A:AnswerNo. Wallmoun and installation is separate from the delivery and connection.
If you get the installation it doesn't include above the fireplace if that's where you want it installed.
You must purchase the Wallmoun Best Buy will install it for a fee.
A:AnswerEach one as the series goes up is more standard options, higher picture quality, sound quality. I bought the 8 series 75 inch and the picture color and overall quality of what you are watching is very visible if you watch them side by side which I did. Obviously you pay more for an 8 than a 6 or 7 but at the end of the day try see them side by side and choose what works for you.
