Our TV is smart too. We plugged a USB cable into the TV directly from a laptop, and the TV acts as a second screen. Whatever we have visible on the lap top screen is also on the TV screen. Using WiFi, we can surf all we want from the TV, with a remote mouse, or just browse our files & pics on the hard drive. We can play music that way also.
This TV has voice recognition, just like cell phones, and listens in just like Alexa (Echo) does.
