I've been having an issue lately though, since I updated Windows. I used to run Windows 10 last updated like 2 years ago. I have an AMD HD6870 and I used to be able to display 4k content with it but more importantly 1080p@120hz. This was sorking with Catalyst 15.7.1. However, after I installed all the last Windows updates, it seems like the drivers were reset (low resolution when updates were finished), so I went ahead and reinstalled the Catalyst drivers.

Once it was done, I rebooted, re-patched the drivers with this software but on reboot, I had a blank screen. After the Windows loading screen it just turns black. I tried enabling low-resolution mode and same thing happened. The only way I could fix it was by uninstalling the driver in safe mode. I then reinstalled Catalyst once back to normal, but when I tried again same thing happened.

So I really don't understand what changed with the last update... did anyone have trouble after updating Windows?

When the screen is blank, is the mouse cursor visible? If you check the monitor with CRU, do you see 3840x2160 @ 60 Hz anywhere including in extension blocks and TV resolutions? If so, delete it before patching the driver. You should be able to unpatch the driver in safe mode if it doesn't work.
