A:AnswerYes sir it definitely supports 4K although I'm not so sure about 3D. I currently have an LG 60" inch 4K UHD. It uses the system ARC(Audio Return Channel) which is an HDMI cable that transmits between the TV and sound system. Most 4K TV's built in 2014 have the ARC option built into them. If your TV does not have this option then an optical cable could be used instead. Make sure to check the HDMI ports on your TV and check to see if there is an ARC label right under it. Though I had to enable ARC on my LG TV in order for it to work.
A:AnswerIt is wireless. It will connect to anything with HDMI, so it will connect to your AV receiver if it has HDMI out. You probably wouldn't need the receiver with this as it puts out great sound.
A:AnswerIt's in the rear of the bar. I have my cord running through a cut out in the wall so it is not visible with only one HDMI cable connected. If you hook up multiple cables to it they will be visible as the inputs are near the top of the bar.
