Hi there,
well, m1ddc certainly sends the proper command - what the display does with it is entirely up to the display firmware. Not all displays support input changing properly, but LG displays generally (not always) do. It might be that number 17 does not correspond to the desired input?

@waydabber Thanks a lot for your quick response. I found I can use ControlMyMonitor on Windows to change the property of Volume and Contrast like what I can do with m1ddc on MAC Air M1. But failed to change the Input value even though the permission for this property in ControlMyMonitor is Read+Write which is like volume. The possible values of Input Select in ControlMyMonitor is showing 0,17,18,15,0. I have tested these values and got the same problem. The display will flash and back to current view. I am going to search if any new firmware for my display and post updates here.

Great, thank you! :)

(btw, I'd try input numbers from 0-32 regardless of the reported supported values, as those are not always reliable).

I also met the same problem, have you solved it?

Same issue here.
I've enumerated 0-32 and it won't switch to the other input. On some values I get the same flash to black @vwumumu was getting then back to current input.
Monitor: LG 27GL850-B connected via DP
macOS: 13.0.1 (22A400)
Going to also look into a firmware update for my monitor.
Edit: there are no firmware updates for my monitor.

For me, it didn't show the real number options. I've got a Samsung Monitor where these numbers are assigned to the ports:
- HDMI1: 5
- HDMI2: 6
- DisplayPort: 15
On Windows, I use winddcutil.exe setvcp 1 96 5
to switch input to HDMI1. (Download: https://github.com/scottaxcell/winddcutil.) Note: 96 is the decimal representation of the vcp feature number 60 hexadecimal.
@waydabber Can I use m1ddc the same way? Using set input
doesn't work here.
