Does duplicate display affect performance?

If the screens both show the same thing, your GPU renders each frame once and just outputs it to both screens — no effect on performance at all really. If you have separate views on each screen in a game, the GPU has to render the view for each, which does increase the load.

Does dual display affect performance?

Some dual screen combinations, especially with high refresh rates, prevent GPUs from clocking down to minimal power state when idling at desktop. This doesn’t affect gaming, but might have a bit of influence on power bill and idle noise level. Gaming performance is unaffected at large.

Does mirroring displays affect performance?

Mirroring is affecting performance just enough to drop your frame rate below 60 FPS. Even if you would otherwise get 59 FPS, Vertical Synchronization would drop your frame rate to 30 FPS. This may also result in input lag.
