Can't get the input selector to work

[soype]

Hi, kind of a noob here. I've been using ddcutil in linux to find my monitor's input codes but they don't seem to work here. I have an "LG FULL HD" monitor (really, that's the name) and whenever I switch its input to HDMI 2 or HDMI 2 Lg alt, the monitor goes to the first input available which is a DVI input with nothing connected. I'm guessing that is because it doesn't find the assigned input.

How can I know which is the input code in order to make it work? I'd also like to know the HDMI 1 code in order to control both Linux and MacOS inputs from here (I'm using the same keyboard for both)

Hmm. I am not sure what could be wrong. The codes should be the same as they are in Linux, as this is display dependent, not OS dependent. Does switching work in Linux all right? The LG alt mode is for some newer displays, probably an LG FHD display with a DVI is not in this category.

I found a way to have it working using the DVI connections offered by the software. They apparently hit the spot. However, sometimes it doesn't work. Is it maybe because I'm using ddcutil in Linux as well? Maybe I should just use the shortcuts from mac?

No, but not all displays respond to commands from unselected inputs or they might do from one input but not the other, depending on how the controller board is wired.

I can't today, but tomorrow I'd be happy to share more info to address this issue as it's the closest I've gotten to changing monitor inputs without standing up. Can I DM you or email you?
