The above article lists all the LGA 1155 motherboards which "Allows using built-in GPU" also known as Integrated GPU / iGPU. But basically it is talking about the Integrated GPU which comes with the Intel Sandy Bridge and Ivy Bridge microprocessors. As you can see, (except for the lone exception P67), all motherboards support using iGPU along with a Dedicated GPU card.
It basically allows using the Integrated GPU along with a Dedicated GPU like Nvidia or ATI.
Using my MSI H67 Motherboard, and Windows 7 was able to successfully make a multi-monitor set up (with Extended mode, so we can get more work done faster): One monitor was connected to the VGA output on the Nvidia GT 520 GPU. The other monitor was connected to the VGA output on the motherboard (Core i3 - integrated graphics).
The same multi-monitor setup unfortunately fails in Fedora.

I know some of you will suggest getting a new monitor, or getting a Convertor to convert DVI to VGA or HDMI to VGA. But that's not the point, which is that Fedora is not keeping with the technological improvements.
Er, using multiple video adapters simultaneously is hardly some kind of new technological improvement. It's been possible for years, probably decades.
X actually used to support it somewhat 'better' prior to RandR 1.2 being developed. The new randr stuff focused on supporting multiple outputs from a single adapter _really well_, and it certainly did/does that, but it compromised on multiple adapter support as a trade-in. I'm never quite sure what the current status is on putting multiple adapter support back in, but I expect ajax or airlied would know. It may well be the case that you actually could get it to work and you just need a custom config.
