text: I am just one person, but managed to unpack it and set it up, despite them saying two people are best to do what lifting and set up. I had some trouble trying to figure out how to attach the legs, but finally figured it out. You insert the assembly through a slot on the bottom of the screen. I had to phone tech support to get some of it working, and Sony online registration didn't work. My 2013 sound bar isn't supported, so I have to adjust the sound volume physically, not by the remote. The sound bar doesn't have a HDMI connection, so the remote can't adjust the sound. As far as 4K, I see little difference from my HD Panasonic. My movies in 4K aren't very sharp, although streaming 4K videos by some apps seems to be O.K. I do have a 60" screen, much better than say my 50" former TV, and it's a lot brighter than my 2007 Sony. I tried to hook up my computer by HDMI cable, but for some reason it didn't seem to work. I may try that again, but I'll have to see. All in all, if I had known that this was so disappointing, I'd have saved my money. Subjectively, the image quality of my older Panasonic seems just as good, and 4K looks to be not worth it. As a return would be such a hassle, being that the box gets somewhat destroyed as you unpack it, my advice is not to get this. Unless you have to have the latest and greatest, save your money. The sound level varies from what usage, so the remote not working with my sound bar is a reason for me favoring never having bought this in the first place.
