I’ve had dual monitors for a while now and never had a problem, however, the other day, I installed a new motherboard. After booting it back up, only one monitor had turned on.
I have one monitor plugged into my graphics card, and the other plugged into the onboard slot.
The one that is turning on is the one plugged into the graphics card.
How can I get my computer to recognize the onboard monitor?
Why are you using onboard gpu if you have a 760? You will need to go to your bios though and enable the igpu, onboard graphics, whatever they have elected to call it.
