I'm having trouble figuring out how to enable my Intel integrated graphics alongside my GTX 480 in order to use Quick Sync for stream encoding. I'm using a 3570k and a P8H77-V LE, which have Intel Integrated 4000 and support integrated graphics, respectively. However, only my GTX 480 shows up in the Windows Device Manager, which I assume is because the motherboard automatically disables the integrated graphics when there's a discrete card in the system. I've looked through the BIOS settings and haven't found anything that looks like an option (I've seen several threads mention looking for iGPU Multi Monitor or something like that) to enable integrated graphics at all times, so am I out of luck or is there another way?

I don't think I understood half the words you're using, but I know that this software exists:

http://lucidlogix.com/products/virtu-mvp-2-0-for-window...

It allows both the discrete graphics card and the integrated card to run at the same time.

Be warned though: it's not compatible with all games, and I stopped using it because it crashed a few of my games.

Sorry, I was quite tired while writing that. Pretty much, Intel has a technology called Quick Sync that allows you to use your integrated graphics for video encoding. This is useful for livestreaming, as it results in a much lower performance hit than normal CPU encoding. I'm trying to get it to work on my desktop, but the integrated graphics aren't showing up as a display adapter in Windows, and you can't exactly use something that Windows doesn't see. My guess is that my motherboard automatically turns off the integrated graphics when there's a graphics card, and I was wondering if there was a way to turn it back on since I was unable to find anything like that in the BIOS.

Turns out that there was an "Enable iGPU" option in the BIOS, just buried very deep in some menu.
