HDMI Protocol Test Commands

EDID/DIDT
Command supported?: N
Reads the EDID and provides the information to the user. EDID? returns the binary EDID as-is, where DIDT? returns a
parsed version that describes some useful details about the EDID.
Examples:
EDID? (reads the EDID from the first HDMI port and returns the binary data)
DIDT? 2 (reads the EDID from the third HDMI port and returns details. Ports are 0-3.)
Header is valid. All checksums valid. EDID Version 1.3
