How to use my Samsung Note 4 to mirror to my tv

[AC Question]

I have an MHL cable connected to my Samsung Note 4 phone and an hdmi port on my Vizio smart tv. Am not able to view anything other than satellite tv. Do I have to change any tv settings, input or what am I doing wrong. Everything I read says this is simple. NOT.

Usually I have to change my input around to get an HDMI device to display to the TV. Does your MHL adapter have a power input? I've read that Samsung devices won't do MHL output without that.
