if you are here reading this post, most likely you have tried upgrading your good 5-year old asus N61 to windows 10, and was treated with a BLACK DARK BLANK screen? the problem is we are now treated with a generic AMD-ATI driver, instead of an ASUS customised one.
the generic driver is indeed working. the “trick” is to up your display brightness (Fn+F6), and you should find your LCD suddenly comes on!
took me 2 roll back to Windows 7 and reinstallation of Windows 10 in one day to confirm the above. happy windows 10-ing (:
