Can't change screen brightness

[greeny99]

I switched to windows 11 a while back but recently I lost control of the screen brightness - the slider isn't there anymore, my keyboard controls do nothing and there isn't any brightness setting in the settings.

I tried to update the display driver but HP doesn't support Windows 11.

I don't think I can switch back to windows 10 (as much as I'd like to anyway).

It is currently stuck at minimum brightness.

I've tried to find a 3rd party app that might be able to sort it but they can only dim the brightness by overlaying a "filter" - although I've looked, I'm not very tech-savvy so maybe someone else has had more luck?

I can't seem to find anyone else with this exact problem.

Any help would be really appreciated

Hi ANAND_ANDY

Thank you for your reply.

The problem, however, is not with flickering but with the brightness and the fact that I can't change it.

I think the problem started around the same time as an incremental update to windows 11. I can't update the drivers because when I go to the HP driver update site, there is no option to select drivers for windows 11 - only windows 10.

Thanks,

Henry
