Could not load Displays preference pane

[PG Studio]

Hi Guys,

I just installed Sierra using Clover without any problem.
I'm using and HD 4000 (Z77m-D3h mobo) + ATI Radeon HD 6xxx (3 displays setup). The display seems to be ok but i cannot load the preference pane.
If I disable Intel Injection, i can load the pref pane but, of course, i don't have any acceleration and the resolution is {censored}.
I see that some guys are having this problem too but most of them are on laptops which is not my case.

Thanks!!
