@shreedt, Welcome to HP Support Community. 

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

It looks like your HP All-in-One Desktop 27-cr1064 does not have external brightness controls and relies on Windows settings. Since the brightness slider is greyed out, here are a few things you can try to fix the issue:

Update Display Drivers

Since your PC relies on the Intel or NVIDIA graphics driver, outdated or incorrect drivers can cause brightness control issues.

• Right-click on Start > Device Manager.
• Expand Display adapters.
• Right-click on your Intel UHD Graphics / NVIDIA GPU > Update driver.
• Choose Search automatically for drivers.

If this doesn’t work:

• Download the latest display driver from HP Support or from Intel/NVIDIA’s website.

Enable Generic PnP Monitor

• Open Device Manager.
• Expand Monitors.
• Right-click Generic PnP Monitor > Enable device (if disabled).
• Restart your PC.

Adjust Brightness via Intel Graphics Command Center

If your system uses Intel graphics:

• Open Intel Graphics Command Center (download it from the Microsoft Store if needed).
• Go to Display settings.
• Try adjusting brightness from there.

Change Brightness via Power Plan Settings

• Open Control Panel > Power Options.
• Click Change plan settings for your selected plan.
• Click Change advanced power settings.
• Expand Display > Enable adaptive brightness.
• Set both On battery and Plugged in to On.

Check Windows Night Light or Third-Party Apps

• Go to Settings > System > Display.
• Turn on Night light to reduce eye strain.
• Use a tool like f.lux to control screen brightness artificially.

Check HP Omen Gaming Hub (If Installed)

Some HP AIOs allow brightness control via the Omen Gaming Hub.

• Open HP Omen Gaming Hub and check for display settings.

I hope this helps. 

Take care and have a good day.
