I don't have a real use for this script, so I will not be spending any real time on adding features or fixing it to work with other versions of EDID.

If anyone determines a better test for the "active" monitor, let me know and I'll add it.

If anyone determines a bug in the code, let me know and I'll fix it.

If anyone want support for other versions of EDID (these fields are defined in version 1.3) then you are on your own

I will have a closer look on the non-reporting systems later, to see if the info is burried somewhere else in: CurrentControlSet\Enum\Display


Erik, run the debug version (posted above). It should be immediately obvious where the problem is.

I don't have the info for EDID 2.0, which I guess more recent monitors may support - if anyone has the specifications let me know and I'll have another look.

If you are interested in the documentation you can get the publicly available documents here: http://www.vesa.org/public

I guess you need to pay for the later versions

You will find that older versions of EDID stored a 32 bit serial number at 0x0C - 0x0F - I'll see if I can grab anything sensible from here.
