    Unable to change my laptop's screen's brightness and connect to my second monitor.


    I've tried uninstalling and re-installing all my Display Adapter drivers and also all the Monitor's drivers within device manager with no success. I've also updated my Windows to the latest version there is and that hasn't changed anything. Any advice would be appreciated.

    :)

  2. Unable to Change Screen Brightness of Laptop


    So I'm not sure how long this has been happening but for some reason, I can't change the brightness on my laptop screen. I have linked a picture and as you can see, my brightness says 0% and that I can't change it, however my actual brightness is at 100%. I have looked around everywhere and the only responses I have found don't work for me. Here's a list of everything I have tried:
    - Reinstalling Display Drivers
    - Rolling Back Display Drivers
    - Reset Settings on UWT4
    - Power and Battery Settings
    (UWT4 or Ultimate Windows Tweaker 4 is a customizer for Windows 10 and I thought that might be the problem but it wasn't)

    If anyone has any suggestions on how to fix this, it's greatly appreciated! Thanks! -

  3. monitor brightness?

    Hi Tom,

    To change your Windows 10 monitor brightness, we suggest that you follow the steps below:

    • Click the Windows logo; then, search for Control Panel.
    • Select Hardware and Sound.
    • Choose Power Options.
    • On the next screen you should see brightness slider at the bottom of the Control Panel window.

    We would appreciate it if you could get back to us and provide us your feedback.

    Laptop Screen Brightness is not the same as Secondary Monitor's brightness

    After I installed windows 10, I noticed that the screen brightness on my laptop's screen was dimmer than the brightness of my secondary monitor. Not dim enough to suggest a problem with the lamp, but just dim enough to be annoying, as though it was turned
    down in the settings. I went through and tried to change the screen brightness, but it failed to be effected. Is there anything I can do to fix it?
