Why does only one monitor have display when using multiple monitors on my Asus G20CB Desktop?

Ensure that both monitors are powered on. During POST, only the monitor connected to the VGA port has display; the dual display function works only under Windows. When a graphics card is installed, connect the monitors to the output port on the graphics card. Check if the multiple displays settings are correct.
