You can zoom and filter photos in Loupe View. If you click and hold the icon labeled “1,” you’ll see a similar list of options for your primary monitor.
That way, you don’t have to assign keywords to tag people in your photos manually. People is where Lightroom identifies faces in images, including new ones you add to your library.
Click and hold the monitor icon marked “1” to see these options. The other options are Grid View, Compare View, Survey View, or People View. The default for the secondary display is Loupe View, but you can change it. Then go to the monitor icons on the left side of the Filmstrip -> click the monitor icon labeled “2” to activate the secondary display. To do this, go to Window -> Secondary Display -> Show. To set up a two-monitor display, you first need to connect your second monitor and then get Lightroom to recognize the secondary display.
