Summary : Adjustment component 480i/1080i and RGB

1080p is Gain and Black levelsetting at Analog
to Digital converter, and compensate the RGB
deviation 

O 

Using instrument

- Adjustment remocon, 801GF(802B, 802F, 802R) or

MSPG925FA pattern generator (It can output 480i/1080i
horizontal 100% color bar pattern signal, and its output
level must setting 0.7V±0.1V p-p correctly) 

<Pic.4 Adjustment pattern : 480i / 1080p 60Hz Pattern >

* You must make it sure its resolution and pattern cause every

instrument can have different setting

O 

Adjustment method 480i Comp1, Adjust 1080p
Comp1/RGB (Factory adjustment)

• ADC 480i Component1 adjustment
- Check connection of Component1 
- MSPG-925FA Ë Model: 209, Pattern 65
• Set Component 480i mode and 100% Horizontal Color

Bar Pattern(HozTV31Bar), then set TV set to
Component1 mode and its screen to “NORMAL”   

• ADC 1080p Component1 / RGB adjustment 

- Check connection both of Component1 and RGB 
- MSPG-925FA  Model: 225, Pattern 65

• Set Component 1080p mode and 100% Horizontal Color

Bar Pattern(HozTV31Bar), then set TV set to
Component1 mode and its screen to “NORMAL”  

• After get each the signal, wait more a second and enter

the  “IN-START” with press IN-START key of Service
remocon. After then select “7. External ADC” with
navigator button and press “Enter”.  

• After Then Press key of Service remocon “Right

Arrow(VOL+)” 

• You can see “ADC Component1 Success” 
• Component1 1080p, RGB 1080p Adjust is same

method. 

• Component 1080p Adjustment in Component1 input

mode

• RGB 1080p adjustment in RGB input mode
• If you success RGB 1080p Adjust. You can see “ADC

RGB-DTV Success” 

O 

Summary

• It is established in VESA, for communication between

PC and Monitor without order from user for building user
condition. It helps to make easily use realize “Plug and
Play” function.  

• For EDID data write, we use DDC2B protocol. 

O 

Auto Download

• After enter Service Mode by pushing “ADJ” key,
• Enter EDID D/L mode.
• Enter “START” by pushing “OK” key. 

Caution: - Never connect HDMI & D-sub Cable when the user

downloading . 

- Use the proper cables below for EDID Writing.

Manual Download  

• Write HDMI EDID data

- Using instruments 

=> Jig. (PC Serial to D-Sub connection) for PC, DDC

adjustment. 

=> S/W for DDC recording (EDID data write and

read) 

=> D-sub jack 
=> Additional HDMI cable connection Jig. 

- Preparing and setting. 

=> Set instruments and Jig. Like pic.5), then turn on

PC and Jig.  

=> Operate DDC write S/W (EDID write & read)
=> It will operate in the DOS mode. 

Pic.3) For write EDID data, setting Jig and another instruments. 

• EDID data for LJ91D Chassis (Model name = LG TV)
- HDMI-1 EDID table (0x3D, 0x2C) 

- HDM2 EDID table (0x3D, 0x1C) 

- HDMI-3 EDID table (0x3D, 0x0C)  

- Analog (RGB) EDID table (0x9B, 0x25)
