Display Brightness: Maximum & Minimum
A display’s brightness or luminance—measured in candelas per square meter (cd/m2) or nits—affects its visibility in different lighting conditions. A higher maximum brightness makes the screen easier to see in bright conditions such as a brightly lit room or in direct sunlight outdoors. For a dimly lit room or at night, a lower minimum brightness is preferable to keep your screen from blinding you or bothering others around you.
