iEEDID is a lightweight implementation that allows us to obtain the EDID information.
The following EDID standards are supported by iEEDID:
| Standard | Status |
|---|---|
| EDID 1.4: VESA Enhanced Extended Display Identication Data Standard, Release A, Rev. 2 | Implemented |
| DisplayID 1.3: VESA Display Identification Data (DisplayID) Standard, Version 1.3 | In progress... |
| DisplayID 2.0: VESA DisplayID Standard, Version 2.0 | In progress... |
| CTA-861-G: A DTV Profile for Uncompressed High Speed Digital Interfaces | In progress... |
| DI-EXT: VESA Display Information Extension Block Standard, Release A | Implemented |
| LS-EXT: VESA Enhanced EDID Localized String Extension Standard, Release A | In progress... |
| VTB-EXT: VESA Video Timing Block Extension Data Standard, Release A | In progress... |
