Hi! I have geforce GTX 670 and i want to use 3 monitors i use 2 on the geforce and one on the motherboard, but it only show the monitor that i have connected to the motherboard
Go into your BIOS settings, and under video output you should be able to select either output to both iGPU and PCIe GPU or force both GPU's, something along those lines.
I have 2 27" monitors, and a 22" plugged into my 670 I use 2 DVI and one HDMI port. Your card should have all three ports as well, along with a Mini Displayport.
Once all are plugged into the card, you should be able to go into the Nvidia control panel and setup the monitors in there for with you want as Primary and then the others.
