A:AnswerYes it does need the box. The box holds all the connection points to other devices. The invisible connection cord connects the TV to the box. It is not a standard HDMI cord or anything like that.

A:AnswerI just purchased this TV a few days ago- The art mode does not allow you to adjust brightness or color and I am considering returning it unless thee is a technical update to allow this to occur
