can say now is I have watched the most amazing 3D Bluray presentation of Imax 3D Under the sea.

I have not experienced 3D any where near this in a commercial theater it is truly spectacular.

Light output at both 1.78 12', and 2.35 14' was more than adequate, no where near 80% loss as reported by some, I would guess around 40-50% at the most.

Before putting 3D down as a fad, one has to see it properly implimented on a high end front projector.

With the good pair of CE4 glasses I was able to retrun the dark time to the default, so Xpand 101's may work with the CE4, I will let you know Chris as I ordered one pair of X-101's to test
post #499 of 711
Lon. Glad you are enjoying it. But one can not estimate brightness loss by eye because to the eye brightness loss or gain is not linear to the actual brightness here thru the glasses. Professional industry measurements show the loss from the ANSI 2D output thru the entire shutter glass chain to be about 84%. This may very well lead to a subjective loss assessment of 50% or so. Remeber if one doubles the 2D brightness, the eye would view it as about a 10% or 15% increase.

Anyway. I am glad you are enjoying your 3D viewing and I fully concur on the need for a bright big boy projector to do it right. Enjoy.

Lon,

Where did you get the IMAX Bluray? I watched that on Directv and it looked pretty fantastic. Im sure the Blu-ray will be way better! Yes, id love to know your thoughts as to how the CE4 and x101 compare.

Also, I agree completely the image only looks 40% to 50% dimmer in 3D then 2D. I have read about this a tremendous amount and everything I have read confirms what Mark says. The efficiency of a single projector with shutter glasses is about 16% with 84% loss.

If what i read is correct, and most of my info was taken for a nice piece of Barco literature showing the efficiency ratings of all different type of stereoscopic presentations, the light loss is from the duty cycle of the projector multiplied by the efficiency of the glasses.

The projector duty cycle should be 50% but it is a little less efficient because there is a little more separation to help with ghosting. So that gives us a duty cycle of 45%. The efficiency rating of shutter glasses is about 37% due to the polarizing lens. So 45% x 37% gives us about a 16% overall efficiency rating.

But that left me confused as to why my image doesn't look 84% dimmer than what my 2D image does. I think its because that a calculation of actual brightness and not perceived brightness.

So with my 2D image at 40fl my 3D image would be 6.4fl. If that is correct then that is no where near how it looks to my eyes. I think its because that is the brightness that one eye receives at a time. So since the switching is happening so fast my eyes don't realize one is closed at a time then my perceived brightness would be double that of actual brightness?

If that is the correct formula for calculating the actual brightness of a 3D setup, there has to be a calculation for perceived brightness.

Barco Stereoscopic format comparison.

Commercial theater efficiency ratings and requirements.

Acceptable brightness is 4.5fl w/ 15% efficiency

Reald 15% efficient

Dolby 12% efficient

Xpand 18% efficient

It came complimetary with the LG 3D Bluray if you sent in proof of purchase and receipt, I ended up returning the player as it could not do frame packed with the Titan.
post #503 of 711
Basically or rather exactly you need to quadruple the light to increase the brightness to your eyes by 50%. So assuming you have 100% to start and your 3D methodolgy eats up 84% to your eyes it should look a little less than 50% as bright.

Mark:

I am sorry but the light drop off is not that significant, don't know if its the CE4 glasses but I know what I am seeing with triple flash.

The DPI Titan is by far the best projector I have owned to date. Thank you Peter Cineramax for making everything happen....

I completely agree. I have not owned a better projector!

Hopefully I wont have to own a better one anytime soon
post #507 of 711
Lon. I am not saying that it isn`t the best projector at all. What I am saying that if the light drops off by 75% it will look to ones eyes like a 50% loss.The drop off caused by a drop of 84% which is consistent with all shutter glass technology that doesn`t uses such tricks as overlapping RGB to goose light output in 3D, will give you your observations that in 3D the picture is about 50% dimmer. Masuing would show a 84% drop off but not to ones eyes.

Really no big deal given the high light output of your projector in 2D.

What this means regardless of the particular shutter glass projector, ones picture will not look 84% dimmer.

This is significant because we will see 3D shutter glass projectors in the $10k class perhaps only putting out 1200 lumens from the present 1000 lumens do to heat issues and the desire not to lower on offs. Pbliction of the 84% loss could scare some off and it shouldn`t. That said we are going to see tricks to boost light output in 3D such as overlapping RGB which has some adverse effects.

Once again, though you don`t need me to tell you, you have a great 2D and 3D projector and Peter is the man.

No not yet, I expect them tommorow, you will be the first to know

I ended up ordering 6 pairs from the bay, 1 for $30, 4 for $40, and 1 for $50, call it the sporting event party pack
