LG UltraFine External Display with MacBook Big Sur 11.6 Cannot Adjust Screen Brightness
Just upgraded to Big Sur 11.6. Before this I could adjust the brightness separately on the MacBook and external Screens. Now the Brightness Scroll bar on the Display control panel has no effect and there is no check box to turn off "Automatically Adjust Brightness" but when I open the System Report on About this Mac, it says it is turned on:
LG UltraFine:
Resolution: 4096 x 2304
UI Looks like: 2048 x 1152 @ 60.00Hz
Framebuffer Depth: 30-Bit Colour (ARGB2101010)
Display Serial Number: 803NTFA55515
Mirror: Off
Online: Yes
Rotation: Supported
Automatically Adjust Brightness: Yes
Connection Type: Thunderbolt/DisplayPort
How do I adjust the brightness on the external monitor because the default setting is too bright?
