“VIZIO Model: E43U-D2 After downloading the smartcast app do you need an internet connection to use the smartcast app in order to use the tv functions such as going to settings or changing to another input input?”

• Thank you for a great question! After being paired with the SmartCast application, you do still need a network connection, as the display and your smartphone will communicate through your wireless router. Thanks again and have a great day!

• I think you do, we have not been able to get this to fully function but it has more to do with a newborn baby than the tv itself.
