Thank you for a great question on our SmartCast™ E48-D0, and a comparison with our D48-D0!
Our E48-D0 is a unit with our all-new VIZIO SmartCast™ platform, and can accept content as Casted from your up-to-date iOS or Android smartphone or tablet. It can accept hundreds of applications, like Netflix, Hulu Plus, VUDU, Spotify, HBO NOW, and more!
Our D48-D0 is a unit with our VIA Plus platform, and has all applications built in to the TV directly. You're able to access many apps such as Netflix, Hulu Plus, Amazon Instant Video, and VUDU, just to name a few.
This is the only main difference between these models other than a slight weight difference of about 1lb.
If you have any questions or concerns, we encourage you to reach out to our Support team at 844.254.8088. Thanks again and have a great day! -Collin
