10. White- Balance, Luminance Adjustment

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

Before started adjust white balance , please set the Chroma-7120 MEM Channel 3 to Warm (6500K) color, MEM Channel 4 to Normal (7300K) color, MEM Channel 9 to Cool (9300K) color , and MEM Channel 10 to sRGB color ( our Warm color parameter is x = 283 ±30, y = 297 ±30, Y=180cd/m2; Normal color parameter is x = 301 ±30, y = 317 ±30, Y=190cd/m2; Cool color parameter is x = 313 ±30, y = 329 ±30, Y = 200 cd/m2; sRGB color parameter is x = 313 ±30, y = 329 ±30, Y = 180cd/m2)

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 .

2. Setting the color temp. you want A. MEM.CHANNEL 3 (Warm color):

Warm color temp. parameter is x = 283 ±30, y = 297 ±30, Y=180cd/m2 B. MEM.CHANNEL 4 (Normal color):

Normal color temp. parameter is x = 301 ±30, y = 317 ±30, Y=190cd/m2 C. MEM.CHANNEL 9 (Cool color):

Cool color temp. parameter is x = 313 ±30, y = 329 ±30, Y = 200 cd/m2 D. MEM.CHANNEL 10 (sRGB color):

sRGB color temp. parameter is x = 313 ±30, y = 329 ±30, Y = 180cd/m2 3. Into Factory mode of AOC 919Swa
