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?
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)
