A:AnswerThe Tv is about 4 inches from wall, allowing room for tilt up & down or side to side. Can be pulled away from wall a couple more inches to reach all wires & connections. Very sturdy mounted to wall studs, & slides from side to side to center screen.
A:AnswerWhile the USB ports on this TV do output some voltage that can supply power to bias lighting or some streaming stick, but it may not provide enough power to enable a wireless HDMI device.
A:AnswerYour source has to be providing 4k signal. Any cable will transmit the 4k signal, better cables have less signal loss but should not change the resolution.
A:AnswerThese flat screen TVs use rear facing speakers and there is not much you can do with them, I use a sound bar with a sub woofer, this is the best way to improve the sound but there are other audio outputs to hook up a stereo receiver.
