A:AnswerThe TV speakers I guess are adequate for some viewing. But if you want good sound and good bass. Then I would go with a soundbar or a surround sound system. Running the video through a good AV receiver improves the quality tremendously.
A:AnswerNot sure of the exact weight, but it can be installed on a wall mount. This TV replaced a 55” plasma and it weighs less than the old plasma tv.
A:AnswerIf your device has A HDMI cord outlet then yes. Just hook one end to the device then to the TV. If you have Airplay on your phone or device you can share your screen that way as well
