Afterimage
The Afterimage is particular to LCD monitors when the monitor screen is left on for a
long period without use. The "Afterimage" can be removed gradually by changing the
displayed image.
Clock
With the analog input signal display, the analog 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 clock pulse 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.
Color Temperature (Temperature)
Color Temperature is a method to measure the white color tone, generally indicated in
degrees Kelvin. At high temperatures the white tone appears somewhat blue, while at
lower temperatures it appears somewhat red. Computer monitors generally give best
performance at high temperature settings.
5,000 K: Slightly reddish white.
6,500 K: Warm-white tone, similar to white paper or daylight.
9,300 K: Slightly bluish white.
