which the mirror is a digital representation of 0s and 1s, leaving no trace of light.
The mirror returns to a blank state so that no stains or after-images are left.
- A too long DVI cable may cause a malfunction or degradation of the visual quality due to an
attenuation of the signal. There is no recommendation for the cable length at present.
In general, although a cable length of up to 5 meters should work, please check if video is
properly displayed on the screen after connecting. If you think the length of the cable is longer

length, if necessary.
- This also applies to the PC RGB (D-Sub) cable. When the length of the cable is longer than
for normal use, video may not be displayed on the screen. In this case, shorten the cable
length.

SD/HD broadcasts and the TV's display capability are related
1. A digital broadcast should be transmitted in wide screen (an aspect ratio of 16:9) HD. If the broadcasting station converts a
conventional program created in normal screen (aspect ratio of 4:3) into a digital signal and broadcasts the signal, the left and
right of the picture will not be displayed.
This symptom also appears in other manufacturer's TV's. The three appliance companies are trying to resolve the problem
through the Ministry of Information and Communication.

Restrictions
1. When you want to change the picture size in PIP 'ON', you must turn the PIP off before changing the size.
However, you can change the main picture size even in PIP ON for products with no restrictions.
2. When the picture size is not Normal (4:3 for 4:3 display devices, 16:9 for 16:9 display devices) and you turn PIP on, the picture
size is changed to Normal.
However, you can turn PIP on without changing the picture size for products with no restrictions.
3. In the OSD notation for the picture size, 16:9 is represented as "Wide" instead of "16:9" for devices other than with 16:9 dis
plays.
Ex: For LCD 15:9 devices, "Wide" is displayed on the OSD instead of "16:9".
4. The picture size can be changed even in the blue screen.
However, the picture size should be controlled by the product specifications if the change is impossible due to hardware
restrictions.

Pixels, Resolution
The pixels are the number of small dots that make up the TV screen. The resolution represents the number of pixels on a screen.
For example, if the resolution of a TV is 852x480, it means the width of the screen consists of 852 pixel columns and the height of
the screen consists of 480 pixel rows. In this case, the total number of pixels on the screen is 408,960. The more pixels there are,
the higher the visual quality that can be achieved because the picture on the screen is displayed with more pixels and therefore
with more detail.
852
480
42SD = 409K Pixels
Gradation, Color Depth
Gradation describes the number of gradual brightness levels. Since all information is represented by binary numbers in a digital
system, the Gradation is determined by the number of bits used to represent the brightness levels of a pixel on the TV screen. For
example, if a pixel is represented by 8 bits, the Gradation is 28 or 256. Since a TV uses the three primary colors of light, R, G and
B, the number of possible colors for a pixel is 256 x 256 x 256, 16,777,216, or 16.7 million colors. If 12 bits are used for a pixel, the
gradation is 212 or 4096 for a color. Since three colors R, G and B are used, 4096 x 4096 x 4096 or 68.7 billion colors are support-
ed per pixel. Since 68.7 billion colors are far more than 16.7 million colors, the picture will be displayed by far more abundant and
natural colors using a 12 bit pixel. That is, since Gradation means the number of brightness levels, color represented by 4096 lev-
els appears more natural than color represented by 256 levels.
Contrast
The contrast is the ratio of brightness of the brightest color to the darkest color. The contrast is calculated by dividing the bright-
ness of the brightest color by the brightness of the darkest color. For example, if the brightness of the darkest color is 1 and the
brightness of the brightest color is 3000, then the Contrast is 3000/1 or 3000. A higher contrast means that a dark color is dis-
played darker and bright color is displayed brighter so that the screen contrast can be easily distinguished. The contrast differs
from the Gradient which means the number of brightness levels.
Therefore, if someone says that a 5000:1 contrast displays a color by 5000 levels, he is confusing Contrast with Gradation.
Brightness
Brightness is the brightness per unit screen area, the unit for brightness is candela (cd). For example, 1000cd/m2 means the
brightness that is measured when 1000 candles are lit within 1 square meters area.

Color Reproductivity
Each color displayed on the TV screen is implemented by a pixel on color coordinates which have an X and Y axis.
For example, when a pixel on the X coordinate 0.65 and the Y coordinate 0.74 is displayed as a
color and it becomes visible on the TV screen. While the possible color coordinate area is very
wide, the color coordinate area of the signal broadcast from a broadcast station is smaller than
that of possible color coordinates. Moreover, a TV provides a smaller color coordinate area than
that of the signal from the broadcasting station even though the size of the color coordinate area
varies depending on the TV model. In general, Color Reproductivity is used as follows:
The Color reproductivity of a TV is a certain % of NTSC. This means the TV displays that
particular % of the color coordinate area of the NTSC signal broadcast by the broadcasting
station. In general, a CRT TV provides the highest functional color reproductivity.
