RTD2555LH embedded 16.5KSRAM dynamically stores OSD command and fonts, compatible advanced color
control features.
2.) EEPROM:
We use 24C16 EEPROM to store monitor user data and user preset timings. There are 16 user timing modes
are automatically saved in it. Each timing mode is allocated with 22 bytes of memory space for information such
as Sync frequencies, pol
arities… etc. PC can access the EEPROM data indirectly through the SDA and SCL
channels of DVI and D-sub (IIC communication). The digital and analog DDC data are stored in two 24C02s
EEPROM.
