    Matrox Triple Head not recognized!!

    I´ve had a problem with my matrox triple heads, I usually use two to output 6 screens, this usually works fine, a couple of months ago my computer didn´t recognize one of them, that is the display options didn´t list the "spanned" modes (2400x600, 3072x768, etc) but only listed 4:3 and 16:9 modes, the other screen was detected by the computer without problem, so I was able to use only four screens, my show required six so I did everything to fix it, restart, shut down and power on, booting the computer erasing PRAM, nothing worked, I ended up using my secondary system which is exactly the same as the primary, a couple of days after that, I booted up the computer and "voila" it detected the screens perfectly, I can only conclude it fixed itself, because I didn´t do anything special to it.

    Two days ago, same thing happened, it hasn´t fixed itself yet.

    What to do????
    anyone with this same problem??

    thanx

    With X1900 you can only output 6 Screens in a resolution of 800 x 600
    So if you select 3072x768 on the first TH2G the other TH2G won´t be able to output a triple screen because it exceeds the "canvas" of the graphics card.

    A good help when having problems with TH2Gs is to disconnect the MacPro from the mains and not only put it in shutdown for a reset - that helped me in situations where I thought the TH2G was gone for good...

    It also is a good idea to do the setuo with 2 TH2Gs with a second computer via remote desktop or screensharing... - makes life so much easier...

    its possible that an apple operation system update might have changed or altered supported resolutions -

    i cannot get 6 outputs from my triple heads on leopard.

    basically there is nothing i can do about any of this - if it works - it works - if its doesnt then the graphics card and driver dont like it.

    Right after Apple released the graphics update, I was able to hack a core graphics library to make two TH2G devices work. It ran 6x1024x768 but was useless for anything else but Catalyst. I finally re-imaged the disk as it was nothing more than an experiment that had no promising results.

    Incidentally, the core video and core graphics will work just fine. The problem has to do with limitations in the way Quartz renders on the specific GPU. This is something rumored to be fixed (accounted for actually) with the release of snow leopard.

    yes - it normally works at 2400x600- 60HZ-

    it doesnt seem to work at 1024x768 - 75Hz-

    there didnt seem to be a way to do 75Hz ... with the TH2G resolutions available.
    so its not that much use in europe-


    also my performance testing has shown some restrictions with content sizes and overall graphics throughput.

    30Hz needs more ooooomph, more frames per second need to be rendered.

    Some one said he can get 3x 1024x768 out of the Xt1900 , with my system I never had that working

    the systems listed before it never run 6 x 1024x768
