So i have managed to install LION on my system
ASUS N71JQ, i7 740QM, Radeon HD 5730, 4GB RAM with all drivers functioning properly from Audio, wifi, USB 2.0 and 3.0, Bluetooth, SD Card reader, HDMI, touchpad etc.
The only problem i have is that i have a black screen on my internal monitor if graphics is enabled, whereas i get full graphics on external monitors straight up to 1080p with acceleration.
Anyone knows how to solve this problem contact me please.
HERE IS A TUTORIAL AND DRIVERS I HAVE USED.
