Screen Brightness

I used to have the Driver 16.12.2 for my R7 260X , today i decided to update it to many newer versions , basically any that came after that one, and my screen brightness or gamma or whatever is insanely high , i've got a small work a round ( switching pixel format or turning gpu scaling on and off again) but i want it to be completely fixed, and no i can't get the same brightness/gamma etc via my monitor settings.
