You can open a window that displays a second view of the Library. This second window displays the photos that are selected in the Library module, and uses the Library module view options that are specified in the primary Lightroom Classic CC window for Grid and Loupe view. The second window can stay open regardless of which module you’re working in, so it’s easy to view and select different photos at any time. If you have a second monitor connected to the computer that runs Lightroom Classic CC, you can display the second window on that screen.
When working with multiple windows, Lightroom Classic CC applies commands and edits to the photo or photos that are selected in the main application window regardless of what is selected in the second window. To apply a command to one or more selected photos in the second window, right-click (Windows) or Control-click (Mac OS) the selected photos in Grid, Compare, or Survey view in the second window and choose a command.
Resize thumbnails by dragging the Thumbnails slider and filter photos using the Library Filter bar. See Find photos using the Library Filter bar.
Choose Normal, Live, or Locked. Normal displays the most-selected photo from the primary window. Live displays the photo that is under the pointer in the Filmstrip or Grid view in the primary window. Locked displays the selected photo even if you choose a different photo in the primary window. In all Loupe modes in the second window, you can adjust the zoom level.
You can lock any photo by right-clicking (Windows) or Control-clicking (Mac OS) it in the main window and choosing Lock To Second Monitor. Or select the photo and press Ctrl+Shift+Enter (Windows) or Command+Shift+Return (Mac OS). The photo that is currently locked to the second monitor displays a second-window badge in the Filmstrip and in the thumbnail in Grid view of the main window.
