asked on

dual monitors - very slow now

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?

I updated the drivers - although I think it was the same version.

It's only when a window opens or closes really.  It takes a second or so to open and close.

happens on both screens.

I don't deal with dual monitors much so I had to play with them a little while to get them set up - they were 'backwards' - right screen had left screen info, etc.  I swapped the cables on the back of the PC, chose 'swap' in the catalyst app a couple times, make this my main screen, etc.  took a bit of playing to get them the way they should be.  (more than I would have thought, but again, I don't do dual monitors much)
