How do I show brightness of both displays

Dear Kimberley Alfonso

Thanks for posting your question in the Microsoft Q&A Forum.   I understand you're looking for a way to easily show and adjust the brightness of both of your displays simultaneously in Windows 10 or Windows 11.

To tailor this further, could you share: What is Windows version (Go to Setting > System > About)?

In the meantime, you can consider trying my suggestions for Windows 11 as the newest Windows version and please let me know anything news from it:

• Go to Settings > System > Display > Under Select a display to view or change its settings, choose each display (e.g., Display 1 or 2). If available, adjust the Brightness slider under Brightness and color.
• In Settings > System > Display > HDR (or Display > Night light), ensure HDR is disabled if it’s causing inconsistent brightness across displays. Turn off Night light to prevent color/brightness shift.
