Turning on/off intergrated graphics

[Kouk]

Hey everyone, i have a weird question, hopefully solvable. I have a dual monitor setup but i lack a second (DP) cable for my GTX 970 so i have one HDMI in the card and one HDMI in the motherboard. my question has two parts. First, when i play games, does having the second display with onboard graphics on decreases performance and if so how much could that be ( my CPU is i5 6600 and when i play games i have little to no apps running in the background ). And second is there a way, to turn off the display with the onboard when gaming with the discrete one ? Thanks in advance.

1. no

2. IDK.. likely not. Why anyway?

1. Not by much, probably less then when you use your discrete to drive both

2. If you're smart enough you can code your own solution
