D. Color adjustment: 1. Setup input timing ICL-605, white pattern . 2. Confirm auto color adjustment had already done. 3. Measure color temperature by Minolta CA-110 (or equivalent equipment). 4. Check the color temperature Bluish, Reddish & Normal. The color temperature specification as follows: White Balance (Bluish, 9300K set on OSD) White Balance (Reddish, 5800K set on OSD) White Balance (sRGB, 6500K set on OSD) X+Y+X+Y+X+Y+0.283+(-) 0.03 0.297+(-) 0.03 0. 326+(-) 0.03 0. 342+(-) 0.03 0.313+(-) 0.03 0. 329 +(-) 0.03

Q7T4-FP71G LCD Monitor Service Guide Alignment Procedure5. Setup input timing , 32 -Gray pattern. To check if there are any abnormal display problems of preset timing modes .No. 1 2 3 4 5 6 7 8 9 10 Check the following preset timings with General pattern: Mode H 720400 @ 70Hz 31.468 640480 @ 60Hz 31.469 640480 @ 75Hz 37.500 800600 @ 60Hz 37.879 800600 @ 75Hz 46.875 1024768 @ 60Hz 48.363 1024768 @ 75Hz 60.023 1152x864 @ 75Hz 67.500 12801024 @ 60Hz 63.981 12801024 @ 75Hz 79.976 V 70.8 59.940 75.000 60.317 75.000 60.004 75.029 75.000 60.020 75.025

6. Checking if the picture is no good, reject this monitor. 7. To check the power consumption by disabling burn-in mode setting 8. To clear user data and program complete DDC data to monitor by IIC bus communication. E. Writing EDID file: 1. Setup a PC with DDC card. 2. Connect PC to monitor with a D-sub signal cable. 3. Please refer to the C212 for the correct EDID file. 4. Runs the writing program to write the EDID file into EEPROM . 5. Read EEPROM data and confirm it to match with the C212 document definition.

F. Command definition :

PC Host will send 0x7C IIC slave address and then following 4 bytes command I2C Send Command Byte1 Byte2 Byte3 Byte4 OK N.A.
