Precaution Of LCD Monitor

In order to use LED for backlight of a display, by interior temperature, brightness may change. In low temperature, the refreshing rate of the picture also becomes low because of the low response of the LCD monitor. When the interior becomes warm, however, the LCD recovers the normal display.
Backlight sometimes flickers or darkens according to the wearing out of LCD and the number of times switched ON and OFF. In this case, display unit should be replaced. (Exchange only of backlight is impossible.)
