Registru: Unable to find Monitor value EDID on Vista RRS feed

  • Question

  • Our pre-Vista Win32 program reported on the active monitor info by looping through:

    HKLM\SYSTEM\CurrentControlSet\Enum\Display

    ... until it found a subkey called "Control". Once found, that indicated the active display and we then read the EDID value in the "\Device Parameters" subkey for the device in order to interpret the needed data.

    But in Vista, the "CONTROL" subkey is no longer found, and the EDID is no longer present in the "Device Parameters" (although there is a BAD_EDID value containing all zeros.

    Is there a way for us to find the same display properties we used to find using the EDID value. Below are the values we used to report by reading and interpreting the EDID:

    Product Code
    Serial Number
    Manufacturer Name
    Manufacturing Date
    Video Input Mode
    Feature Support Capabilities

    Thanks for any advice!
