Multiple monitors using outputs from GPU and motherboard?

[trentls]

I have been using my computer with two screens for a while, but I just found an old monitor in storage and I want to hook it up to the system so that I can have three. My graphics card (Radeon HD 6670) has one HDMI output, one VGA output and one DVI output. I've got the two monitors that're already hooked up are using the HDMI and the VGA. The problem is, I don't a DVI cable for the third monitor.

This leads me to my real question. Is it possible to have two monitors hooked up to my graphics card and a third hooked up to my motherboard? My CPU is the AMD A-10 5800k with integrated AMD graphics.

(I know I could just go down to Radio Shack and buy a DVI cable, but i'm only fourteen and i don't want to spend my hard earned allowance on extremely overpriced $30 cables or adapters)

Thanks,
Trent L.S. 😀

As long as the onboard video is enabled(may need to enable it in the bios), then YES you can use the onboard and dedicated at the same time.

Can I get some guidance on how to do that? I'm not very experienced in the bios.

First you can check the device manager(devmgmt.msc from start search or run) to see if the onboard card is actually already running. It will be under Display Adapters.

What board do you have? Most times you hit the DEL key on POST(Power On Self Test). You may need to hit the key multiple times.

Once in the bios, check under onboard devices this varies from board to board).

Let us know what board it is and we may be better able to walk you through it.

This is an image of the bios on my board and what it looks like with both cards running in windows.

First of all, I don't have the option for "System Agent Configuration" in my BIOS. I have the ASUS F2A55-M LK PLUS.

I went out and bought a DVI (single link) cable to that I could hook all of my monitors to the graphics card. I have them all connected but windows will only let me display to two of them at once. It can be any two but only two. know what to do about that?

unfortunately, the AMD card you have requires ONE of the 3 screens to be connected by DisplayPort or an Active DisplayPort Adapter.

I would not expect a System Agent section for your system because that is an Intel thing. Give me a sec to look at your board.

If you still wish to try to use the onboard video, You will need to go under

Advanced -> NB Configuration -> Primary Video Device -> Enabled

Primary Video Device -> PCIE

Integrated Graphics -> Force

The should let you use the onboard and dedicated together. You will not want to game on the onboard for clear reasons . Most other things should not be a problem for it.

I did all of this:
"Advanced -> NB Configuration -> Primary Video Device -> Enabled

Primary Video Device -> PCIE

Integrated Graphics -> Force"

Didn't work. Still only displaying to the monitors connected to my discrete card. My onboard graphics doesn't show up in the device manager either. I'm rebooting to see if i did something incorrectly, but I dont think I did.

IGFX Multi-Monitor -> Enabled, for some reason i posted Primary Video Device 2 times.

The first should have been "IGFX Multi-Monitor -> Enabled"

I saw that you made that error but i knew what you meant.
IGFX Multi-Monitor is enabled and everything, but my third monitor just doesn't have an input still.

And the card is not showing in the device manger. Very strange.

Some use the manual is when things do not work the way it is written.

I tried to hook one of my three monitors to the motherboard to.
Using this guide I enabled the IGN Multi-monitor option.
Initialy the onboard grafics didn't show up in the device manager, then i right clicked on the display adapters option and selected scan for hardware changes and it showed up.
Now my 3 monitors are connected with no problem.
hope this helpes

I think I might've found another solution that either wasn't posted here or I must've missed it but I had to manually download the VGA drivers for my motherboard (Gigabyte GA-M68MT-S2). I have already installed all of the drivers for my motherboard with the disc it came with but either that driver didn't download correctly or it was simply missing from the disc.
