I2C bus 2 is typically used to detect a DVI monitor via a DVI connector. However, for devices with a DVI-I connector, VGA signals come out of the connector as well. What this means is that I2C bus 2 also has to be used to detect a VGA monitor, in addition to I2C bus 1. Furthermore, EDID obtained from the monitor via I2C bus will be used to determine whether or not it is an analog type (i.e., VGA monitor).
