After updating display drivers past 13.12 Catalyst my second monitor will boot up into post screen > Windows logo, then blank (signal not detected). I have a 27" Benq GW2760s (DVI / HDMI cable) and an older Viewsonic 22" LCD (DVI / DVI cable). The Benq is connected to the HDMI port on card and Viewsonic is connected to DVI port. Everything works flawlessly while using Catalyst 13.12 drivers.
After updating I can enter safe mode and both monitors will post to windows, BUT they are mirrored and windows only detects the Viewsonic monitor, so I cannot extend, etc. I have used Display Driver Uninstaller while in Safe Mode, then restart and install the selected AMD drivers, I have tried multiple different drivers after 13.12 but they all give me the same problem. I just tried installing 15.7 drivers 5 times and gave up and installed 13.12 again so I can use my second monitor.
Anyone have a clue?
