    I recently upgraded to Windows 8.1 on my Lenovo Ideapad and noticed my screen brightness wasn't as bright as it had been when I had run Windows 8. I keep trying to adjust my screen brightness, but no matter how low or high I set it, my screen's brightness remains at what I would imagine a 50% brightness would be. Can anyone help me?

    Hi,

    Please try to update or reinstall the display driver for a test.

    Open Device Manager, scroll down to display adapters, right click, choose update the driver software or choose uninstall, then restart your computer.

    Regards,

    Yolanda

    Hi Yolanda,

    I had the same issue with my Samsung 7 Series laptop after upgrading to W8.1, and the proposed solutions did not solve the problem. Any other suggestion?

    Hi, Kasper

    Have you tried to manually set the brightness in the right-side charm bar “Settings” to adjust the brightness? And  can you manually adjust the brightness with the key on your Laptop?

    I also doubt that there might be some sort of incompatibility between the display driver and your computer, please check if there is a suitable driver from the manufacture website of Samsung. Or you can contact Samsung, check if they have an appropriate display driver for win 8.1.

    Regards,

    Yolanda

    Same problem here. On an HP laptop.

    Mine is way to low. It is as if the display is off. Looks like a bug in Windows 8.1 rather than the display drivers.

    Instead of asking each customer to reinstall their driver, it might be worthwhile if Microsoft have a look at their display/graphics system. Apparently, Windows 8.1 is setting it to very low values. And there doesn't seem to be any way for user to control the brightness.

    BTW, I have set the charm bar brightness to max. It doesn't make any difference.

    This doesn't work. It is clearly a windows bug. I have reinstalled drivers, installed old versions, reinstalled the new one... Windows isn't having it. 

    Please propose a real solution.

    I dont see a solution.   Updating and re-installing drivers does not. work.

    Also I am sick of you blaming others for the problems with the update you asked us to install. 

    This makes no sense.  If you guys want us to install your BS updates please make sure they won't fuck up my whole work session. 

    Please fix this asap. 

    this is necessary!

    Some good news for Samsung users.  Use the Samsung SW Update facility.  I just did.  Right now there is an update for the graphics driver and it fixes the Windows 8.1 brightness (actually dullness) bug.  Full marks to Samsung, I am relieved, I can see my screen again.  Best of luck to the non-Samsung users, maybe try your manufacturer's website.  It's quite probable that the hardware manufacturers have resolved this ahead of Microsoft.........

    I had the same problem with my P400. I was able to fix mine by going to the Lenovo website and installed the older version of the video driver. Here is a link to the drivers. http://support.lenovo.com/en_US/downloads/default.page?selector=expand. You might have to select your laptop model to bring you to the driver page. I used Version: 9.17.10.2932 of the Display and Video Graphics section. When asked if I wanted to install the driver even though the current one was newer, I selected yes. After the older version was installed the problem was fixed. Hopefully this helps

    Did you even read the original post? The problem is not that the OP can't get to the location for adjusting screen brightness, the problem is that once there, the option doesn't work.
