you have PC with Integrated Intel HD video card and AMD Radeon 7670m on PCI-E slot, plug that blue( usualy) monitor wire out from the integrated card and put it at AMD Radeon 7670m card, when you turn PC on, it should automaticly detect that as your default card. if no then in bios change vga boot to PCIE slot
