Intel hd4000 Stopped displaying

2 posts in this topic

Recommended Posts

Hey guys,

 

I have an alienware m14xr2 with a 1366x768 lcd and an intelhd4000. I had the intel hd4000 working perfectly with the the 1366x768 original lcd that came with the laptop. I wanted to upgrade my screen to a 900P screen (1600x900). I checked both my OSX and Win7 partitions before installing the lcd and they both loaded fine. I installed the lcd into the laptop and booted into windows 7 to verify it worked fine before putting the laptop together. I verified the resolution also and windows 7 was using 1600x900. Then i tried to boot into OSX (10.8.3) and it went to the chameleon screen, then apple screen popped up. After the pinwheel stopped spinning the screen flickered and went blank. I know the system is booted because i can hear the volume changer dinging.

 

I have also tried all the efi strings for the intel hd4000 by creating copies of my chameleon.boot.plist file and loading it through boot flags when i launch my osx system.

 

Does anyone have any ideas as to why this is happening? I also cant boot into safe mode, the screen is still blank. I was thinking of removing the intelhd4000 kexts but was looking for any other suggestions before doing that.

 

Thanks in advance,

 

 

These are the strings i tried.
