LCD monitor for a long time, considerations for continuous
use
LCD screen may cause deterioration of the blot-like partial continuous operation when
using the monitor. This phenomenon is caused by deterioration due to changes in the
chemical properties of liquid crystals.
This screen is non-uniform degradation occurs in the liquid crystal composition can be
extended screen, is appearing as black blotches on the screen as a result. They are
more likely to occur at high temperatures by the use of a long and continuous use in
particular.
If the monitor is not being used, or turned off, OS you can perform the power saving
