configured receptacles marked between 100 - 240V AC, Min. 5A.

z The wall socket shall be installed near the equipmen t and s hall be easily ac c es s ible.

Special Notes On LCD TV Monitors

The following symptoms are normal with LCD TV monitor and do not indicate a problem.

Notes

z Due to the nature of the fluorescent light, the screen may flicker during initial use. Turn off the Power Switch

and then turn it on again to make sure the flicker disappears.

z You may find slightly uneven brightness on the screen depending on the desktop pattern you use.
z The LCD TV screen has effective pixels of 99.99% or more. It may include blemishes of 0.01% or less such

as a missing pixel or a pixel lit all of the time.

z Due to the nature of the LCD TV screen, an afterimage of the previous screen may remain after switching

the image, when the same image is displayed for hour s. In this case, the screen is recovered slowly by
changing the image or turning off the Power Switch for hours.

How To Optimize The DOS-Mode
Plug And Play
Plug & Play DDC2B Feature

This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD. It allows
the monitor to inform the host system of its identity and, depending on the level of DDC used, communicate
additional information about its display capabilities.

The DDC2B is a bi-directional data channel based on the I²C protocol. The host can request EDID
information over the DDC2B channel.

This monitor will appear to be non-functional if there is no video input signal. In order for this
monitor to operate properly, there must be a video input signal.

This monitor meets the Green monitor standards as set by the Video Electronics Standards Association
(VESA) and/or the United States Environmental Protection Agency (EPA) and The Swedish Confederation
Employees (NUTEK). This feature is designed to conserve electrical energy by reducing power
consumption when there is no video-input signal present. When there is no video input signals this monitor,
following a time-out period, will automatically switch to an OFF mode. This reduces the monitor's internal
power supply consumption. After the video input signal is restored, full power is restored and the display is
automatically redrawn. The appearance is similar to a "Screen Saver" feature except the display is
completely off. The display is restored by pressing a key on the keyboard, or clicking the mouse.

Using The Right Power Cord

The accessory power cord for the Northern American region is the wallet plug with NEMA 5-15 style and is
UL listed and CSA labeled. The voltage rating for the power cord shall be 125 volts AC.
Supplied with units intended for connection to power outlet of personal computer: Please use a cord set
consisting of a minimum No. 18 AWG, type SJT or SVT three conductors flexible cord. One end terminates
with a grounding type attachment plug, rated 10A, 250V, CEE-22 male configuration. The other end
terminates with a molded-on type connector body, rated 10A, 250V, having standard CEE-22 female
configuration.
Please note that power supply cord needs to use VDE 0602, 0625, 0821 approval power cord in European
counties.

White-Balance, Luminance Adjustment

Chapter 6

Approximately 30 minutes should be allowed for warm up before proceeding white
balance adjustment.

Before started adjust white balance ,please setting the Chroma-7120

MEM. channel 2 to 10000

( our 12000 parameter is x = 272 ± 15, y = 278 ± 15, Y = 350 ± 7 cd/m2 ;
10000 parameter is x = 279 ± 15, y = 290 ± 15, Y = 350± 7 cd/m
8000 parameter is x = 295 ± 15, y = 305 ± 15, Y = 350± 7 cd/m

“
Following is the procedure to do white-balance adjust

” key to modify x, y , Y value and use “ID” key to modify the TEXT description

I.Press Number key Power key + manual will into the factory mode, and press Menu key the
OSD will show menu and a word “F” at LEFT top of Menu.

1. In the factory mode select “COLOR TEMP” may be select the difference color temp.

2. Select SCALER Adjustment:
RG, GG, BG Æ R, G, B Gain adjust.

RB, GB, BB Æ R, G, B Bias adjust.

<Notes: the R, G, B gain use 9 bits, and R, G, B bias use 10 bits to save the value in EEPROM,

so if the R, G, B gain and bias is 255 to 256, the “P0 256”will change to “P10”>

Notes: adjust AV mode the same as PC mode, except the luminance (Pc mode is 350cd/m2,
Av is 350cd/m2).

II. Bias (Low luminance) adjustment:

1. Set the raster pattern (Black pattern with 800×６００) Input.

2. Set the contrast on OSD window to the value=80, Brightness set to “80”

3. Adjust the brightness on OSD until chroma 7120 measurement reach the lowest value.
