Is it possible to enable Onboard Graphics along with an Integrated Graphics card?

I've been going at this all day and I'm stuck. I'm trying to connect TWO monitors to my PC. See specs below. I have a DVI-D going from my Dell LCD Monitor to my AMD Radeon Graphics card DVI-D Port and my Westinghouse LCD Monitor to my Onboard Graphics Card D-SUB Port. DVI-D Cable works on both monitors. VGA Cable works as well for both when AMD Graphics are not NOT installed.

Basically:

Dell LCD > DVI-D > AMD Radeon HD 7750

Westinghouse LCD > VGA > Onboard Graphics

I just installed the AMD Graphics card today and it seems to override the Onboard Graphics to the point that when the Card is in, the Onboard Graphics Card does not display in the Device Manager, though the AMD Card does show up.

Is it possible to enable both cards at the same time so that I may use two monitors? Or am I wasting my time?

Specs:

Dell Monitor #E198WFPv
Westinghouse Monitor #L1975NW

Lenovo PC Tower
Windows 7 Professional
Processor: Intel Core i7-3770 CPU @ 3.40GHz
Installed Memory (RAM) 16.0 GB
System Type: 64-bit Operating System
Graphics: AMD Radeon HD 7750 Graphics

Any help would be greatly appreciated.

You can't use an imbedded GPU at the same time you are using a dedicated GPU
Even if it were possible in theory your BIOS won't let you

If you can activate the on board video chip and port in BIOS, it will work. Several of my machines are capable of that, even when a slot has a graphics card plugged in. Some you can't activate.
Other ways to add monitors:
A USB to VGA or DVI or HDMI external video adapter box and software. Up to six on a system, depending on your CPU chip.
Another video card that has two or more ports for monitors.
A Matrox Dual Head2Go box for two monitors from one cable. NOT A SPLITTER!
A USB monitor and its software.
Another computer's screen, linked by local network and MaxiVistA or ZoneScreen software on both.
