Thank you for reaching out with interest in a 55" Vizio TV. Vizio makes great TV's for an affordable price.
Are you planning on using your TV in the United States or in Việt Nam? Please be aware all items that are sold on BestBuy.com are meant to be used within the US. Due to the differences in electrical currents, and regulations in different countries we're unable to recommend items for use outside of the United States.
If you're interested in purchasing a TV to use while you're in the US I'd be happy to help make a recommendation for you based on your needs.
