Hi,

I just tried to hack the kext AppleIntelFrambufferCapri.kext so I could have the 3440x1440 resolution on my new LG 34UC97 (I have a Macbook Air 2012 13" Intel HD 4000) the problem is that after modifying the kext now my graphics are all messed up, there is no recognition of external screen in my laptop, I tried to install the backed up kext but its not working.

If I format my Hard Drive and install El Capitan, would I have the original kexts?? Or how can I solve this problem because its driving me crazy.

And second, could anyone can help me achieving the 3440 x 1440 resolution on this screen. I have a Hp Laptop with windows 10, that I used for work purposes with the same graphic card Intel HD 4000 and when I connect it to this monitor I have the full native resolution. How is that posible? Is it just a problem of the configuration of the card or what?

Could anyone can help me!!!! I would really apreciate it.

Cheers
Alex
