ABSTRACT:
A display monitor for a common display data channel uses a DDC access switch to separate the common display data channel, so that regardless of whether the display monitor is powered on or off, a personal computer can access the Extended Display Identification Data (EDID) in the EEPROM, and the low-level voltage of an MCU in the display monitor won't interfere in the access between the personal computer and the EEPROM. When the power of the display monitor is turned on, the DDC access switch closes so that the MCU can access the EDID in the EEPROM.
