Gain
This is used to adjust each color parameter for red, green and blue. An LCD monitor displays the color by
the light passing through the panel color lter. Red, green and blue are the three primary colors. All the
colors on the screen are displayed by combining these three colors. The color tone can be changed by
adjusting the light intensity (volume) passing through each color’s lter.
Gamma
Generally, the monitor brightness varies nonlinearly with the input signal level, which is called “Gamma
Characteristic”. A small gamma value produces a low-contrast image, while a large gamma value produces a
highcontrast image.
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.
HDMI (High-Denition Multimedia Interface)
HDMI is a digital interface standard, developed for consumer electrical appliance or AV device. This
standard is issued on the basis of the DVI standard which is one of an interface specication for the
connection between a PC and a monitor. The projected image, sound and control signal without compressed
enable to be transmitted with one cable.
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.
Rec709
Digital broadcasting (HDTV) standards dened by the ITU-R (International Telecommunication Union
Radio Communication Sector).
Resolution
The LCD panel consists of numerous pixels of specied size, which are illuminated to form images. This
monitor consists of horizontal 2560 pixels and 1440 vertical pixels. At a resolution of 2560 × 1440, all pixels
are illuminated as a full screen (1:1).
SMPTE-C
One of the standards provided by the SMPTE (Society of Motion Picture and Television Engineers).
