A:AnswerRenee,
This IS a "SMART" TV. It has all the apps as my 65 inch 3D smart tv that is in the living room, but actually has other apps that my other does not, such as the ability to play "You tube" vids that my older set does not allow. It has the same apps and functions my other tv has and with even more that is now offered and more functions that my other smart tv does not have.
A:AnswerI bought a Dynex wall mount for TV's < 70 inches and it came with all necessary hardware and was 20-30 dollars. It was easy to install and totally worth it. Very secure and well made. Fit's this TV perfectly!
A:AnswerI did this using a "headphone to RCA plugs" adapter cable run to the RCA input jacks on my OLD (1994?) Sony receiver. If I recall correctly, I had to change the tv sound output setting (via the tv sound menu) to PCM as well.
