Engadget - Here's yet another 84-inch 4K TV, this time from LG. The company's 84LM9600 was announced last week and has already started shipping in Korea, but it's here at IFA and poised to hit the market worldwide. Priced at about $22,105, this display is big in every way. You get a resolution of 3,840 x 2,160 -- four times the resolution of existing full HD panels -- and what LG calls "3D sound" thanks to 2.2 integrated channel speakers. 3D is courtesy of the company's passive glasses technology. So how does that all look?
