A:Answer Hi JoJo! There are three major differences between the TU7000 and the TU8000. First, the TU8000 features voice control capabilities using Bixby, Google, or Alexa. The TU8000 also features extra connections with 3 HDMI, instead of two, while adding a set of composite (Yellow, White, Red) connections. Finally, the TU8000 adds Ambient Mode taking your QLED TV screen from black to color like a screensaver, blending it in with your TV wall design when your TV isn’t in use. ^Tim
