A:AnswerThanks for your interest. The USB port on the VIZIO Home Theater Display is designed for firmware updates. Various files may or may not work in the USB port, as it is not designed to be a media reader. Thanks! -Randal
A:AnswerThe TV does not support Bluetooth but external audio devices can be connected to the TV through the optical audio, RCA audio out or through an HDMI Audio Return Channel setup. Thanks! -Randal
A:AnswerARC stands for audio return channel. Its used to send sound to and from the receiver.. So a sound system plugged into the tv with hdmi getting sound from a different system. Like a DVR or a game console.
A:AnswerThe only thing I can think of is in your settings, there's an 'auto dim' option. There are different levels to this, and it sounds like maybe you have it a bit too high?
A:AnswerUSB ports on today's TV's can be used for flash drives, whether for photos, movies, or music. Also, these are often utilized for various streaming devices, such as Amazon fire stick, Roku, Chromecast, etc.
