Possible to use discrete graphics card together with onboard graphics?

post #1 of 6
Thread Starter 
Would I be able to connect another monitor to my onboard video through my motherboard?

Yes you can run a third monitor from the onboard. You need to go into the bios into the options for the onboard graphics and enabled multi monitor support. It may be called different things on different boards but if you see anything that mentions multi-monitor, lucid logic mvp, or other clues than that is the feature you need to enable.

By default if an external card is installed the integrated graphics turns off and you need to turn it back on to use lucid mvp, quicksync, or plug another monitor into it.

Shouldn't be any drivers issues I have used it many times with no problems...

You can use a discrete graphics card and the onboard graphics at the same time for multiple monitors. It works for me on my old Intel Sandy Bridge onboard graphics + AMD discrete graphics cards. smile.gif

Just so you're aware - the on-board GPU is actually disabled when you do this - only AMD with their APU processors can combine on-board and discrete GPU's using an ATi card in Crossfire. Every other situation, the on-board port is powered by the discrete card only.
APU what?

Either I did not understand what you just wrote or you are wrong. I am leaning with wrong.

By default the Intel HD graphics automatically shut off if a dedicated card is plugged in.

Lucid MVP will not function. Intel QuickSync video encoding will not function. The video out on the motherboard will not function.

You can go into the bios change one little setting and then.

Lucid MVP will function. Intel QuickSync video encoding will function. The video out on the motherboard will function along with the video output from the dedicated graphics card.

The only limitation is that you can not duplicate the video output between the 2. When I say duplicate I am speaking of the option in windows where if you have multiple monitors plugged into one video card you can have them all output the same signal. This option is missing when running one monitor off a dedicated card and one off the integrated graphics.

You really can't argue the opposite as I have done this.

Also you can make the integrated graphics work together with the dedicated/discrete graphics regardless of whether the monitor is plugged into the dGPU or iGPU. This allows for a x-fire like scenario that really doesn't do much for performance but does provide some other fairly interesting and useful features. Those features are handled by Lucid MVP.
