Unable to detect dual monitors

Hello -


I have an AMD Radeon HD7900 series card, running on a Windows 7 64-bit system. I recently performed a series of Windows updates, as well as an update to the AMD Catalyst version 15.7.1.


Prior to the updates, I had a pair of Acer Touchscreen monitors set up for an extended desktop using DVI. After the updates, I can't get the second monitor to even be detected by Windows or the AMD Catalyst software. I have tried uninstalling AMD Catalyst 15.7.1 and replacing it with an earlier version (both 12 and 14), but that didn't work.


I'm a bit of a neophyte at advanced PC tech issues, so I'd appreciate any suggestions for how to get my 2 touchscreen monitors to work again.
