Can I watch Netflix on UE40KU6400
delbert_christiansen
over 1 year ago
If your smart TV is listed as such in the technical specifications, it should have the ability to connect to the internet and run streaming apps like Netflix. However, it is always a good idea to double-check that the TV has a Netflix app or that Netflix is listed as a supported app on the manufacturer's website or in the TV's manual.
