A:Answeryes, this tv has HDR10. every single HDR tv on bestbuys site says "HDR compatible" so the other reviewers that say it doesn't have HDR are uninformed and cant seem to do 5 minutes of research outside of bestbuy. Pretty sad so many non-smart people spread false information.
A:AnswerYes it does have speakers om the back. If you want good sound for music, buy a sound bar. I did. Otherwise, this is an excellent tv and a very good buy.
A:AnswerNeed to go into setup. I think under power option. A few options available. I set for cable tv as default. When turned on it begins with cable input.
