Display Clone Performance Cost? (Noob Question)

post #1 of 4
Thread Starter 
What's the general performance cost of cloning a display? let's say 1080p games?

When you clone a display do you need twice the horsepower so it runs the same as if it were just pushing a single 1080p display?

There should only be a slight drop in performance, all the computer has to do differently is output the same thing to two displays adding a bit of latency/performance drop. But this should be only a few percent loss.
