Te r minology
 
						

							English-46 Interlace (Page 32, 45)
One of the formats for displaying a frame that scans every
other line of the frame. It is possible to use this format when
displaying a screen that contains movement, such as TV,
but not for when displaying still images as flickering of the
screen is conspicuous. As a result, most computer monitors
use a progressive format, which suppresses flickering of still
images.
Energy Star Program (Page 2, 47)
Program that is being promoted by the US Environmental
Protection Agency (EPA) in order to reduce power
consumption of desktop computers.
Overscan (Page 30)
Refers to displaying pictures so that a few % of the effective
picture that is input falls outside of the display area of the
monitor’s screens (the part that is outside of the display area
is not displayed on the screen). Regular TV is adjusted in an
overscan state.
Response time (Page 47)
Refers to the speed at which screens switch when the
displayed screen is changed (follow), where a smaller
number represents a faster response time. The response
time is the total amount of time necessary for changing from
black → white → black tones.
Brightness (Page 47)
Refers to the pitch for brightness per unit area, where a
higher number represents a brighter display screen.
Contrast ratio (Page 47)
Refers to the ratio that indicates the ratio of the brightness
of white and black colors. If the brightness is the same, a
higher contrast ratio represents a sharper screen.
Component picture (Page 4, 13)
Picture signals are divided into brightness signals (Y) and
color signals (red (Pb)/blue (Pr)), synthesized by the
receiving display device when projecting the signals on the
screen, and then turned into a picture. Since brightness
signals and color signals are sent separately, it is possible to
reduce deterioration of image quality that occurs easily in
conventional analog TV broadcasting, such as unnecessary
coloring and blurring of colors.
Side border color (Page 28, 33)
Function that adjusts the colors of the parts on both ends of
the screen where there is no picture if using aspect display.
Residual image (Page 38)
Residual images are images of the previous screen that was
displayed that remain after the screen display is changed,
when the same screen is displayed for a long period of time.
Residual images gradually disappear if the screen display
changes. However, they eventually may not disappear if the
same screen is displayed often for long periods of time;
avoid using the monitor where the same screen is displayed
for long periods of time. It is recommended to change the
display screen by using [Screensaver], etc.
View angle (Page 38, 47)
Refers to the angle from which a regular picture is viewed,
such as when looking at a picture diagonally. A larger view
angle indicates that it is possible to view pictures from a
broader range.Horizontal frequency/Vertical frequency (Page 33, 47)
Horizontal frequency: Refers to the number of horizontal
lines displayed in 1 second. If the horizontal frequency is
31.5 kHz, horizontal lines are displayed 31,500 times per
second.
Vertical frequency: Represents the number of times the
screen is rewritten in 1 second. If the vertical frequency is
60 Hz, the screen is rewritten 60 times per second.
Tilt angle/Swivel angle (Page 16, 47)
Tilt angle: Refers to the angle that the monitor screen can
be moved up and down.
Swivel angle: Refers to the angle that the monitor screen
can be rotated in the horizontal direction.
No Touch Auto Adjust (NTAA) (Page 34)
Function that automatically sets the optimal condition for the
screen each time a new signal is received from the
computer.
Noise reduction (Page 32)
Reduces minute roughness (noise) in the picture.
Power Management function (Page 34)
Function that is built in to reduce power consumption of the
computer. Reduces electric power consumption when the
computer is not used for a fixed period of time (there is no
key input over a fixed period of time). Returns to a normal
state when you want to use the computer again.
Display pixels/resolution (Page 29, 33, 34, 47)
Commonly referred to as “resolution.” Represents the
number of pixels in the horizontal and vertical directions per
screen. A larger number of display pixels enables for a
larger amount of information to be displayed.
Progressive (Page 32, 45)
One of the formats for displaying a frame by the screen
(frame) at once. Format that displays all pixels by scanning
in order from the top, and which is why it is referred to as
the progressive scanning method. Compared to the interlace
method, there is less flickering of the screen, enabling for
clearer images. Also referred to as noninterlace.
