B4.2.4 Monitors - Windows Experience B4.2.4.1 Color monitor is DDC2B-compliant and supports EDID 1.3 data structure
A monitor must be compliant with VESA Enhanced Extended Display Data Channel Standard (E-DDC), Version 1, Level 2B protocols (DDC2B), which defines the communications channel between the display and host system. A monitor must assume multiple I2C-compliant devices exist on the communications bus, and as such, a monitor must not impede the use of the I2C bus in any way. A monitor designed for, or included with, a PC 2001 system must not issue DDC1 transactions.
The monitor also must transmit an EDID structure containing unique ID Manufacturer Name and ID Product Code identifiers, plus all required fields, as defined in Section 3 of VESA Enhanced Extended Display Identification Data Standard (E-EDID), Release A.
For analog CRTs, EDID content must indicate at least one VESA mode at 75 Hz, or better, for each resolution supported.
