    I have replaced original panel with excellent AUO14ED B156HW01 V4 panel. It works with no any problem. Then I bought even better glossy version AUO17ED B156HW01 V7- it works good, picture is best ever I seen on some notebook, but I have problem. It is not possible to change screen brightness on windows 7 (btw it works on xp and ubuntu). I have tried all I know- reinstall OS, change Nvidia driver, QButtons, but simply NO option for change brightness in power options or mobility center.
    What is issue- is it that os not recognizing panel* how it than working on XPS 15 Dell...
    Any solution- thanks...

    I can't believe nobody has this situation and no any experience about this issue...
