So i recently built a new rig and i tried to plug in the monitor to start installing windows, and i only have a dvi/vga monitor lying around, but it wont post when plugged into the motherboard's vga port, but it does post when i plug into my tv which has a hdmi on the gpu, and it only post on gpu, I tried to plug hdmi to motherboard still no post. So im wondering why it's like that, is it a defected io, or its like that until i install drivers? Thanks, not really good at english so please ask questions if youre confused.
