Can my old iMac 2012 27" serve as second display with my new iMac 2020 27"? What adapter and cable do I need?
iMac 27″, macOS 10.15
However, in Apple Support Community, I saw the following message:

Use your iMac as a display with target display mode - Apple Support
"You can connect any of these older iMac models to another Mac from 2019 or earlier for use as an external display."
If your new computer is a 2020 iMac it can't use another iMac as a display.
Also, I checked my iMac 2020. In System Preferences -> Displays, there is no selection for "Arrangement". What should I do?
Thank you.
