Ok so i just upgraded from windows 8.1 to windows 10 after the update it told me to update my display "Advanced Micro Devices, Inc. - Graphics Adapter WDDM1.1, Graphics Adapter WDDM1.3, Graphics Adapter WDDM2.0 - AMD Radeon HD 7640G" and after ive successfully updated my display started to get funky and most of the time the brightness is just the minimum, often times its on the maximum setting and i can no longer adjust my brightness I have tried everything to try and adjust my brightness after a couple hours of fiddling around i just decided to uninstall this display update but somehow just cant find any answers on how to do it so i need help.
