Looked through the wiki
Updated MonitorControl to the latest version (if applicable)

Describe the bug

The application correctly recognized both attached LG displays but both the brightness controls update the same display.

Steps to reproduce

!. change brightness on both monitors....only one display is updated.

Expected behavior

I would assume that the controls for each monitor would update that respective monitor.

Anything else?

This might be an issue related to display identification. This is a complex issue and won't address it in MonitorControl 4. Recommend switching to BetterDisplay where a number of display identification methods are available to configure which might help with multiple identical display issues.
