How can I rename an HDMI input that appears within the input menu screen (the menu that appears when the Input
button is pressed on the TV remote) on a Vizio E70-C3 big screen TV?
This HDMI input currently is labeled "Apple TV" since it used to be connected to an Apple TV but now I need to rename it to "HDMI 2."
How can this be done?
I have attached the manual for this TV.
