Hello,
I have successfully connected two monitors to my graphics card (Nvidia Geforce GTX 560 Ti). The card has 1 vga, 2*DVI and 1 HDMI port. I have converted both DVI ports to VGA, using adapter because all monitors have VGA ports. First monitor is connected to default cards VGA port, second and third monitors to DVI ports using DVI to VGA adapters.
Problem is with the DVI port monitors. If 2nd and 3rd monitors are connected together at the same time then they don't give display, although individually they work fine in conjunction with the default cards VGA port resulting in giving 2 displays.
My first question is why I can't get third display to work? Secondly, if I convert HDMI port to VGA using HDMI to VGA adapter will I be able to get the third display? And my last question, in the worst case scenario, how can I bridge my primary display adapter with the graphics card to get multiple display monitors.
I have GIGABYTE board with AMD FX-9590 CPU.

Thank you

It is considered 'premium' support - so no matter what kind of connection your monitor has, you will be able to connect it without adapters.
You don't need any kind of 'bridge' or anything like that to run that 3rd monitor from iGPU. Just change iGPU setting in BIOS to 'enabled' (on any other setting it won't turn on with GPU), connect monitor to iGPU and that's it. At least that's how it works with intel CPU, not sure about AMD, but why it would be different.

That's correct, but then why are there so many other ports? for e.g, 1 vga, 2 dvi, 1 hdmi? Is there any way to bridge the motherboard's vga with the graphics card for extra support?
