Definition: Brightness is a measure of TV light output (brightness) normally expressed in terms of CD/m2 or NIT. They are the same, 1 nit = 1 cd / m2. Brightness indicates how much luminous power the eye will detect when looking at a surface from a particular Angle. Thus, brightness is an indicator of how bright a surface will appear. Ordinary indoor LCD measure brightness in a range of 200 to 350 nits. While a 350-netter monitor may be sufficient in shaded outdoor areas, it will fail badly in bright or sunny environments. For brighter areas, LCD TVS with a minimum rating of 450 and a preferred rating of 700 nits perform much better. If you plan to display in full sun, you will need 1500+ nit rating. Simply placing a standard consumer TV outdoors can lead to a waste of money.
