VESA ENHANCED EXTENDED DISPLAY IDENTIFICATION DATA STANDARD
(Defines EDID Structure Version 1, Revision 4)
2.1.5 EDID 1.4
EDID structure 1.4 is introduced in this document. EDID structure 1.4 adds support for Consumer
Electronic Products (Model Year and Aspect Ratio) and PC Products (CVT, Established Timings III,
Additional Video Interfaces, Expanded Display Range Limits, optional Product Features and Timing
Mode Priorities). Certain Display Descriptors (formally known as Monitor Descriptors) that were
mandatory in EDID 1.3 are now optional.
EDID 1.4 is based on the same core as all other EDID 1.x structures. EDID 1.4 is the new baseline for
EDID data structures and is strongly recommended for all new designs. However, there are a few
incompatible data fields in EDID 1.4 that were changed to support emerging industry requirements.
Structure 1.4 is a superset of structure 1.3. The main difference between the two is that 1.4 allows the
Display Range Limits descriptor to define support for CVT, and certain display descriptors mandated in
EDID 1.3 are now optional. Some additional changes have been included to provide support for DTV
products.
