Hey gang, I have an asus p8b75-m motherboard and I would like to enable the onboard graphics card to use for dual display in conjunction with my video card, a GTX 650. My CPU is an i5 3330. Is this possible? Thanks.

You should just have to plug in one monitor to the card and one to the mobo. You may need to enable igpu multi monitor. I have seen a situation with another asus mobo that you had to install virtu for it to run the igpu. Although on my asrock z68 I do not have to.

Thanks for your reply, unfortunately I'm not sure how to enable the igpu multi monitor...and there is no option in my bios to turn my integrated graphics card back on, I can't even see it in my device manager.

If I can't see it in my bios, am I hooped?

There is no option to turn it on or off. You won't see it in device manager without it being on. The multi monitor option is in bios: advanced>system agent config>graphics config.

thanks again for your help guys, this seems to be working. When dual-display is enabled, will I still experience graphical slowdowns in games even if the monitor is turned off? Cheers

You shouldn't have graphical slowdowns but turning off the monitor makes no difference. Other than unplugging, the gpu still sees a monitor and outputs to it.

Thanks, that's good news. I'm actually having trouble finding a way to enable duplicate displays - I get the following options when I open up my control panel and navigate to my display settings:

-Extend these displays
-Show desktop only on 1
-Show desktop only on 2

No desktop duplication available :( 

Please help me, Hobbes! Cheers.

You can't duplicate over different gpus. Why did you even want to run the igpu?

Nuts. Well I have back problems and sometimes watch movies lying down, my monitor is suspended at a 90 degree angle. It should be fine though, I just need to change the display to monitor two before I switch.

Thanks for your help

Just didn't want to get an adapter to put both on the 650?
