Important: Google no longer provides software updates for these third-party Smart Displays: Lenovo Smart Display (7″, 8″ & 10″), JBL Link View and LG Xboom AI ThinQ WK9 Smart Display. This could impact the quality of video calls and meetings.

You can make Google Duo calls on all Google Home and Nest devices, but a small note on a recent update to the support pages on Google’s site suggests that third-party smart displays from Lenovo, JBL, and LG will no longer be supported. As Google moves towards integrating AI into Android-based systems, the likelihood is that all other technologies, and services will eventually be deprecated to make room.
