Looks like the next big thing in TVs will be 4K displays, or as LG likes to call them, ultra definition displays. The Korean company has just unveiled their own 4K display in Korea earlier today. This 84-inch behemoth uses LG’s triple XD image engine, which compliments the TV’s eye popping 3840×2160 native resolution. This particular TV also boasts 3D functionality, and sports LG’s Smart TV functionality. It also uses LG’s Smart Remote, and LG promises that this particular device has access to multitude of apps available to LG’s Smart TVs. No local availability has been set yet, so Toshiba’s RZ1 can still sleep soundly tonight.
