Does anyone know how to fix this lighting/brightness issue with my laptop?

Midnott

I am not sure how it happened just one day i logged on my laptop and it was like this, changing my brightness makes the whole screen dimmer or brighter but that one bit is always brighter. pretty sure its not a hardware issue. I managed to fix it last time this happened but I don't remember how i did it and have failed to do it again. Does anyone know how to fix this?

If you don't have this app forget about it. Consider restoring your system to an earlier point, type Create a restore point in the Search bar and click on System restore at the top of that window.

If it was me, I would bring the laptop to Acer Services to check your screen, maybe a bad cable/connection. Screens will lose its original brightness and may have lighter corners after some time due to wear but that takes 5-6 years, but the brightness control is indicating a panel issue.

Go to Settings >Personalization > Themes and change the background to the default Light Bloom NOT the Darrk Bloom settings as its been changed for your PC, see caption below

i tried that as you suggested but my screen is still lighter in one area like someone is shining a torch from below and darker in other. I went into settings and got into themes changing it to background light bloom but it didnt help.

Turn off adaptive brightness control in Windows:

Select the Start button, and then enter settings. Select Settings > System > Display.

In Display settings, select Brightness, then clear the Help improve battery by optimizing the content shown and brightness check box. You can select the check box to turn this back on any time.

Check this too:

Check your GPU consoles (Intel, etc.) if there is adaptive brightness control, disable that.

In Quick Access there is a Blue Light filter that dims, turn that off.

Windows has Night Light feature that dims too, turn that off (Notification area, right end Taskbar, or type Night Light in the Search bar).

I dont know how to check my GPU consoles, or much about GPU at all. I tried the rest tho and that didn’t help.
