Great discussion. I’ve been researching monitors as well for the same reason.
A key thing I need is video capabilities for Zoom meetings, etc. That is why I love my old iMac - video camera is built right in and was so bummed out Apple did not update the 27" all in one iMac. Combo of Mac Studio and new Studio display is super expensive as already widely discussed.
The Apple Studio Display has a camera (although it has been widely criticized for less than optimal quality) but few of the others listed here have cameras built in.
What are good external cameras for those monitors that don’t have cameras built in?
