Vizio Smart TVs don't come with a built-in internet browser like traditional web browsers. Instead, they rely on pre-installed apps and streaming platforms. To browse the internet, you can use screen mirroring or casting from a smartphone, tablet, or computer via Apple AirPlay, Chromecast, or the Vizio SmartCast app. Alternatively, connecting a streaming device like Roku, Amazon Fire Stick, or a web-enabled media player can provide browser functionality.
