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 functioning properly), no defect is considered to exist.
The screen becomes disordered
The screen display may become distorted if the resolution or number of colors
is changed, or if an external display is connected or disconnected while the
computer is operating. Restart the computer.

with the computer, the display may not function correctly when the computer
enters the power saving mode. In such cases, turn off the power to the external
display.
