A:AnswerThis HDTV does not support HBO Now. Alternatively, you could use Google's Chromecast in conjunction with an Android or iOS phone that has HBO Now installed.

A:AnswerI don't know if you can download more, but mine came loaded with all things Yahoo, Netflix, Amazon, iHeart Radio, Twitter, Youtube, Facebook, Flickr, and vudu (movies or something).
A:AnswerThe Vizio is a better quality TV. The lag and motion blur is less and it also supports 4:4:4 for sharper text when used with a computer or video game console. The smart TV aspects of the Sharp Roku will be superior over the Vizio. But, it's better to get an external Roku so you can upgrade it.
