HDCP (High-bandwidth Digital Contents 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 DVI terminal 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.
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 specied size, which are illuminated to form images.
This monitor consists of 1680(CG223W) / 1920(CG243W) horizontal pixels and 1050(CG223W) /
1200(CG243W) vertical pixels. At a resolution of 1680 x 1050(CG223W) / 1920 x 1200(CG243W) , all
pixels are illuminated as a full screen (1:1).
sRGB(Standard RGB)
"International Standard for Red, Green, and Blue color space" A color space was dened with the aim of
the color matching between applications and hardware devices, such as monitors, scanners, printers and
digital cameras. As a standard default space, sRGB allows Internet users to closely match colors.
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 ame
temperature.
5000K: Slightly reddish white (usually used in print industry)
6500K: White called daylight color (suited for web browsing)
9300K: Slightly bluish white (usually used for television)
TMDS (Transition Minimized Differential Signaling)
A signal transmission system for digital interface.
VESA DPM (Video Electronics Standards Association - Display Power Management )
VESA specications achieve increased energy efciency for computer monitors. This involves
standardization of signals sent from the computer (graphics board). DPM denes the status of signals
transmitted between the computer and monitor.
