· The LCD monitor is designed for analog input
signals from a standard graphics board. The
analog input signal is converted to a digital signal
by the LCD circuitry. To convert the signal
correctly, the LCD monitor needs to produce the
same number of clock pulses as the dot clock of
the graphics system. When the clock pulse is not
correctly set, some vertical bars of distortion are
displayed on the screen.
· When adjusting the “Clock”, the horizontal screen
size will also change.
