Hello All,

My brightness key control is broken for a long time.
Id like to know if there is a fix to solve it on Mac OS Catalina:

Plz see below my screen properties:

DisplayProductID" = 0x717

DisplayVendorID" = 0x756e6b6e

DisplayProductID dec 1815

DisplayVendorID dec 1970170734

Thx a lot in advance for your help.
