I'm attempting to connect my AMD Radeon HD 7850 to an LED wall via the wall's controller card which receives a DVI-D connection.  Regardless of which port I connect the wall to on my card (DVI, HDMI, DP with passive DVI connector), the display doesn't show up in the Catalyst displays window even when I manually push the Detect Displays button.


The Windows however, DOES know that the device is there and if I look at my Display Devices in the device manager (or using the MonitorInfoView tool) I can see that the device shows up and shows that it supports the correct 640x480@60Hz and that its no longer connected.  

Is there a way to force the device to show up in Catalyst?

I can connect successfully to the wall with my Mac Book Pro using the same DP-DVI adpater using the default OSX display driver for its Radeon HD 6750M


OS: Windows 8.1

Card: XFX AMD Radeon HD 7850 Core Edition 


Catalyst Driver 13.152

Control Center: 2013.0830.1943.33589

Well, that's such a strange config that I bet than no one in the community has anything similar. I suggest you contact AMD instead.
