Gain
This is used to adjust each color parameter for red, gr een and blue. An LCD monitor displays the color by
the light passing through the panel color lter. Red, green and blue are t he three primary colors. All t he
colors on the screen are displayed by combining these three c olors. The color tone can be changed by
adjusting the light intensity (volume) passing through each color’s lter.
Gamma
Generally, the monitor brightness varies nonlinea rly with the input signal level, which is called “Gamma
Characteristic”. A small gamma value produces a low-contra st 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 conte nts, such as video, music, etc.
This helps to transmit the digital contents sa fely by coding the digital contents sent via the DVI or HDMI
connector on the output side and decoding them on the i nput side.
Any digital contents cannot be reproduced if bot h of the equipments on the output and input sides are not
applicable to HDCP system.
HDMI (High-Denition Multimedia Interface)
HDMI is a digital interface standa rd, developed for consumer electrical appliance or AV device. This
standard is issued on the basis of the DVI standard which is one of an int erface specication for the
connection between a PC and a monitor. The projected image, sound and c ontrol signal without compressed
enable to be transmitted with one cable.
Overdrive
This technology enhances response sp eed by increasing the potential difference at t he time of motion of
liquid-crystal pixels, and it is used for liquid-cr ystal TV sets and others in general. It provides clear-cut
three-dimensional display with little after image, by improving response speed of the intermediate gr aduation
range that frequently appears in moving ima ges.
Rec709
Digital broadcasting (HDTV) sta ndards dened by the ITU-R (Inter national Telecommunication Union
Radio Communication Sector).
Resolution
The LCD panel consists of numerous pixels of speci��ed size, which are illum inated 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 scre en (1:1).
SMPTE-C
One of the standards provided by the SMPTE (Society of Motion Picture a nd Television Engineers).
