I don't believe you can use the integrated GPU at the same time as a separate graphics card.
You can only switch between one or the other, if that's what you're after, or do you want to use all 4 displays at once?
Can you be more specific regarding the exact model number of the LG monitors and the make and model of the TV/monitors?
TV/monitors Hannspree ST321MNB 32" LCD TV Full HD 1080p 4 x HDMI,vga Black
6,5ms
LG LG W2261VP Full HD TFT LCD 22" HDMI.dvi,vga
I was under the impession you could utilise the grapics on the Asus P8Z68-V PRO at the same time as the discrete cards if not looks like I will have to forgo crossfire and use dvi and both hdmi on each card and utilise the catalyst suite to span the monitors ??
