I want to hook up 2 monitors to my system, currently I'm only using one monitor connected via DVI through my GPU. I have a VGA(sad face) connector behind my motherboard and I found an old monitor basically only capable of running through VGA. I've connected them both up, my main monitor is connected to my GPU and the other is via the motherboard VGA connector, but it's not working no signal is received. Can I run both the integrated graphics and the GPU at the same time without any adapters?

Most motherboards disable the onboard graphics when an external graphics card is detected. In most cases, there is no way to enable the embedded graphics with a external GPU installed.

Your best bet is to drive both monitors off of the graphics card, if that isn't possible, you will most likely have to replace the graphics card.

This post and the accepted answer might make it a little clearer why from a technical perspective.

To summarize the post, essentially the same PCIe lanes are used by the IGP and the graphics card, it is one or the other, but not both, with few exceptions.

I figured it out by myself after reading a dozen of retarded answers from people all proclaiming that they have knowledge, and know what they are talking about. They all said no it cannot be done, but one guy posted this:

Running on an Asus Motherboard, Go to Bios -> Advanced -> System Agent Configuration -> Enable both integrated graphics and GPU -> set PCIE as main controller -> exit -> reboot.

I followed it and it worked.

Lesson to take from this: Don't answer if you don't know the answer, otherwise, you're just spreading garbage.
