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.
DVI
(Digital Visual Interface)
A digital flat panel interface. DVI can transmit digital data from the PC directly
without loss with the signal transition method “TMDS”.
There are two kinds of DVI connectors. One is DVI-D connector for digital signal
input only. The other is DVI-I connector for both digital and analog signal inputs.
DVI DMPM
(DVI Digital Monitor Power Management)
The Power management system for the digital interface. The “Monitor ON” status
(operation mode) and the “Active Off” status (power-saving mode) are indispensable
for the DVI-DMPM as the monitor’s power mode.
EIZO MPMS
(EIZO Monitor PowerManager Signaling)
EIZO MPMS, “EIZO Monitor PowerManager Signaling” also enables power saving
on the monitor side. EIZO MPMS recognizes video signals from the PC when the PC
is in a power saving mode and reduces energy consumption of the monitor.
Gain Adjustment
Adjusts each color parameter for red, green and blue. The color of the LCD monitor
is displayed through the color filter of the LCD panel. Red, green and blue are the
three primary colors. The colors on the monitor are displayed by combining these
three colors. The color tone can change by adjusting the illumination amount passed
through each color’s filter.
Gamma
Generally, the relationship that the light intensity values of a monitor change
nonlinearly to the input signal level is called “Gamma Characteristic”. On the
monitor, low gamma values display the whitish images and high gamma values
display the high contrast images.
