Triple displays using more then 1 type of graphics card?

[windin]

Hi there

 

ok bit of a strange one and probably a no go but I have done some searching around and not found anyone thats even tried it so i thought i would ask

 

I am running dual monitors from a GeForce 8400GS, the card is enabled using and EFI string in the com.apple.boot.plist and every things is working with no issues

 

However I have the built in Intel GMA950 on the motherboard I am using (an Asrock 2Core1333DVI-2.66G) thats sat there doing nothing, looking in the System Profiler its picked up fine but when i plug a third monitor into it the system freezes and all the new display shows is a blue screen. If you then reboot all the screens come on but but they system is totally frozen.

 

So can you get 3 monitors from two different cards in OSX? Any help is massively appreciated

 

I am running 10.5.4 from Iatkos 4.1i

 

this is what i get in system profiler

Thanks for that Peach

 

I have given it a go but no luck

 

using the instructions I managed to get the the device paths for the adapters

 

PciRoot(0x0)/Pci(0x2,0x0) for the GMA950 and PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0) for the 8400GS

 

I then put them in a merged plist like so

however when I put that in my com.apple.boot.plist repair permissions and reboot I get

 

 

I am going to carry on playing with it but its not looking good for doing this with integrated graphics and a PCIe card, I may just have to go and buy a another card for a matched pair

[peach-os]

sorry - I´ve been reading too fast and didn´t notice that you are using an onboard graphics.

that might be a problem. only things you still could try is playing with different plists that you could find and change the priority of the graphics cards in bios (if this option exists on your mainboard it´s something like PEG1,PEG2).

another mistake you´re doing: if you want more help you should attach your specs

[windin]

yeah I have only been here 2 years it takes time to get round to these things lol

 

have tried that no good so far, I have however found a PCI (yes PCI nor PCIe) version of the 8400GS I am thinking of trying with that

 

anyways cheers for the help
