9. White- Balance, Luminance Adjustment
Approximately 30 minutes should be allowed for warm up before proceeding White-Balance adjustment. 1. How to do the Chroma-7120 MEM. Channel setting A. Reference to chroma 7120 user guide B. Use SC key and NEXT key to modify XyY value and use ID key to modify the TEXT description Following is the procedure to do white-balance adjust 2. Setting the color temp. you want A. MEM.CHANNEL 3 (7800 color): 7800 color temp. parameter is x = 296 B. MEM.CHANNEL 4 (6500 color): 6500 color temp. parameter is x = 313 20, y = 329 3. Into factory mode of AOC LM929 20, Y =180 cd/m2 20, y = 311 20, Y = 180 cd/m2 ,
Turn on power, press the MENU button, pull out the power cord, and then plug the power cord. Then the factory
4. Bias adjustment: Set the Contrast 5. Gain adjustment: Move cursor to -F- and press MENU key A. Adjust 7800 color-temperature to 50; Adjust the Brightness to 80.
1. Switch the Chroma-7120 to RGB-Mode (with press MODE button) 2. Switch the MEM. Channel to Channel 3 (with up or down arrow on chroma 7120) 3. The LCD-indicator on chroma 7120 will show x = 296 20, y = 311 20, Y =180 cd/m2

4. Adjust the RED of color1 on factory window until chroma 7120 indicator reached the value R=100 5. Adjust the GREEN of color1 on factory window until chroma 7120 indicator reached the value G=100 6. Adjust the BLUE of color1 on factory window until chroma 7120 indicator reached the value B=100 7. Repeat above procedure (item 4,5,6) until chroma 7120 RGB value meet the tolerance =100 B. Adjust 6500 color-temperature 2
1. Switch the chroma-7120 to RGB-Mode (with press MODE button) 2. Switch the MEM.channel to Channel 4(with up or down arrow on chroma 7120) 3. The LCD-indicator on chroma 7120 will show x = 313 20, y = 329 20, Y = 180 cd/m2
4. Adjust the RED of color3 on factory window until chroma 7120 indicator reached the value R=100 5. Adjust the GREEN of color3 on factory window until chroma 7120 indicator reachedthe value G=100 6. Adjust the BLUE of color3 on factory window until chroma 7120 indicator reached the value B=100 7. Repeat above procedure (item 4,5,6) until chroma 7120 RGB value meet the tolerance =100 C.

GENERAL NOTES

SPECIAL NOTES ON LCD MONITORS
The following symptoms are normal with LCD monitor and do not indicate a problem. 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. You may find slightly uneven brightness on the screen depending on the desktop pattern you use. The LCD panel used in this monitor is a very high technology product with 3,932,160 thin film transistors giving you fine picture details. Occasionally, a few non-active pixels may appear on the screen as a fixed point of red, green, blue, white or black. Please note that this does not indicate a defective panel. Due to the nature of the LCD screen, an after-image of the previous screen may remain after switching the image when the same image has been displayed for a long time. The monitor will slowly recover from this. LCD monitors have a fixed size & number of pixels. Due to this, an interpolation is necessary to operate the monitor in a relution below its native resolution which may slightly degrage the display quality. Therefore, it is highly recommended to operate the monitor at its native resolution of 1280 x 1024 @ 60Hz.

OTHER NOTES

The screen surface is very soft. Do not rub, touch or tap the screen surface with sharp object such as pen or pencil. This contact may scratch or damage the screen. These damages are not covered under the warranty. Turn your computer OFF before installing your new monitor. Refer to your computer manual for the proper shut down procedure. Save the original shipping carton and packing materials, as they will come in handy if you ever have to ship your monitor. For maximum protection, repackage your monitor as it was originally packed at the factory. To keep the monitor looking new, periodically clean the case & surface of the TFT-LCD panel with a soft non-fiberous cloth lightly dampened with a glass cleaner. Do not use any paper products to clean the screen. Never spay the glass cleaner directly on the monitor. Never use strong solvents such as thinner, benzene, or abrasive cleaners, since these will damage the case & panel. As a safety precaution, always unplug the monitor before cleaning it.

GENERAL NOTES (cont)

Plug & Play DDC 2B Feature - This monitor is equipped with VESA
DDC 2B capabilities according to the VESA DDC STANDARD.
