Hey on my Elitebook 8540w Notebook I have the problem of an undected internal Display...

I found some old information, that manual injections of NVCAP information may help at those cases...

I already extracted my graphic cards rom under windows an extracted the NVCAP value wich is 0400000000000700000000000000000700000000
with NVCAP maker und Mac OS X using my external display wich works perfect with full accelration.

Now my question, how can I inject this information? I only found instructions with some old graphic enabling kexts... isnt there a way with graphics enabler=yes or something?

Thank you!

Hey,

I am running a HP Elitebook 8540 with NVIDIA Quadro 1800M and a Full HD 10bit per Channel Dreamcolor Display. It seems to be attached via an internal Display Port.

I am trying to get my internal Display to work since years now.
My Mac OS is running pretty fine, just updated to Mountain Lion, but the internal Screen is still black. If I attach an external Display it is recognized immediately and has full acceleration. Even CUDA works perfect. So the Graphics driver seems to run nice.

I had the same problems in Linux but they where suddenly gone as NVidia released a new Driver.

I once tried to force the right detection of the display via EDID Overrides, but this should not work, because no display is detected at all (not even something wrong).

Has anybody of you experience with a similar problem? could there be a solution with DSDT patching?
If yes i could need help with that, I never got my DSDT compiled right ...

Thanks in advance...
