Let me try to explain. I own a Passive Dual 3D projector setup by Infitec (http://www.infitec.net/index.php/en/). The system consists of 2 Epson TW9200 projectors with both projectors containing a Infitec filter; one for the RIGHT eye and one for the LEFT eye. The projectors are controlled by a Infitec splitter (http://www.amazon.de/INFITEC-HDMI-1-.../dp/B00OFWRJPS) which has one HDMI input and 2x HDMI out (1x for LEFT projector and 1x for RIGHT projector). The problem is that it is simply undoable to get a good calibration with this setup because both projectors have it s own influence on the outcome. You cannot simply calibrate the projectors separately with a end result that is good. This can t be done because both projectors in theory should cancel out the differences they both have. In practice however the colors are just too much off. I can get the 75% color saturation ok but then the 100, 50 and 25% are WAY off for some colors. And I m talking about delta values of 15-25 here! So....... here is a flow chart how my chain runs. What I need to know is if this will work or if I have to put the Lumagen AFTER the Infitec 3D Splitter. If this is the case, then I would theoretically need TWO lumagen mini's! But maybe it will just work fine if I put the Lumagen Mini 3D BEFORE the Infitec splitter. What is important to know: The infitec splitter has an internal color correction system where Blue, Green and Red can be adjusted. By default all three are on a 100 value but because the Infitec system causes a way too Greenish tint I do have to tune down the green value to approx 70. So this means that AFTER the Lumagen Mini 3D a green correction will be made! My thought was that if I put a Lumagen Mini 3D in my setup placed before the splitter, I could adjust the green in the first place and only AFTER that let the Mini 3D do it s job (I own Chromapure so I could buy the Lumagen add-on for CP). Hope you guys can advise me and hope you understand what I m asking sanderdvd is offline Old 02-10-2015, 05:55 AM AVS Forum Special Member Join Date: Jun 2005 Location: USA Posts: 7,279 Mentioned: 30 Post(s) Tagged: 0 Thread(s) Quoted: 2650 Post(s) Liked: 2153 It seems the Infitec is a color band pass solution, so by design it is doing something differently to the color being passed through each projector. Unless someone else here has this solution, or one similar, it will be hard for anyone to answer what you should do since its impact on the approach is not comepletely known. But firstly, if its this bad, what does Infitec say? Maybe there is something wrong with your setup that needs to be fixed first. Secondly, does it matter what color modes you run on the projector? I understand this is a high light loss solution, so are they running in some vivid-esque mode to maximize brightness at the sake of color accuracy? Can you try a matching pre-calibrated/cinema mode in each projector? Even if dark, do the colors look better? Finally, Epsons usually have some decent gamma and CMS controls built in. Does the Infitec solution preclude calibrating each projector, and would it even matter if the color shift is being introduced in the splitter or filters? Does the filter get removed for 2d? Perhaps it is impossible to color correct with the filter unless they have a target they are trying to achieve that you could somehow calibrate to for each projector. At the colors equally poor after their splitter, or differingly poor? What is Infitec's guidance on the splitter's RGB controls? This sounds like something Infitec should address if the end result of their solution is poor...

You are indeed right I am looking for some hands-on experience with the system. But someone who really knows how to calibrate the setup. I have been to Amsterdam to the ISE this morning and there I spoke with 3 guys from Infitec. Of course they where not the technical guys over there but commercial persons. They had really no clue what to do with my questions. I bought the system from a dealer who had the intention to start selling the system in the Netherlands but as it turned out there is little interest for this niche product. Why did I bought the system you might ask? Well, for a 3D enteusiast like me there is simply no better solution for 3D at home then the Infitec system. If you have never been able to see the system in practise one has really not a single idea what you are missing. It is simply stunning 3D. I have had a lot 3D projectors including the SIM2 3D-S but the Infitec system just leaves them all far behind. The completely flicker- and ghostfree picture due to the Dolby 3D technique that Infitec uses gives you an incredibly ultra good 3D experience. So far about me bragging about how great the system is The filters are BUILD-IN both Epson TW9200 projectors. When switching to CINEMA mode the original Epsons filter which is used for Cinema Mode is replaced by the Infitec filters. Switching back to Living Room mode is for watching 2D on one of the two TW9200 (I switch watching 2D from time to time so both projectors have approx the same hours on the lamp so I don t get too much light output deviations). You have to understand that the Infitec system tries to 'compensate' the color errors from the left and right projector (so the left and right eye). By trying to get both projectors calibrated separately you will just loose more light then needed AND still don t end up with a good result. So somehow I do need to find out how to make this all work but hey, where do I start my investigation.......

Still considering xvYCC for 21XX and potentially 20XX, but we are not working on this currently.

thanks for your reply but this will simply not work at all. The Infitec filters (which are hardware build-in so removing them is not possible anyway ) have a very big impact on both the Greyscale and Colors. Even if I COULD calibrate it without the filters it will make no sense to do this. The filters will just completely whipe out the calibration that you did. There is one thing I m 300% sure about: the calibration needs to be done WITH the filters......

Sanderdvd - jrp is likely correct in what he is saying. You're only going to be able to calibrate succesfully in 2D mode to something like REC.709 without the filters in place.

You mention that your projector inserts the Infitec filter when you go to Cinema Mode, and removes it when using Living Room mode. With the filters in place (Cinema Mode) your color output is dramatically changed, which is part of the design of the Infitec system itself. It's similar to the Omega system which removes large areas of color energy\bands for each eye.

I've attempted what you're trying to do - getting a calibrated output with filters (Omega) in place to get a 'proper' color aligned output for each eye. This experiment failed as there is no way to magically add back in the energy\bands that were removed by the filters. You can increase your RGB levels all you want at specific points but it won't even come close to adding back in what's been removed.

Now in theory what could and should happen with these color systems is that there is a 'black box' in between your video source and dual projector output that can be calibrated and aligned to the specific projector\light output\screen combination to get you great color matching output. To my knowledge though this specific type of calibrated correction doesn't exist outside of the digital cinema world.

Considering this is an Infitec 'system' you've purchased, I'd do what thrang suggests and talk to Infitec about what can be done. If Infitec had a specific left\right 3D calibration target then maybe you could use that to address each eye, but I'd guess this is part of their IP and probably not publicly available.

jrp is not correct in his statement. I m not talking about the greyscale (RGB) adjustments here but about the color accuracy (CMS). The filters affect the colors in a very big way. You can get pretty good delta values at eg. 75% (which is the preffered color saturation to get delta values under approx. 3) but this will cause 25,50 and 100% saturation completely off. I ve tried to look for a comprimise as good as possible but I m not satisfied with the result up to this point. As you can see below the greyscale is good enough (knowing that you cannot ever get it as straight as with a simple 2D single projector calibration without filters), but the colors are just too much off.

I need some help with 3D output.. Up until now I have been solely using my Mini3D with my Projector (Panasonic AE8000) with 2D sources and not bothered with 3D. However I'd like to view Gravity in 3D, and some other 3D movies I have acquired.

Initialy my Bluray player Oppo BDP-93 would not detect my setup is capable of 3D and would display the warning message.
After adjusting some settings on my Mini3D, i.e. setting most things to AUTO.

That worked however I get intermittent issues, i.e. I use the 2nd HDMI output from my Oppo direct to the Mini3D bypassing my AVR. I get no sound, even tho the Oppo is connected to my AVR with the first HDMI output from my Oppo.

If I use the first HDMI output via the AVR, I get a white screen on the projector. Sometime the Mini3D would even lockup i.e. it wouldn't respond to remote presses.

Also a question, when playing a 3D source why can I not see the Mini3D menus, pressing Menu on the remote shows nothing onscreen (via projector) yet the movie will continue to play. Even pressing OK to show the info screen does not display. Is there a setting for this?

Does this indicate an issue with my Mini3D?

thanks

You should get the OSD on your screen when you press OK. If you do not it is likely that the ir signal is being locked by the ir emitter for the 3D glasses on your projector spraying ir throughout the room (presuming they are ir and not rf). you can check that by covering the ir receiever with your hand and putting the remote right up against the scaler. If the OSD comes on then you know where the problem lies.

On the other questions this is most likely due to settings in the scaler and Oppo. I do not have an Oppo so can't advise on possible settings you need to change
Also, if you have short hdmi cables swap them out for ones that are at least 2m long.

I respectfully disagree with you and feel that JRP is correct. Look at it this way: if your system works to provide 3D by filtering out certain wavelengths of light, wouldn't correcting the display's color output via CMS (if you could) restore those filtered frequencies and reduce or eliminate the 3D effect?

Thanks for posting the Chromapure measurement information. Were these measurements taken from behind the glasses as well? What you've posted is exactly what I expected to see - gamma is all messed up (2.74 at 50%) and green and blue are all over the place in the CMS measurements.

The CMS in your projector is likely the standard 6 point one where you get to set a specific point for each color and that's it. It's the same type as in my Panasonic projectors and most other CMS consumer displays. The Mini3D can help here in introducing 125 points of CMS and other Lumagen models offer more than that. The question is though - can these extra points in an external CMS get you a decent REC.709 output with the color altering glasses and filters in place?

In my testing with the Omega filters, glasses and Mini3D the answer to this was a no. The linearity is taken so far out of spec - relative to REC.709 which is what you are calibrating to - that it can't be corrected with the range of correction the external CMS has.

I know with the Dolby cinema box that it's supposed to be doing color correcting before the signal reaches the projectors. Presumably there is a nice workflow as well from Dolby on how to calibrate each projector to get good results. That Infitec splitter looks like a regular GeoBox to me. Have you measured your projectors output with the infitec splitter installed\removed from the chain to see if it's even doing anything to alter the video signal? It might just be splitting the HDMI output to left\right like a normal GeoBox and the only color altering might be at the filters themselves!

In my testing with the Omega filters, glasses and Mini3D the answer to this was a no. The linearity is taken so far out of spec - relative to REC.709 which is what you are calibrating to - that it can't be corrected with the range of correction the external CMS has.

I know with the Dolby cinema box that it's supposed to be doing color correcting before the signal reaches the projectors. Presumably there is a nice workflow as well from Dolby on how to calibrate each projector to get good results. That Infitec splitter looks like a regular GeoBox to me. Have you measured your projectors output with the infitec splitter installed\removed from the chain to see if it's even doing anything to alter the video signal? It might just be splitting the HDMI output to left\right like a normal GeoBox and the only color altering might be at the filters themselves!
The measurements where taken without the glasses because with the glasses I will get too inaccurate dark readings because of the reduced light. But it makes no difference to measure with or without the glasses. The filters in the glasses are exactly the same as in the projectors. The Infitec splitter is only for splitting the signal like you say. It has a color correction option but it is very basic (Blue, Red and Green can be altered from 0-100 with default all on value 100. Infitec told me to just leave them all on 100).

Can you tell me more about the Dolby color correction box? Is it available for sale and what does it actually do?

The Dolby box is a digital cinema piece of equipment that allows you to measure and calibrate each eye individually to a specific standard. Anything digital cinema related costs thousands of dollars so this would be no different. The measurement process seems to be reading Red, Blue, Green, White and light levels for each eye, then it creates an intenal LUT of some type and corrects the output for each eye from that point.

References for this:
Discussion on calibrating - http://www.film-tech.com/ubb/f16/t000875.html

We don't really know what's going on behind the scenes here in software that's creating that Dolby specific LUT. It's taking some simple measurements, but what is it calibrating it to? It sure won't be REC.709 which is what you're targeting. For the Mini3D it might indeed be able to do a 3D LUT and sort out the colors, but the calibration software is the key here in being able to know what reference you're trying to calibrate to.

Some of this work was looked at before here on AVS although what was achieved might not be the perfect left\right output you were looking for:

We'll I just got back my jvc after its second trip to mendtronix. First trip was power assembly. Second trip was to replace the case that was chipped during the return trip. Today I get it running and it won't sync with the lumagen scaler in the loop. I can run the oppo 103 directly to the jvc and run the signal through the denon, but once it enters the lumagen, it shows no signal. Any thoughts? I haven't change anything in my set up prior to sending it back to replace the case.

Thanks

You might simplify the system such that you have the JVC, the Mini and a Blueray source near each other. Use 6 to 10 foot HDMI cables.

You can also try the Mini driving a display to make sure it is working as expected.

See if you can get this working and if so, it might just be a HDMI cable issue.

In your power up sequence, have the projector come on last.

I'll try that guys. This wasn't an issue before....to compound the problem. I noticed tonight I have a vertical line that appears and reappears periodically about 1/3 for the left side. I tired several blurays and switched cables all with the same issue. The line wasn't their prior to sending I the projector in early January when they replaced the power assembly nor when I got it back. (Had to send it back a second time because the case got cracked during return shipment). So this lack of syncing and the line are new after the case was replaced. Just got it back today. I've been I this cycle of issues since January 7th.

I know my cable lengths are correct since I've read about shorter lengths in the past being an issue

I have swapped out cables and know it's not a cable issue.

I did take the unit up to our bedroom tv and yes, I am not able to get a signal with the mini in the loop. Any other ideas at this time before sending it to you for review?

I'm a little frustrated right now...not with lumagen, but with mendtronix. I sent my year old jvc in for repair first week in January. They replaced the power assembly. Once I unpacked it I noticed a large chip and crack in the case.

I sent it back three weeks ago to have them how replace the case that was damaged by them or by their carrier.

I get the projector back last night and can get it to sync with the lumagen...Plus, I now see a vertical line the height of the image about 50% of the time during playback. My wife noticed it too. It's never had this issue before the initial repair nor during the week between the power assembly and sending it back to replace the case

An update. I again switched out hdmi cables with the bedroom tv and did a reboot. I was able to get an image.

I took the lumagen back down to the HT room. I have it in the loop again....OPPO 103 to denon 4100 out to mini to JVC. I am now able to get the menu on the screen, which I wasn't able to yesterday. I still can not see an source image. The info page shows picks no source/signal on the input side. I've tried both input 1 and 2 and still doesn't pick up the source signal (tried several source component and cables).

Thoughts?

Jim: No need. I've been able to get the JVC to sync with the lumagen. Not sure what the issue is with the JVC, but I'm talking with the lab techs at Mendtronix and documenting the issues. thanks for the offer to consult over the phone.

Interesting problem when installing the Mini3D… If I use my Darbee at the same time, I can't use it after the Mini, simply can't get the projector to find a signal… if I use it before the Mini, then everything is working fine.

I don't think this is a problem though… both of these should be able to do their job regardless of the order the signal travels. Right? :-)

Funny...I just bought a Mini3D last week. I have no trouble running my Darbee after the Mini. Everything works great. On the other hand, when I run the Darbee before the Mini3D, I get connection issues when I watch 3D movies. So I run the Darbee after the Mini3D and all is well.
