A:AnswerHello Ricky, this model unit is only able to set the sleep timer to power the TV off. Please contact us at 855-544-2030 so that we may further assist.
A:AnswerYes, the Shark Roku Tv can. That'was one of the first things I did, was add the Disney+ app. We have a Vizio smart TV that I haven't been able to do it on.
A:AnswerNo. It comes with a remote and the Roku device is built into this TV. When you first setup the TV it will walk you through the steps to connect to your current Roku account.
