Nope! You don’t need an internet connection to use your XClass TV, it's recommended so you don't miss out on everything that makes your TV smart: apps, movies and shows, and certain features.
If you decide you want to connect your TV to the internet, a high-speed connection will give you the best results.
What type of high speed Internet connection do I need?
Most home broadband services work well, but you may need faster speeds or more bandwidth to watch higher quality content like in 4K or High Dynamic Range (HDR). Contact your internet service provider (ISP) to find out what’s available in your area.
