7.2 Adjustment of Component.* Required Equipments- Remote controller for adjustment- 802F Pattern Generator, Master (MSPG-925FA), etc- MSPG-925FA Pattern Generator(Which has 720p@60Hz YPbPr signal : 100% ColorBar Pattern shown in Fig. 3 )=> Model: 217 / Pattern: 65- It is very import to use correct adjustment pattern likeFig.3.a. Within the pattern, color sequence should be aligned: White-Yellow-Cyan-Green-Magenta-Red-BLUE-BLACK(If color sequence is reversed (Black -> …-> White),reverse the pattern with REV key, when using Masterpattern generator like MSPG-925)b. If Minimum Black Level and/or Maximum White Levelis not correct, Do select 100% Color Bar Pattern.7.3 Adjustment of RGB* Required Equipments- Remote controller for adjustment- 802F Pattern Generator, Master (MSPG-925FA), etc- MSPG-925FA Pattern Generator(Which has XGA [1024*768] 60Hz PC Format outputsignal : 100% Color Bar Pattern shown in Fig. 4 )- It is very import to use correct adjustment pattern likeFig. 4.a. Within the pattern, color sequence should be aligned: White-Yellow-Cyan-Green-Magenta-Red-BLUE-BLACK(If color sequence is reversed (Black -> …-> White),reverse the pattern with REV key, when using Masterpattern generator like MSPG-925)b. If Minimum Black Level and/or Maximum White Levelis not correct, Do select 100% Color Bar Pattern(Fig. 3)7.2.1 Method of Auto Component Color Balance1) Input the Component 720p 100% Color Bar(MSPG-925FA model:217, pattern:65) signal into Component.(MH : component 1 )2) Set the PSM to Dynamic mode in the Picture menu3) Press the INSTART key on R/C for adjustment4) Press the (Vol. +) key to operate the set, then itbecomes automatically5) Auto-RGB OK means the adjustment is completed(Fig. 4)7.3.1 Method of Auto RGB Color Balance1) Input the PC 1024x768 @ 60Hz with 100% color barpattern like Fig.4. into RGB.(Ex. MSPG-925FA, model:60, pattern:65)2) Set the PSM to Dynamic mode in Picture menu3) Press the INSTART key on R/C for adjustment4) Press the (Vol. +) key operate To set , then itbecomes automatically5) Auto-RGB OK means adjustment is completedCopyright © 2007 LG Electronics.

8. White Balance* Caution : Before White-balance, the AV ADC should be done.=> Notice- Do the white balance adjustment under the 10LUX- Before white balance, press the In-start key 2times and dothe reset like Fig.5- Use the Torino inner pattern(216 gray pattern)- To enter White-balance mode,press the IN-START key2times.* Caution : - System control RS-232 Host should be "PC" foradjustment.White Balance(Hex)Color Temp.
