3rd Monitor poor performance

Hi,I am running 2 Acer 27" displays from my MacbookPro. The first display is hooked up to Display 1 via Displayport connection. This display works great. The second display is connected via HDMI. It has choppy response and trails are visible in Word. When I move a window, it is jumpy and it is difficult to put it in a specific place. I move this display back and forth between display 2 and 3 and it does not change anything. I have the refresh rate set at 60 Hertz. Any ideas?
