Hello Eric_G1,
Thank you for your response.
I am using the external display as an extended display.
On the external display the Dock appears at the bottom if I set it to appear at the bottom. If I set the position to right or left, it does not appear at all at any edge of the external display. Only on my MacBooks display.
When I set the external display to be the main display and the MacBook display to be the extended display the Dock only shows on my external display.
So either way it only ever shows on the main display and never on the extended display.
It only shows on the main display at the left/right edge when holding/pushing the cursor there.
The article does not mention any settings about the Dock. FYI: I connected the external display via HDMI, it gets recognized by MacOS correctly.
Cheers!
