If an image is displayed for a prolonged period of time, an afterimage may appear. This
is not a malfunction. The afterimage will disappear when a different screen is displayed.
High-precision and advanced technologies are necessary in the production of color liquid
crystal displays (color LCDs). Therefore, if 0.002% or less of the picture elements either
fail to light or remain constantly lit (that is, more than 99.998% of elements are function-
ing properly), no defect is considered to exist.
When an external display not compatible with the power saving mode is used with the
computer, the external display may no longer display properly when the computer enters the
condition the power of the display is OFF (for energy conservation purposes). In such
cases, turn off the power to the external display.
