Hey guys,

Having a weird issue whenever I try and change the drivers i use for my 6970's in CF.

If I install 10.12 then install 10.12a over the top of it, the screen brightness is fine. This is the only properly working configuration.

If I install 10.12a directly after a driver clean, the screen brightness on all 3 of my screens drops incredibly low. Same thing happens if i install the 11.1a beta from a fresh clean out.

If I install 10.12 then go to 11.1a, screen brightness drops. If i go from 10.12a to 11.1a, screen brightness drops again.

A fresh install of Windows did not fix the issue.

The best way to describe what I'm talking about it turn the brightness of you phone/laptop up to max (normal brightness), then turn it all the way down (low brightness after a driver install). The difference is clearly visible, and no amount of color correction can fix it. This affects all 3 of my monitors.

Any ideas? Thanks.

Nvm, fixed the issue by doing a Restore Factory Defaults in CCC.
