A:AnswerYes but it is easy to download another browser if you do not like the one offered. I liked my 55 in so well that when they went on sale again, I bought another one. Enjoy your purchase.
A:AnswerSince I didn't receive a response, I am going to assume this TV cannot play video files from a USB flash drive. I will be returning this back to BestBuy.
A:AnswerTry this: Go Home > Settings > Display and Sounds > HDMI CEC Device Control and turn ON; then Home > Settings > Display and Sounds > Audio Output > Turn TV Speakers OFF and Select Digital Audio Format Auto.
