Hi James, Thanks for your inquiry. Yes, you can use this TV without connecting to the internet and solely through HDMI cables only to watch your favorite TV shows/programs.
To get the latest software updates and the best smart features experience, you will need to connect the TV to an internet connection. If you're going to use the streaming applications, then you may need to connect it to a network. Hope this helps! Erin
