What are my camera settings for Monterey 12.2.1? I need . 720p (1280px x 720px) or higher.

Guess that will all depend on the Year of this computer .

Try check your specific Year and Model against the Apple Tech Spec page to determine the Builtin Camera Resolution

You are welcome and thank you too.

Glad to be of assistance

Do come back to the Apple Support Communities ( ASC )  in the future, if / or when additional question may arise
