Turn on the television. Check that your VIZIO television is connected to your home network. It doesn't matter if it's connected wirelessly or by Ethernet cable. If it is not connected, choose "Network" from your television menu options and set up the wireless network, or plug in your television to the modem with an Ethernet cord.
Navigate to Netflix from the list of apps on the television, and press "OK" on the remote.
Select "Yes," then "OK" if you currently have a Netflix account. If not, you need to sign up for Netflix before proceeding to the next step.
Note the code provided on the television, as this is the activation code to begin using your Netflix account on the television.
Turn on your computer, which likely uses the same modem as your VIZIO network connection, and enter your username and password on the Netflix website.
Enter your activation code on the Netflix activation Web page, or click on "Your Account & Help" and select the link to "Activate a Netflix Ready Device" to enter the code.
Press "Activate." Your television now accesses Netflix.
