Can't Adjust Screen Brightness - Windows 11

Anonymous

Hi,

I noticed a few days ago that HDR is now a menu option under "Display" on my laptop, and once going into this option there is no toggle to turn it off.

Under "Display Capabilities" both HDR Video Streaming and Use HDR are showing "not supported" so I'm not sure why I even have HDR installed.

I also noticed the "adjust screen brightness" option under "Display" is completely gone, and using the Function keys on my laptop to adjust the brightness no longer works. Why is this?

I have checked all display drivers and they are all up to date. I have also have all Windows 11 updates that are available.

Will I ever have access to adjust my brightness? Seems weird the option came with the computer and seems to have now been disabled by Windows.

    Hi Dave,

    Thank you for your assistance.

    Not sure if it was the missing drivers or not, but I right clicked on the display driver in "Device Manager", clicked "Enable" and now it's back to normal!

    Appreciate your help!

    Thank you for the screenshots, your AMD graphics drivers are not installed correctly.

    Below is the support page for your laptop on the Lenovo website, from there, download and re-install the version of AMD graphics drivers they provide.
