ERROR_MONITOR_INVALID_MANUFACTURE_DATE
ERROR_MONITOR_INVALID_MANUFACTURE_DATE means that the date fields in the EDID Vendor and Product ID area cannot be interpreted according to the expected encoding. This is a descriptor-data problem, not a comparison with the computer's current date or with a Windows driver installation date.
Fields to inspect
In EDID 1.4, byte 10h is the manufacture week or the FFh model-year flag. Byte 11h stores a year or model-year offset from 1990. The standard reserves some values, so a random or truncated pair can be rejected even if the monitor name and preferred timing are otherwise readable.
Useful comparison
Compare bytes 10h and 11h in a fresh raw capture with a known-good capture for the same monitor. Do not rewrite only the date fields without validating the base-block checksum afterward.

Microsoft: obtain the raw 128-byte E-EDID block
