HDCP (High-bandwidth Digital Content Protection)
Digital signal coding system developed to copy-protect the digital contents, such as video, music,
etc.
This helps to transmit the digital contents safely by coding the digital contents sent via the DVI or
HDMI connector on the output side and decoding them on the input side.
Any digital contents cannot be reproduced if both of the equipments on the output and input sides
are not applicable to HDCP system.
Overdrive
This technology enhances response speed by increasing the potential difference at the time of
motion of liquid-crystal pixels, and it is used for liquid-crystal TV sets and others in general. It
provides clear-cut three-dimensional display with little afterimage, by improving response speed of
the intermediate graduation range that frequently appears in moving images.
Phase
Phase means the sampling timing to convert the analog input signal to a digital signal. Phase
adjustment is made to adjust the timing. It is recommended that phase adjustment be made after
the clock is adjusted correctly.
Range Adjustment
Range adjustment controls the signal output levels to display every color gradation. It is
recommended that range adjustment be made before color adjustment.
Resolution
The LCD panel consists of numerous pixels of specified size, which are illuminated to form images.
This monitor consists of horizontal 1600 pixels and 1200 vertical pixels. At a resolution of 1600 ×
1200, all pixels are illuminated as a full screen (1:1).
sRGB (Standard RGB)
International standard for color reproduction and color space among peripheral devices (such as
monitors, printers, digital cameras, scanners). As a form of simple color matching for the Internet,
colors can be displayed using tones close to those of the transmission and reception devices.
Temperature
Color temperature is a method to measure the white color tone, generally indicated in degrees
Kelvin. The screen becomes reddish at a low temperature, and bluish at a high temperature, like
the flame temperature.
5000 K: Slightly reddish white
6500 K: White referred to as daylight-balanced color
9300 K: Slightly bluish white
TMDS (Transition Minimized Differential Signaling)
A signal transmission system for digital interface.
VESA DPM (Video Electronics Standards Association - Display Power
Management)
VESA specifications achieve increased energy efficiency for computer monitors. This involves
standardization of signals sent from the computer (graphics board).
DPM defines the status of signals transmitted between the computer and monitor.
