Do I need a dummy plug?

[Belial88]

z77x-ud5h, i7-3770k 5ghz, sapphire 7950 dual-x L3, rosewill capstone 550m

CGminer litecoin

So I have both my monitors plugged into my igpu, and i can only mine from my gpu if I plug into my gpu, and then after starting, plug back into my igpu.

Is there any way besides a dummy plug to get around this? I get the following on cgminer -n :
