It is a Vizio Series E55U 55" 4K smartTV home theater. I emailed Vizio about it and they told me you have to download their app and pair your I phone and use the I phone for a remote. This is so stupid. They have all the controls turned off and very little color on the picture. We only have one I phone so if one of us goes out I guess the other one is out of luck. Also the 50" same TV has a regular remote. Sometimes technology is not a good thing.
