Major display issue!

[CODBOPSWAW]

So my pc runs an MSI B85-G43 mother board and a zotac gtx 780 amp edition gpu. My pc suddenyl started giving me issues in terms of what displays it wanted to work on start up. Ive got a triple monitor display. If i plug in my gpu, and plug my hdmi and vga into it, it works two of my 3 displays and then when i go to plug my third into my mb, none of the mb display ports work BUT if i take out my gpu and plug my hdmi and vga into the mb, they work. Basically: mb ports w/ gpu, dont work. /without gpu, work. Anyone know what is going on? Its so frustrating!

The motherboard display ports are disabled by default when a gpu is installed and used. Certain motherboard support multi monitors that allow you to use both the gpu and motherboard display ports by turning it on in the bios.
Check in your BIOS under settings > advanced and see if there is an option to use your integrated graphics for multi monitor.
