Updating the TV firmware is pretty easy and is mostly automatic.
The firmware for Vizio TV and other electronics is is a computer program that is "embedded" in a hardware device and is an essential part of the hardware.
It is sometimes called embedded software.
An example is a microcontroller, a part of the microprocessor that tells the microprocessor what actions to take.
Firmware is typically code that performs configuration and control of hardware components that make up a platform.
As such, firmware is usually the first code that runs when a device is powered on, and therefore provides the foundation from which trust in the system is built.
Firmware is installed directly onto a piece of hardware during manufacturing.
It is used to run user programs on the device and can be thought of as the software that enables hardware to run.
Firmware is the foundation of the software stack that computer hardware uses for basic operations and to run applications.
Like your smartphone, your smart TV also has firmware.
