Hi @Viola11,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are dealing with brightness adjustment issues after a Windows update can be frustrating. 

Here are a few steps you can take to resolve this problem:

1. Update Display Drivers

The update might have affected your display drivers. Updating them can often resolve brightness issues.

Open Device Manager:

• Press Win + X and select Device Manager.

Update Display Adapter:

• Expand Display adapters.
• Right-click your display adapter and select Update driver.
• Choose Search automatically for updated driver software.

Restart Your Computer:

• Restart your PC to see if the brightness adjustment works.

2. Roll Back Display Drivers

If updating the drivers doesn't help, rolling back to a previous version might.

Open Device Manager:

• Press Win + X and select Device Manager.

Roll Back Driver:

• Expand Display adapters.
• Right-click your display adapter and select Properties.
• Go to the Driver tab and click Roll Back Driver if the option is available.

Restart Your Computer:

• Restart your PC to apply the changes.

3. Check Power Options

Sometimes, power settings can affect brightness control.

Open Power Options:

• Press Win + X and select Power Options.

Change Plan Settings:

• Select Change plan settings next to your selected power plan.

Change Advanced Power Settings:

• Click on Change advanced power settings.
• Expand Display and then Enable adaptive brightness.
• Set both On battery and Plugged in to Off.

4. Use Windows Troubleshooter

Windows 11 has a built-in troubleshooter that can help fix display issues.

Open Settings:

• Press Win + I to open Settings.

Navigate to Troubleshoot:

• Go to System > Troubleshoot > Other troubleshooters.

Run the Troubleshooter:

• Find Power and click Run.

5. Check for Windows Updates

Ensure all Windows updates are installed as sometimes subsequent updates fix issues caused by earlier ones.

Open Settings:

• Press Win + I to open Settings.

Check for Updates:

• Go to Windows Update and click Check for updates.

I hope this helps. 

Take care and have a good day.

Thank you so much for your swift help. 

Roll Back Display Drivers didn't work for me, as the option wasn't available to choose.

However, Update Display Adapterdid worked. Now I can finally adjust brightness. I thought will go blind!! 🙂

Massive help support and fast. THANK YOU!
