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

Before started adjust white balance of Acer AT2010 LCD TV , please setting the Chroma-7120 MEM. Channel 1 to 14000 color, MEM. channel 2 to 12000 color, MEM. channel 3 to 9300 color, MEM. channel 4 to 8000 color, and MEM.
channel 5 to 6500 color, ( our 14000 parameter is x = 266 ± 15, y = 270 ± 15, Y = 300 ± 7 cd/m2 ; 12000
parameter is x = 272 ± 15, y = 278 ± 15, Y = 300± 7 cd/m2 ;9300 parameter is x = 283 ± 15, y = 297 ± 15, Y= 300± 7 cd/m2;8000 parameter is x = 295 ± 15, y = 305 ± 15, Y = 300± 7 cd/m2;6500 parameter is x = 313 ±15, y = 329 ± 15, Y = 300± 7 cd/m2)
How to setting MEM. channel you can reference to Chroma-7120 user guide or simple use “ SC” key and “ NEXT” key to modify x, y , Y value and use “ID” key to modify the TEXT description Following is the procedure to do white-balance adjust

I. Press Number key 1 => 9 => 9 => 9 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  => R, G, B Gain adjust. RB, GB, BB => 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 420cd/m2).
