Disney+ is supported on Vizio SmartCast TVs, models 2016 and newer, except for models E32-D1, E32h-D1, E40-D0, E43-D2, E48-D0, E50-D1 and E55-D0.
The Disney+ app can be found in a carousel row of the "SMARTCAST" input. The Disney+ Vizio app is only available in the United States, Canada and Puerto Rico.
For the best experience, we recommend a high-speed Internet connection. (Please see this article for more details on the recommended Internet speed requirements for Disney+.)
