Decoding a DELL Monitor Serial Number using EDID

Hi All,

I am recovering the EDID of all monitors in my enterprise - the Dell Monitor EDID is posing a bit of a problem.

Decoding the Hex value in "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Display\wmi-lookup\wmi-lookup\Device Parameters" provides me most of the PPID but NOT all of it.

I would like to know how to retrieve the rest of it, and whether or not it has any importance (ie. are the results worth the efforts )

For example

PPID on the Monitor is CN-0V6WMN-72872-14L-0RYI

PPID extracted from registry is  V6WMN14L0RYI

So, as you can see, I am missing the leading CN-0. I believe that this is not important.

V6WMN - this corresponds to the Part-Number, and allows me to identify the correct model.

I am also missing the 72872.....and I do not know where this can be found in the registry, or what it corresponds to. It does not appear to be unique to each SN, but these 5 digits do seem to vary according to something (not strictly related to the model).

14L - this is a representation of the manufacture date.

0RYI - I do not know what this means, and probably don't need to.


Thanks

Jif
