DisplayPort
DisplayPort is a next-generation digital AV interface that allows connection of the PC, audio, imaging
devices, etc. to the monitor. One cable can transfer sound with images.
DVI (Digital Visual Interface)
DVI is a digital interface standard. DVI allows direct transmission of the PC’s digital data without loss.
This adopts the TMDS transmission system and DVI connectors. There are two types of DVI connectors.
One is a DVI-D connector for digital signal input only. The other is a DVI-I connector for both digital and
analog signal inputs.
DVI DMPM (DVI Digital Monitor Power Management)
DVI DMPM is a digital interface power saving function. The “Monitor ON (operating mode)” and “Active
Off (power saving mode)” are indispensable for DVI DMPM as the monitor’s power mode.
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
high-contrast image.
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 filter. 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 filter.
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.
Resolution
The LCD panel consists of numerous pixels of specified size, which are illuminated to form images. This
monitor consists of horizontal 4096 pixels and 2160 vertical pixels. At a resolution of 4096 × 2160, 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.
