sukualam Posted January 6, 2012 Share Posted January 6, 2012 please help me. how to fix blackscreen. this is happen when i install the kexts (ATI4600Controller.kext , ATIRadeonX2000.kext, and so-on) from other forums thread for my (ATI) xfx 4650 for enable full resolution and qe/ci. but when i install it, my monitor goes no signal. my pci id is (0x9498) or (0x94981002). and i already add this dev id to these kexts. My Monitor is acer p166hql (max res: 1366x768). when i rebuild kext cache , fix permission for /S/L/E . and so-on then i restart to apply changes. but after boot, my lcd goes blank "No Signal". Others forums suggest to use dvi. why must use dvi ? i dont know why must dvi. and i dont have dvi cable/adaptor. i just use VGA cable. Can it work ? Thank you.
