Recently, I remembered that I have an older monitor which I could use to have dual monitors. Since it didn't work I had it fixed and now it's working fine.

I went to BIOS, enabled integrated graphics, enabled the "surround view" option, which is (how the option is described in the BIOS) supposed to be multiple monitors option, connected the monitor to onboard VGA and...nothing.

I only get the "No signal" on the screen and that's it, not that the cable isn't connected just that it's not getting any signal.

I tried switching the cable, still nothing, the monitor isn't even SHOWING in the DEVICE Manager, but integrated GPU is. I then tried connecting my primary monitor to that VGA and I tried it with both cables and even the primary monitor wasn't getting any signal.

Now, here's the thing; the older monitor has only one port, and it's the VGA, my dedicated graphics card has no VGA, for whatever reason, that's why I went for the integrated graphics.

Some time AGO, I had a VGA to DVI adapter and while this older monitor was working, but powering on slowly, I connected it through the adapter to dedicated GPU and it said that the signal wasn't supported, so I pretty much gave up immediately, since the monitor was on the verge of death then.

I was SEARCHING the Internet for a solution for my problem, and I found out that dedicated GPU and integrated GPU don't work together but I never found out how do I make them work together.

Motherboard is BIOSTAR 6+ A960D+V3
Monitor is Acer G195HQVUsing the integrated GPU and the dedicated GPU together is very hit and miss if it works at all, as you are finding.
The bios has an option to set the integrated GPU as the primary controller but with the monitor being VGA and the performance hit you will take by using this setting is it worth while? You would be better either to only use 1 monitor. Or replacing the Acer VGA monitor with a monitor  supported by the Dedicated GPU.   It doesn't work at all unless it's supported...
Approx 8% of MBoards support it...what board is this ?
