LG 32UN880-B cannot switch input source

[lilipeipei]

I have tried with LG alt ON, but still not working.

Though I know LG has some different DDC implementation, ddcutil does have a solution in issue discussion which works for me on Windows PC: rockowitz/ddcutil#100 (comment)

While this solution uses NVAPI, not sure if BetterDisplay could adopt this solution to Mac.

Sorry, that issue is caused by my dock.

I tested without dock, which is working perfectly.
