The new dual screen adapter Matrox DualHead2Go
is able convert the analog VGA signal from virtual 2048x768 screen to dual analog 1024x768 displays.
http://www.matrox.com/graphics/offhome/dh2go/home.cfm
My idea is from 1 VGA output of my NV graphic card /adjusted of virtual screen 2048x768/ with 3d pageflipping stereo signal spliting of signal with DualHead2Go to 2 1024x768 signals with pageflipping stereo for 2 projectors.
Is this real possible?

Why don't you use the NVidia stereo driver package and its dual VGA output option ?

I guess you have an NV card incl. dual vga support. Normally standard.

Therefore you don't need to think about that via a matrox solution.

Problem is that only 1 monitor VGA output had on dual VGA card active pageflipping stereo (with consumer stereodrivers), second monitor had other part of horizontal spann desktop, only mono :-( and this vere possible resolving of this problem.

Are try to have a multiscreen stereo presentation?

If so, you will need a solution that includes genlocking so that the two images pageflip at the same time. I don't think what you are describing will provide this.

If not, you only need one VGA output total, which is why your nVidia card only pageflips on one output port.

Argghh... I wish this board had an edit function (yes, I did use preview, but I guess I'm blind...)

Obviously, I meant "Are you trying to have a multiscreen stereo presentation?".

Apologies for the confusion...

Hi,

I have the Matrox pherilia 128 Mb dual DVI and I want to play my 3d stereo movie through 2 LCD beamers. is this possible and how????

I can only play a movie on 1 full screen. Left or right.

Thanks

Hi Hornet!
Yes, it is possible! I am using the DualHead2Go to put pageflipped video on 2 CRT's with a combined 2048x768 resolution.

I did benchmark tests on the system using two 6800XT cards in SLI mode. The test report is on http://www.3Dflightsim.com (Includes a clumsy photo of the setup)

Benchmarks for DualHead2Go stereo

I think for months than Dual Head Matrox adapter is no compatible with good graphiccards and the software is no 3d compatible. Are the signals of CRTs totally synchronous? Have performed tests with DLP PJ s? Is this out of box solution, or is tweaking needed?

The Matrox dual head adapter is in this time compatible with most NV Graphiccards!
3D stereo on 2CRTs or DLPs is possible!

Hi Hornet!
>>You asked: 3D stereo with SLI- is this possible? >>What version of drivers is?
I am using version 92.18 NVidia drivers with the beta version 92.18 stereo driver. The stereo operated in perfect synchronization on the 2 crt diplays. However, you notice there is not any performance gain when SLI is engaged in Stereo, at least not with FS9. I expect that FSX and other future video games will gain from an SLI setup.

As to the other question: I would say the setup is an "out of the box" solution. I did not have to do much tweaking except for learning how to install the Matrox drivers and how to operate them.

I plan on using the system for 2 beamers (projectors) - but I think you would need to add a stereo projection converter to correct for reverse stereo.

The earlier driver versions do seem to operate the setup in stereo, but they do not work well when SLI is engaged. Also, 3DMark crashes when the stereo is engaged - but the stereo works very well with FS9 and Trainz 2006.

Cheers!
DualHead2Go with stereo

Hurra, wow,
Is the picture quality on CRTs OK?
Are you performed tests with beamers (1 beamer, 1CRT -pictue quality).
I will buy this Dual headadapter, is no cheap, only real possible 3D stereo on 2 beamers.(Cheapest way for 140-150 FOV sim)
SLI in this time had for 3D stereo no performace gain (drivers problem). and thx, thx. Your tests results are for my very serious. Hurra

PS:This is my setup: my setup

The maximum refresh rate for the Matrox device is 85 Hz for low-res, 60 Hz for high-res. This is O.K. for LCD monitors and 2D, not for 3D and stereoscopy ...

Hi,
for my beamer (1024x768) is 85 Hz maximal refresh, this is max refresh of dual head adaptor in res 2048x768 (for my ideal).85 Hz refresh is not ideal, for my sims aplications in dark room no so bad. And the price is cca 1/10 of another solution of 3D 2048x768 projection.

What you're saying is very true for an active display configuration, but not if you're using this for a passive (polarized) configuration. Since each monitor would be doing 60Hz (and, barring ghosting, would be giving 60Hz to each eye), that's the equivalent of an active system running at 120Hz! And an 85Hz setup would be giving you an equivalent of an active system running at 170Hz!
Of course, then you would have to deal with all the calibration requirements, brightness and crosstalk issues, etc., but it still could be a workable situation for some.

Hi, have 85 Hz DLP active system, for home use in dark room excelent, absolutly minimally flicker, in this time ideal for home use (price/benefit ratio is high). Today i tested the possibility of rendering 2048x768 85Hz stereo with NV 6600 Diamond and tests are OK, rendering is possible, the FPS with Condor soaring sim are cca 27-30or higher FPS(in stereo) this is acceptable. I will in this time waiting with purchase of new Gcard (drivers). DualHead2Go is on way (2-3 weeks).
The best Gcard NV for 3D stereo with full no problem functioning consumer 3D drivers is?

this is interresting,
what about dual-head graphicscard for passive 3d with nvidia driver, together with 2 th2go's from matrox. this could drive 6 beamers for 3 screens of passive 3d,

can anybody tell me if the matrox th2go is compattible in this way?

Maart: I undertand, you want to fork L and R outputs to multiple projectors ...
Nice idea - but useles without edge blending and the projectors overlap. We had done a lot of experiemnts to overlap projectors mounted in very precise montage withotu edge blending - it does not work. The result looks very bad primary becous of non-uniform light intensity in the edge area (this is given by the total projection geometry) ...

Michal, I know you're not a fan of dual projector passive, but the fact is that it has been a successful option for quite a long time.
Yes, there is non-uniform intensity (in all projectors-whether single or dual) and Yes, there are registration issues, but that doesn't mean the 3D effect is ruined, just that it isn't optimal.

Scott: My company had made several passive intstalation and 90% intstalation done by Lightpseed (for witch I work as well) is passive. I am jsut only a fan of the best solution for the given problem.
Nor active nor passive multi-projection do not work without edge blending. On the edges the light fall on the screen in different angle than in center. For silver screen with hig light gain it means up to 100% diference in reflected light intensity !!! The edge blending compensating for this is a total must (for both active and passive projection). Who had seen this in praxis knows what I speak about ...

I'm sorry. I do believe you know what you're talking about-when given the correct topic.
I may have confused the issue of the Original Poster, as *I* was talking NOT about multi-projector panoramic projection, where I agree there would be a need for edge blending, etc., but simple 2 projector overlapped (co-located screen image) passive projection.
While this is NEVER as sharp as single projector resolution, because of the differences in registration, etc., it is certainly very acceptable. Personally, I wouldn't fool with it in a mobile situation where one had to keep re-adjusting at every setup, but for fixed installations, it works perfectly well.
Light falloff isn't that much of a problem either, especially if you cheat and throw the image slightly wider than the screen, using the screen edges or curtain to crop the outer rim.
And I wasn't referring to extra-large screens either, just run-of-the-mill home theatre sized or small corporate audience sized screens.

I'll make myself clearer next time...

the thing is will the nvidia drivers accept the alternative resolution of 3840x1024 and will it work with the th2go? will it show strange artifacts with the matrox surround gaming settings? will the outer left and outer right screen allign in 3D to the middle monitor?


dont forget cave like displays are very expensive, but this would be "cheap" and great for hobbyists to do a homebrew semi cave setup, maybe using diy beamers.

off course it will not be perfect becuase edgeblending isn't there but, you shouldn't compare this with a proffesional cave setup. (there is also no perspective corrected 6-dof position tracking for that matter) it will still be very cool for playing games if it works. just immagine playing WOW!

the nvidia drivers supports a lot of games and so does matrox surround gaming, so this could be very cool and compatible system!

I don't know about you Michal, but I'm realy exited about the possibilities of combining this matrox hardware with Nvidia's to see if we could get best of both worlds.

greetings,
Maart

Hi
Maarten see this http://www.3dflightsim.com/tests.htm
The NV drivers are able rendering in 3D 2048x768 85Hz problemless. Matrox drivers for DualHead are compatible with all NV 3D stereo compatible cards. Matrox Triple head is problematic(60Hz refresh)Is possible installation of only 1 (dual or triple head )adapter on 1 Pc system.
Also for 3D at 85 Hz is useable only DualHead2Go (2 CRTs or 2PJ 3D stereo on 85Hz). For my (and my budget) no bad. Additional software for edge blending vere good :-)

"Is possible installation of only 1 (dual or triple head )adapter on 1 Pc system."

I've read on the matrox forum that it might be possible to use multiple th2go's, but it is not supported by matrox, as far as I know the matrox th2go just fools the graphic card that 3 monitors are actualy 1 monitor, if this is the case 2 th2go's theoreticly could be used, with nvidia dual head output to get passive 3d. (three left signals on one vga port and 3 right signals on the other vga port) this way 60 Hz per eye is no problem and since it's all horizontal liniar polarisation shouldn't be a probem.

Maybe the worst difficulty for Hornet initial idea, is to find software that can run in 2048x768. Maybe FS or some other few ones can (I don't know), but does someone know if normal FPS (Half Life 2, CoD, CoD2, FarCry, etc) or other flight sims (IL2 Forgotten Battles, Pacific Fighters, Battle of Britain 2: WoV, Falcon 4, LockOn, etc) can do it?

Hi,
have tested on my graphiccard for my the most important application = Condor soaring simulator (with declaration in drivers 1. screen TV and 2048x768 res, 2. screen CRT monitor) and FPS in 3Dstereo (4xAA!) are cca 20, no so bad have 6600 Diamond graphic. FS2004 is running on 2048x768 problemless FPS see above. I think this is no probem. Waiting for Dual head 2Go is sooo long!

In relation with the Matrox triple head, limited to 60 Hz, I wonder if it is not possible, in a n easy way, to duplicate each pair of frames so you have the same sequence and action speed, but at 120 Hz. And then project it via a three PJs (eventually DepthQ or other that was found to work at 120 Hz...), achieving a three 3D screen, and so avoiding the junction of both screens (when using only two) just in the middle of the point of view...

About the synchronisation of the glasses, I think it would not be a problem that an easy home made electronic circuit couldn't solve.

Hi,

I have been reading info on triple head at Matrox site http://www.matrox.com/graphics/offhome/th2go/tech_brief.cfm
It seems that the usual (or allowed) resolution are,

Supported resolution-----Equivalent to
3840 x 1024-------------3 x 1280 x 1024
3072 x 768--------------3 x 1024 x 768
2400 x 600--------------3 x 800 x 600
1920 x 480--------------3 x 640 x 480

According to Matrox, and if I am not wrong they say that working with the maximum res allowed (3840 x 1024) at 60 Hz the RAMDAC should have an speed of 3840x1024x60=235929600Hz=236 MHz minimum. As many RAMDACs runs at 400 MHz it would be not a problem. By the same calculation if we stay with a more "modest" resolution (i.e. 1024x768) and using the THEORETICAL max value of 400 MHz of the RAMDAC, we will find that the maximum theoretical refresh rate is (400*1e6)/(3x1024x768)=170Hz. Which is more than enough.

If I am not wrong this could mean that the triplehead maybe *could* be possible at high framerates...

Another subject is the capacity of video cards to render at enough FPS in stereo so wide frame...

Even if the calculation of the last post is not completely correct, here there is an applet of Matrox to enable expanded modes in not-matrox cards:

http://www.matrox.com/graphics/offhome/support/th2go/tmet.cfm

85 Hz is not the worst thing of the world... (I still think that maybe it could go even higher though...)

Nice pics. If I was sure about the capacity of the Gfx card to render 3072x768 in stereo at good fps, I would go for a triple head. In my opinion it is more 'natural' and I do not have the joint of both screens just in front my nose...

It is a real pity that stereo does not take any advantage of SLI or Quad-SLI systems...

Btw, have you tried to test it at 100-120 Hz (creating a new resolution mode)? I'm going to try to test it with my CRT and the soft of matrox

EDIT: How can you test these resolutions? Do you have a triplehead device already? Or your CRT allows more than 1600 pixels width? I can't reproduce your test.

Hi,
in this time I have no Matrox device ( Dualhead2Go is on way). Have dovnloaded matrox software (drivers for dual and for triple head).
Have my TV, and CRT 21"(max 1600x1200), Benq PB 6240. Have Triple head drivers installed, then config 3072x768, then TV as primary display config, and CRT as secondary. And then tested. Is little problematic, in one time this was succesfully. I think with device this vere more simplier (device give PC info of max resolution).
Are accesorry software possibilities for triple head, for games modification (see Matrox homepage for triple head2Go). This all is exciting, but Condor no modificated runn only max 2048x768, I hope for change after modifications on 3072x768.Then I can the dualhead change for triplehead (only more 2PJ s!).
Have no tested for 120Hz, the max Matrox refresh for 3072x768 (after modification for 3CRTs) is 85Hz.

Hornet, I see that you have a 6600. I guess you have 2 outputs in it. You have connected the TV to primary and CRT to secondary (and the PJ remains not connected). Right?

Yes,
can conect all 3 (TV, CRT, PJ) after config in NView only 2 are active (TV, CRT).
Interesting is that I mus the settings repeated and in one time was active 3072x768 in 3D stereodrivers. NView vere clone mode. First are active the drivers of Triple head and I have configured new 3072x768 res. I hope with device this must by simplier (autodetect).Interresant-my CRT is able to display 3072x768! The image is croped, but sharp.System detected only 1600x1200and this is normal possible 3D setting.

I don't have success. I have installed the triplehead drivers, but any software on the PC neither new options in nvidia panel appears...?

After installing triplehead software, do you have some software of matrox that you can execute?

Thank you Hornet for the kind words. I hope you
receive the Matrox DualHead soon. Here's an update
regarding the 2 projector set up:
1) The setup only works at 75 Hz refresh rate at the
2048 x 768 resolution. I believe it is
problem with the version 91.28 stereo driver.
If I solve the problem and get the panoramic
image to refresh at 85 Hertz (which should be
possible) I will post the solution.
2) It is important to have the two projector images
at exactly the same size where the two
images meet. But this is not too much
trouble. If one of the projectors is on a rollable
cart this is very handy for adjusting the images.
Good Luck! - Alan J.

Very nice layout. Thanks for posting! I wish you luck with the refresh rate. Have you tested it with previous driver versions?

The screen at the right seems tilted horizontally. Is it true or it just seems to me?

Hi, is this problem with refresh no from projectors (one from then = maximal refresh for this projector?)Have you created 2048x768x85 resolution ? (possible creating this and then reinstall drivers). With 77.77 and 3d 77.77 and my graphic have no problems in 85Hz refresh.
I so excited, dual projector 3D setup is my dream.

Hi
DualHead2Go is arrived, first tests with 2 CRT monitors are OK, on 2 displays is 3D OK at 85 Hz!My favorite Condor soaring sim had no problems with rendering in 2048x768x85 res.(FPS 27-33 good). FS 2004 is problematic becose I have maximal settings, after lowering of settings it is better. Farcry at 2048x768 is in this time no funct. (I thing little tweaking is necessary).One problem is=with Matrox drivers at 2048x768 res are the stereo screenhots deformated and no usable.
Interesting is in this res with Matrox drivers the testing picture of NV drivers is no functioning./No so big problem/.
In 3 days I wil testing dual head with 2 projectors.

Hi, after tests, here the pics,
With DualHead2Go technically all is OK, refresh 85 Hz, no desynchronisation, no picture degradation, ideally for 2projector pageflipped stereo. Condor soaring sim in 3D cca 30 or more FPSwery good. The little color change L/R is becose lamp running time difference of projectors, with eye no so visible.

News
little desynchronisations (short off of glasses)when the FPS is droping or fast movements are present can by totally removed with use of

Have no this info, theoretically with enhanced new software for 3 CRTs (at 85 Hz) this is possible (3x1024x768 85 Hz). The main problem is the compatibility of used software in this resolution and ev. deformation of picture in this resolution.
With DualH2Go is 2 projector 3d stereo absolutly problemless at 85 Hz. Absolutly no picture qality degradation or deformation. I love Dual Head!

What about using stereoscopic player (peter wimmer) with 3 dlp's (3x1024x768 85 Hz) with triple head adaptor? Did someone try it?

Hi, have tested stereoscopic player from P.Wimmmer in 2048x768 resolution, have some problems, the stereo in this resolution is no working with stereodrivers from NVidia. (Is stereoplayer tweaking necessary?)
I think upscaling to this big resolution is too expensive for normal PC.

I'm using triple head videocard (not adaptor TripleHeadGo) Matrox Parhelia for page-flipping stereo on 85 Hz (three projectors BenQ 6210, total "physical" resolution 3072x768, screen aspect ratio 4:1). There is just one difficult: StereoscopicPlayer plays "movies" with max resolution 2000x500 per eye (Parallax Player - 2400x600), therefore i'm making "widescreen" movies in resolution 2000x500 ("not widescreen" movies for one projector in "native" resolution 1024x768).


Stereoscopic "cinema" on three projectors

There are no problems with new driver and BIOS for Matrox Parhelia. I'm making "movies" in resolution 2000x500 and 15-20 fps (bitrate about 6-8 MByte/sec). The quality of picture is much better then 3D-DVD with resolution 720x240 and 30 fps :-).
