How can I get my second monitor to run through my onboard graphics instead of the dedicated graphics card?

I have 1 monitor, a Samsung TV working fine through my AMD Radeon HD 6990 series graphics card, using a VGA to DVI cable, and another monitor, just a generic PC Monitor hooked up to my onboard graphics via a regular VGA cable. I've read a lot of threads where people have 3 monitors, 2 on the dedicated card and 1 on the onboard so I figure what I'm asking must be possible.

If I use the Samsung/DVI/Radeon it works fine, although I have no 2nd Monitor. It doesn't show up in the screen resolution page, even if I click "detect" or "identify", and it doesn't show up in the Device Manager.

If I use the PC Monitor/VGA/Onboard that works, although the Samsung stays blank. It doesn't show up on the screen resolution page, even when I click "detect/identify" HOWEVER, they both show up in the Device Manager as perfectly working.

I've gone into the BIOS screen as well, that's how I'm able to switch between Onboard and Dedicated graphics.

This is pretty frustrating as I am literally flat broke and I simply want to set up the monitor I've been saving for this exact purpose. The fact that they both show up in the device manager when I'm using onboard graphics tells me that this must be doable.

If you need any information about my setup, can you let me know how to provide it?

Thanks in advance

I too have tried doing this. Unfortunetly system crashes and decreased performance was the result. I decided to to leave them both on the same card ad eventually got another card but using the dedicated graphics along with on board hardly improved performance and was more than a headache than anything.
It is considered bad manners here to expect someone to answer you in 20 minutes...

May be the keyword here is "switch"

Some time ago, installing add-on card disabled on-board video altogether. Check your motherboard whether what you want to do is possible at all.

Last but not least - your card should have DVI interface, why you are crippling it with VGA-to-DVI adapter? You will get much better picture on your TV by using all-digital connection (DVI-DVI, or DVI-HDMI, or HDMI-HDMI).
