You can also use a command-line tool called cscreen:

# install homebrew if you don't have it already
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

# install cscreen
brew install --cask cscreen

# list displays
cscreen -l

output:

DisplayID  Index     Depth     Width     Height  Refresh
       1       1        32      1440        900    60
       2       2        32      1920       1080    60
use -h to display all usage options

Note:

• The first time you try to open the cscreen the os will not allow it because it isn't signed.
• You have to go to Security & Privacy in System Preferences and allow it.
