Basically I just built my first PC with an A4-6300 processor, a gigabyte GA-F2A68HM-HD2 motherboard, a 500 watt psu and I'm thinking of putting in a nvidia750ti but that's not important basically I can't get into bios via hdmi, so wondering for that motherboard or a gigabyte motherboard what's the main default display setting so like vga, dvi to show the bios on screen thank you
