Viewing angle is directly related to contrast ratio.
Contrast ratio is defined as the ratio of the brightness of a white image to the brightness of a black image.
Normally from the centre of a monitor or TV viewing angle is 140°,Contrast ratio 250:1
If you are displaced 70° from the centre then the contrast ratio becomes 10:1 or 5:1
(70° from the centre means move aside from centre to one end where you can view the screen).
