Issue with brightness not updating

Question

I have had this issue for a while now but have never gotten around to actually looking for a solution. The issue is that whenever I try to update the brightness of my display the slider moves as normal however no difference to the actual displays brightness. I have tried using my hotkeys, the options in the right hand side of the task bar and even in of the Windows Mobility Centre but no update. (In of the Mobility Centre the text is greyed out but the slider still moves). The brightness only updates after I shutdown and restart my laptop. I have tried uninstalling my graphics driver and reverting back to an older version in of safe mode with no luck but any other advice would be greatly appreciated

This issue is known for about 6 months i'd say. It has to do with the NVIDIA Drivers, the last one known to work is 522.25. If you want to use any newer driver apparently the only solution is to disable NVIDIA Optimus in BIOS. But doing so drains your battery faster.

I really hope they finally get to fixing this issue since Dell just released a newer Graphics Card Driver as a safety patch, which makes me want to be stuck on 522.25 even less.

When I was using windows 10 in my pc brightness control slider not working that time. So I updated my display adapters drivers. After driver updated I can adjust my pc's brightness. SO you can use this method and update your drivers using Advanced driver updater tools.

@Lutay​ Thank you for the response. Are you able to confirm if it was an AMD Radeon Driver update or a Nivida Geforce Driver as I have downloaded both off of the Dell update and neither of which have done the job in repairing this issue.
