Can I use Ivy Bridge integrated graphics and a discrete video card in tandem with the H77 chipset?

hbarnwheeler 952 October 8, 2012 at 11:32 AM
I haven't been able to find a straight answer to this question so I am hoping someone might be able to share his/her experiences in this regard. I am going to build an Ivy Bridge machine soon (probably with the H77 chipset) and would like to drive three monitors. I have a discrete GPU that I would like to pair with the Ivy Bridge integrated GPU in order to accomplish this, but I haven't been able to determine whether or not this will work.

That's good to know. Thanks.
Now to see if that works on most other mobos or if it's a special feature on yours.
ASUS is the only manufacturer I looked into that explicitly said it wouldn't work. Gigabyte said it would via email and Asrock and MSI talk explicitly about this functionality in the manuals of the boards I looked at.

Hi I am about to buy a asus p8z77 lk board, trying to do the same, ie use intel onboard graphics simultaneously with an nvidia gt430 that i own.

I see in the asrock docs they have the Surround Display feature, which I uess is exactly what we are trying to do. can I confirm:

1. What you mean by the fact that Asus is saying their z77 or h77 would not support this. Is this a specific limitation of their BIOS, as compared to ASrock. Is that what makes the differnce?

2. Does this surround display feature mean that 3570k graphics are enabled simultaneously with a video card's. or does the mobo have some other graphics capability that i'm not aware of.

I would have thought Asus would have a similar capability to this "surround display feature"? but maybe not????

Thanks much for your clarification

1) Asus tech support told me over chat that this would not work, but they wouldn't say why. I suspected they didn't know what they were talking about, but didn't want to risk the money on an Asus board, in case they were correct. I brought the issue up on an Asus support forum and got into a back-and-forth with a guy who insisted it *couldn't* work. I disagreed, and eventually, he proved me right by getting it to work on an Asus Z77 board he had.

2) The 3570k graphics are used in tandem with the discrete GPU.

For what it's worth, it worked for me with very little effort (i.e. install the card, boot, and go) and the experience is absolutely seamless.

Edit: One more thing, you probably want to build the machine and install the OS without the dedicated GPU first, and add it after.

Thanks, I did manage to talk to a techie at Asus in Texas today, and he did confirm that the multiple monitor setup/ and simultaneous onboard graphics (igpu) and PCI graphics cards will work out of the box with any of their boards, i.e. up to 2 monitors on the main board (Ivy bridge supports 3 but 2 have to be displayport, and no boards have that), and the rest on PCI cards. He said nothing to change in BIOS, although Gigabyte in their manuals talk about changing the shared memory for VGA setting? under "Surround Display Feature" and that it shouldn't be left on auto, but i don't know about that.

The rec. was to install the PCI card once the mobo was working and everything up to date (newbie tip) and Win 7 should detect all monitors after that whether connected to PCI or mobo.

Since i have 1 never used GT 430 lying around and don`t want to get another card, this will (should) work fine for my first build. THis card, the p8Z77-V Lk, seems to offer the most bang for the buck, using 3570k
