The guide used internationally by imaging experts for a 1080p 16x9 display, is a 30 degree viewing angle (for average 20/20 vision). That closely equates with 1.5 x screen diagonal. A seating distance according to those recommendations places the average viewer close enough to perceive maximum image resolution, without detecting pixel structure. Sitting closer results in a pixelated image. Farther away and the viewer will lose detail in the program's image and also diminish the sense of immersion in the action on the screen. These are averages that work for most viewers.I am considering buying a 70" TV, and my main viewing distance is about 14 feet. Will this be too big?
