Can't Rotate Monitor Bug (Yosemite)

[movierelics]

I've got a triple monitor setup. The first two monitors are horizontal 1080 displays and the third is a old dell 20" monitor turned vertical for portrait display. When I go into Displays and tell the third monitor to display at 270, all three monitors are going to that mode and there is no way to get just the third monitor to rotate.

Is anyone else having this issue?

Can't Rotate Monitor Bug (Yosemite) - FIXED

Incase anyone else is having this issue. It's an easy fix. When you tell the monitor to rotate, Yosemite wants to default to "Mirror Displays" in the Arrangement tab. Just uncheck that and then arrange the monitors as you want and things will work again.
