Having 2 monitors displaying same image affects performance?

[masterleon40]

does having 2 monitors displaying the same image lower the performance? i want to use a vr headset and to be sure there are no problems with the image i must plug in a display cable for the vr and other one for my monitor, both would display the exact same info.

My sistem:
i3 7100
z270 hd3 gigabyte
ddr4 8gb
gtx 1050
500w evga 80plus(white)

No, it doesn't affect performance.

People use multiple monitors all of the time.

as said the performance is not affected, but do you have the REQUIRED PC SPECS to use the VR device you have in mind?
