    I'm working on a script that will do something (what is not important for the
    purposes of this discussion) based on the attached monitor's make and model
    number. Neither the Windows driver nor WMI provide this information, so I'm
    using the EDID information. So far so good. I downloaded a pdf from
    that describes the EDID standard format. Using this I'm able to extract lots
    of information including screen size, supported resolutions, serial number,
    etc. Still no problem.

    Among the EDID data I am able to extract, there is a "manufacturer ID code"
    and a "product ID code." Both are 2-byte hexadecimal numbers. For example on
    my Samsung SyncMaster 320PX the manufacturer ID code is 2D4C and the product
    ID code is 027B. That brings me to my questions.

    It seems logical to assume that all Samsung products will have the same
    manufacturer ID code: 2D4C. Can anyone say for sure if this is true?
    Similarly can we say that the same model numbers will have the same product
    ID codes (e.g. a 320PX will always be 027B)? Also if the previous statements
    are true, then is there a publicly available cross-reference chart which maps
    these values?

  2. Try looking at your monitor in Windows device manager - what is the hardware ID? is it alike 2d4c&027b?
