If you've purchased a new smart TV in the past few years, then chances are you've at least come across TCL as a name in the market. The company offers some of the best budget smart TV options out there for many people, especially if you're looking for flagship features at affordable prices. If you do have a TCL TV, then there are a number of settings and features you can mess around with to not only personalize the TV, but also improve the picture quality. While we've already covered some of the TV settings worth changing as soon as you unbox a new TCL device, this time around, we want to focus on the features you might not know about yet. Some entries in the company's lineup use Google TV, while others rely on FireTV OS or even Android TV or Roku OS.
