9.White- Balance, Luminance Adjustment
Approximately 30 minutes should be allowed for warm up before proceeding white balance adjustment.
How to setting MEM channel you can reference to chroma 7120 user guide or simple 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 .
1. Setting the color temp.
A. 6500K:
Warm color temp. parameter is x=313±30
，
y=329±30
B. 7300K
Normal color temp. parameter is x=302±30
，
y=318±30
C. 9300K
Cool color temp. parameter is x=283±30
，
y=297±30
D. sRGB
sRGB color temp. parameter is x=313±30
，
y=329±30
2. Enter into the factory mode:
Press the MENU button,Pull out the power cord, then plug the power cord. Then the factory OSD will be at the
left top of the panel.
3. Biase adjustment:
Set the Contrast
to 50; Adjust the Brightness
to 90.
4. Gain adjustment:
A. Adjust Warm (6500K) color-temperature
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=313±30
，
y=329±30
4. Adjust the RED on factory window until chroma 7120 indicator reached the value R=100
5. Adjust the GREEN on factory window until chroma 7120 indicator reachedthe value G=100
6. Adjust the BLUE on factory window until chroma 7120 indicator reached the value B=100
7. Repeat above procedure (item4, 5, 6) until chroma 7120 RGB value meet the tolerance =100±2
B. Adjust Normal (7300K) color-temperature
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=302±30
，
y=318±30
