I just got a Saphire DP-DVI singlelink active adapter. but can't get it to work in windows. The monitor does power on during parts of the boot process so the adapter itself appears to be good, however if I have it attached when the windows login screen appears my system just constantly flashes the monitors on and off until I unplug it. Once I do that I can get into windows without problem but still can't use the adapter.
When I try to enable it using the windows screen resolution utility it silently fails. Screens cycle on and off and then I get a 15 second change countdown but the monitor itself remains off, remains in the disabled screen portion of the layout dialog, and it continues to indicate that I must click apply before making any changes; just like beforehand.
I've also tried enabling it using CCC, and it thinks the monitor is on and windows will let me drag dialogs off the edge of the last working screen and onto it but it remains dark.
I'm using a 5870 with two NEC 2090's and a 3090. One of the 2090's is on the DP port, the second 2090 and the 3090 are on DVI. I'm using Catalyst 10.8 at the moment because I can't get 10.9 to install.
