VGA port on motherboard but not GPU

Consumer-grade motherboards w/a VGA port are usually just there for the output from a CPU with integrated graphics. You have selected the i5-4440 as your CPU, and it has Intel HD Graphics 4600. So the VGA port on the m/b would output from it.

You have also selected a dedicated graphics card (R9 270x), so usually that means the integrated graphics is disabled in favor of the dedicated graphics. If you don't have any ports on your current monitor compatible with the ports on your graphics card, you can usually get adapters to convert to the right format you need. So if you only have a VGA connector on your current monitor, all you need is a converter from DVI to VGA (might be included with your graphics card).
 


Just make sure you connect it to the DVI-I port on your GPU as DVI-D does not have the analog connections which VGA uses.
