Viewing angle is a property of LCD monitors, since as far as CRT monitors are concerned, the display can be viewed in all directions as long as you are in front of the screen. Viewing angle is the maximum angle through which a person will be able to see the monitors display perfectly. The viewing angle accounts for both horizontal and vertical views.
LCD monitors which are used at home may have larger viewing angles and the ones used in office rooms, probably has smaller viewing angles on account of security.
So when a LCD television is bought make sure that it has good viewing angle for better visibility for all the people who are watching.
Viewing angles is represented by “x/y”.
X > the horizontal viewing angle (in degrees).
Y > the vertical viewing angle (in degrees).
For example , 160/160.
