Approximately 30 minutes should be allowed for warm up before proceeding white balance adjustment.
YPbPr Mode display adjustment White balance adjustment (B)
General set-up:
Equipment Requirements: Minolta CA-110 or Equivalent Color analyzer Quantum Data Pattern Generator 802G, 802BT or equivalent instrument Input requirements:
Input Signal Type: YPbPr signal
1. 720P mode, TVBar100 pattern by 802G or 802BT.
2. Select Smart picture to User mode and check the x, y data. Input Signal Strength: 1 Vpp for Y signal; 700 mVpp for Pb & Pr signal Input Injection Point: YPbPr (RAC jack)
Alignment method Acer AT2230 & AT2231 :
Initial Set-up:
1. Select source as “Component”.
2. Set Smart picture as “User” and to be Contrast =50(TBD) (CMO), Brightness=50(TBD) (CMO), at normal menu mode.
3. Apply “TVBar100” pattern with color bar pattern by signal generator.
4. Enter factory mode menu: press “MENU + “234” then enter FAC mode.
Alignment:
1. At FAC mode menu, select FACTORY->Picture ->ADC -> Auto Colour item. Then press “>” key to adjust
ADC_GAIN_R, ADC_GAIN_G, ADC_GAIN_B and ADC_OFFSET_R, ADC_OFFSET_G, ADC_OFFSET_B. Then store those values to NVM.
White- Balance alignment Acer AT2230 & AT2231 :
1. Select source as “HDMI1”
2. Apply Flat pattern (100% white pattern), at FAC mode menu, select Factory -> Picture -> Colour Temp item
3. Set color temperature to “Standard”.
4. Adjust the R Gain, G Gain, B Gain values to meet “Standard” color coordinates specification below. Then store those values to NVM.
5. Set color temperature to “Warm”.
6. Adjust the R Gain, G Gain, B Gain values to meet “Warm” color coordinates specification below. Then store those values to NVM.
7. Set color temperature to “Cold”.
8. Adjust the R Gain, G Gain, B Gain values to meet “Cold” color coordinates specification below. Then store those values to NVM.
Note:
1. Use Minolta CA-110 for colour coordinates and luminance check.
2. Luminance > 250 cd/m2 in the center of the screen when Brightness control at 100; Contrast control at 100
3. Reset AV setting, smart picture shall be recalled to be “Standard” and Contrast=50 (CMO), Brightness=50 (CMO)
PC mode display adjustment WHITE-D adjustment (B)
