I have a Dell T3600 workstation with an SSD, running Windows 7 64bit. I decided to run 5 monitors instead of the 3 I had been using. I bought and installed a Radeon HD7750. The driver CD that came with it included drivers from 2013. I installed everything (Catalyst control center and all features). All 5 monitors were in color but I lost Aero. In trying to fix Aero, I ran the dos command 'net stop uxsms' and then 'net start uxsms'. There was no change but as I clicked exit from the Catalyst control center, everything went black and then two of my monitors were in black and white. I tried rebooting, used AMDs driver wipe tool, reinstalling from the cd but I was not able to bring them back into color. Then I downloaded the latest driver (Crimson 2016, 16.200) and installed it and now I have 4 monitors in color but one is still stuck in black and white. Aero is also back with the Crimson driver install. Any ideas?
