Default Re: Quadview possibe? (Quadro NVS 420)

Ok, that makes sense! I didn't know this was the case. This makes me think I can setup some custom modelines for doing 2x 1920x2400 instead of 2x 3840x1200 which would work better for my setup as well.

Just knowing that this is the case is all I needed as by default I can only get 25 Hz at 3840x2400 so I was already doing some wacky stuff b4 to get 33 Hz by completely ignoring EDID, IE:

 Modeline "1920x2400" 164.999 1920 1936 1968 2032 2400 2401 2404 2409 -hsync +vsync

    Option "DPI" "75 x 75"
    Option "ExactModeTimingsDVI" "true"
    Option "UseEDID" "FALSE"
    Option "ModeValidation" "AllowNon60HzDFPModes, NoEdidModes, NoEdidDFPMaxSizeCheck, NoVertRefreshCheck, NoHorizSyncCheck, NoMaxSizeCheck, NoDFPNativeResolutionCheck"
    Option     "TwinView"
    Option     "NoTwinViewXineramaInfo" "1"
    Option     "MetaModes"  "1920x2400,1920x2400; 1920x1200,NULL; 1600x1200,NULL; 1600x1200, 1600x1200; 1280x1024, 1280x1024; 1280x1024 , NULL; 1024x768, 1024x768; 1024x768, NULL; 800x600,800x600; 800x600, NULL; 640x480, 640x480; 640x480, NULL"
    Option     "TwinViewOrientation"      "RightOf"
    Option      "ConnectedMonitor" "DFP-0, DFP-1"
Do you know how smart the triplehead2go is with modes? Will it pretty much take any mode I give it and just divide the horizontal resolution by 1, 2, or 3, depending on how many displays are hooked up or will it actually be smart to divide it vertically if say the height is higher than the width? IE whatever is higher (width or height) it divides the input either horizontally or vertically?
