So I got this 55" HiSense Android TV and something periodically puts text in the upper right corner which seems to try to categorize what's showing? It's always wrong and it even seems like it might interfere with the sound for a second. Any idea what it might be and how to turn it off?

For example, right now I'm using it as a display for a Chromebook and it just said something about Sports Series or something. It's always wrong and it's kind of annoying.

Other times, we'll be watching the Sopranos on PLEX and it'll say something about Serial Comedy or something. Any ideas?

Thanks in advance.
