/*
- * Note that DDC1 does not define any method for returning blocks beyond
- * the first. DDC2 does, but the original implementation would only ever
- * read the first block. If you want to read and parse all blocks, use
- * xf86DoEEDID().
+ * A note on terminology. DDC1 is the original dumb serial protocol, and
+ * can only do up to 128 bytes of EDID. DDC2 is I2C-encapsulated and
+ * introduces extension blocks. EDID is the old display identification
+ * block, DisplayID is the new one.
