[SOLVED] If I have a game mirrored on 2 monitors, will it hurt fps?

[jack.h.tierney]

So here is how my setup runs, plugged into my PC I have 3 1080p monitors so I can play in 5760x1080. But then I have an HDMI cable running through the walls from my office to living room so I can play on my 58" tv as well. I have the big screen mirroring the middle monitor on the triple setup. So when I play on the big screen, the game is also playing on the middle monitor in my office. The reason I do this is so when I'm in my office my mouse can't run off on a monitor that's in another room. Does this hurt performance cause the image is displayed on two different screens?

No. Sending the same image to 2 outputs is no extra work for a gpu.
