alexoiu :
Is iGPU Multi monitor enabled in BIOS? If yes, try connecting the 3rd monitor to the motherboard and see if working this way.
I just realized that is my friends mobo that i put before. went back and found my actual one.
ASUS M5A88-V EVO AM3+ AMD 880G SATA 6Gb/s USB 3.0 HDMI ATX AMD Motherboard
judging from the fact that i cant find anything in BIOS about monitors anything, I'm going to assume its not something this one can do.
