    In line 1887 of source file miniport.c, if changing the
    MMDMM_SUPPORT_TEST, it seems that the built driver will light only
    one of two pixel in VGA monitor and the rest be black. If changed
    back to MMDMM_SUPPORT_XDDM_PARITY, then everything will be OK. I am
    using a Radeon 8500 with 64M DDR installed.

    Anyone encounter such probelm?

    After some tracing work, It seems all of the 4 source mode IDs used in
    the VidPN test path are not included in correspoding XDDM version. Why
    DDK provide VidPN test in this way?

    It turn out to a document fault in WDK 6000. The code path of
    MMDMM_SUPPORT_TEST follow the document in WDK 6000, but that part has
    been updated in WDK 6001.
