Dear Acer,

Please fix this problem, because it is very annoying. When i did set up in the bios, laptop use only Nvidia GPU, the brightness of the display is not adjustable.
It is always max. brightness. Under optimus it is not problem at all.

Thank you!

    Check the Nvidia community this brightness issue can happen after a GPU driver update and to fix it you have to roll back to an early version of the Nvidia GPU driver till the bug is fixed by Nvidia. You can also try to uninstall the dGPU driver with DDU in safe Mode, go online, reboot and let Windows reinstall the best driver. https://www.intel.com/content/www/us/en/support/articles/000091878/graphics.html

    Thank you for your suggestion. I tried to install the new Nvidia driver . I used the DDU. Doesn't helped, the problem still existed. Then i went back to officional nvida display driver from Acer website.

  • Was the problem resolved by installing the nvidia driver? What is the bios version?
