(Center). The exact brightness values are confirmed by the checking-regulations of different customers and different models. Ⅱ. Steps of white-balance adjustment for LCD:(Take 19” HP LCD for example) 1. Required instruments: Chroma7120、Chroma2325（BGA265A） 。 2. First connect the instruments together and turn on the LCD power, then warm up for 30 minutes under full white screen mode. - Page 42 19" LCD Color Monitor HP VS19E d) Test white-balance again after Auto Level. Adjustment with hand is necessary if it is beyond the specs just the same. e) Select 7x00 item to adjust cool color-temperature and select 6x00 to adjust warm color- temperature. It can reach to the best effect through adjusting R/G/B value if it inclines to green or blue.
