The TV is 1080p but is dependent on what information you are giving it. I have a digital antenna hooked up and the signal I get is normally 1080i, only a slight difference from 1080p but still rather sharp. I have a Blu-ray player hooked up and all my movies show up at 1080p. If you are using a standard dvd player then it would display in 720p because that is the max resolution of a dvd. My XBOX ONE display goes from 1080p to 900p depending on what I am watching (Netflix, Hulu, YouTube ect) and the same for games, many only display 900p but I would be hard pressed to tell the difference when playing.
I would ask what devices you are using, or were you referring to the "Smart" features of the TV?
Hopes this helps a little.
