Hi. I have a Dell Optiplex 3010 running Windows 10 Professional with an AMD Radeon 7700 series graphics card installed. The card has six mini-DisplayPort outputs. We use one for the desktop, two are connected to small (19") monitors via DP to VGA to VGA converters , and two are connected to 50" Vizio TV's via DP to HDMI converters. The converters were purchased direct from Dell (an AMD distributor) after being told what to purchase by AMD Tech support. We use DisplayFusion to manage the cards.
Ever since we installed WIndows 10 we've had trouble with cloning windows. I wonder if the card is supported under Windows 10.
One related question - how does Windows and the display driver assign monitor numbers? Most of the time the desktop is monitor 5, even though it's connected the third output from the right (looking at it from the back) on the video card. One day though it decided to be #1. How is that possible?
Help would be GREATLY appreciated.
