dual monitors - very slow now

Last Modified: 2016-11-23
On an optiplex 7020 with ATI Radeon R5 240 card and 2 monitors with DVI connectors (the white connectors)  running windows 7.

I have 1 white cable going into the mating connector on the video card. the 2nd white cable is going into a dell supplied DVI to displayport adapter that then connects to the other port on the video card.

When I had just the DVI in the DVI port (1 monitor), the machine was running good.  But now that I have the 2 monitors, whenever I do things, windows open slowly.  TYping now is fine.  But closing windows / opening windows, things happen slowly.  I can drag windows around across the 2 screens at normal speed.

Is there some setting I need to tweak?
