    Cannot change brightness after updating to Windows 8.1

    I recently got an Asus X550LA and updated to Windows 8.1, since then I cannot change the brightness level. In the settings charm the brightness charm says unavailable.

    I found posts similar to this, and none of the suggested solutions have not worked.

    I've tried:
    • Switching to Microsoft Basic Display Adapter
    • Downgraded to another version of 10.x
    • Downgraded to 9.x
    • Uninstalled and re-installed the drivers
    • Disable graphic driver and re-enabled

    None of these solutions have worked. Is there something else I should try?

    So I got it to work, it turns it TeamViewer was the culprit. Under Monitor, it was using PnP-Monitor provided by TeamViewer instead of the Generic PnP Monitor provided by Microsoft. I switched to Generic PnP Monitor by going to 'Properties -> Driver (Select Tab) -> Update Driver -> Browse my computer for driver software -> Let me pick from a list of device drivers on my computer -> Generic PnP Monitor (Select it).
    Or you can go into TeamViewer options -> Advance -> Scroll down to Advance network settings -> Uninstall the monitor driver
