Right now my PC's VGA is disabled, I am using a single monitor and I am getting signal via DVI (DVI to VGA Cable) hooked up to my one monitor. I want to use dual monitors, but as of now I only have a VGA Cable. IS there somehow I can enable the VGA while leaving the DVI on so I can use the two monitors at once? And if so, how do I do this? Pleas explain, thank you!!

My PC:

CPU: i5-3570K @3.40GHz

RAM: Corsair XMS 3 16gb 1600Mhz

GPU: NVIDIA GeForce GTX 670 FTW Edition

MOBO: Asus P8Z77-V LE PLUS

Power Supply: Corsair TX650M

If they're fed of the onboard graphics, the iGPU (much slower) does all the work.

Are you sure neither of your screens has a DVI input?

Right now I am using one screen, I have a DVI to VGA Adapter coming out of the PC leading to my monitor plugged into a VGA port. What I'm saying is, I want to use another monitor but I don't have a DVI Adapter, or Cable for my other screen, only a VGA Cable. Put when I plug my VGA Cable from my PC to my monitor, it doesn't get any signal, so im assuming it is disabled. What I want to know is can I have both dvi and vga enabled at the same time, and how? For my graphics I have the NVIDIA GeForce GTX 670 FTW Edition.

If you're trying to plug the second screen into the onboard graphics on your motherboard, that's disabled when a dedicated GPU is installed.

Your GPU only has a DVI-I port, because there's basically no recent screens without DVI, HDMI, or Displayport. Are you sure none of your screens have any of those?

Both of my screens have a DVI, but I was just asking this because I don't have another DVI to VGA or DVI Cable (Only have one for the one monitor, therefore cannot use the second monitor). So I was just asking so I know if I had to buy a DVI cable or adapter for sure.

on the asus motherboards it easy to turn on the ipgpu. go into the bios under advance mode. go to priamy dispaly. by default it was set to ipgpu.
if you set to to peg or pci leave it as it is. under that line is one called muilt monitor and the next is rendering. turn both of them on and reboot.
when you get into windows it may load older intel gpu driver. you have to go to intel and download the newest ipgpu driver.

If I do this, will my GTX 670 then be disabled and it will be using the onboard GPU?

nope i have a sabertooth with a nvidia card. as log ans you leave the primany display set to peg/pci the vnidia card will be the main video output and the intel ipgpu will run the second monitor.

However, unless you deal with the Lucid side of things (do boards still come with that, or has it gone out of fashion?), it will perform far slower and not use your 670 on that screen.

I've tried that, but it didn't work.

For the iGPU memory, there was no "Auto" option. AS far as the Render Display I did forget to disable that, is that why it isn't working, or is there some other cause?

**EDIT** I disabled the render display, still no luck. The second screen is still getting no signal.

make sure under primany dispay you change it from auto to peg/pci to make the gpu your main output then the ipgpu should come on. if the ipgpu is on it show up under device manager.

Thank you it worked. I had to install the Intel drivers because apparently there were none installed. Also, how can I make sure that my primary screen is my GTX 670, and my secondary is running or the iGPU?

Where you plug the cables in.

I'm still worried that someone is using VGA in 2013, though.

Thank you for the help guys. And @Someone Somewhere, I don't have a monitor that goes above 1080p, so there isn't a need for DMI.

DMI? The link between the CPU and Chipset has nothing to do with this (but yes, you do need it).

If you mean DVI, then digital video is much less susceptible to noise and colour shifts than analog.

in the bios set the primany display to ped/pci that make the ipgpu the second output.
