Hey guys, I've got a HP 530 laptop with intel gma 950 (0x27a2 device ID) and it runs SL flawlessly
The only problem I've got is that I can only get image through the monitour out, I insalled the kext for my graphic card but in the laptop monitor all I can see is a grey screen, it works perfectly except for that
Any ideas?
Thanks in advance!

So you may have to remove the video kext as it is not working.
There are several methods for it including correct kexts, string injection and DSDT. Some got lucky just by adding correct device ID to .plist.

Hi, at your external monitor set your resolution at 60hz shut down remove
ext,vga cable reboot done......
