My motherboard is a M5A78L-M PLUS USB3, from ASUS. It have a port for a VGA monitor, and I have a monitor connected to it (this is the secondary monitor).
I also have a Nvidia Geforce GTX 960 video card, and it has a monitor connected to the DVI port onto it (this is the primary monitor). This video card doesn't have a VGA port, and the secondary monitor can't be plugged in this card.
When I boot Windows, everything is displayed on the Primary Monitor, and I'm not able to use the secondary monitor for anything. It's not recognized when trying to select my displays.
On Device Manager, the monitor isn't recognized at Monitors, and at Display Adapters, there's only NVIDIA Geforce GTX 960.
This doesn't work in Linux also. If it could work in both OS, it would be great, but focus here is Windows.
What can I do to use my secondary monitor along my primary monitor?
