In line 1887 of source file miniport.c, if changing the
dwMMDMMSupportType from MMDMM_SUPPORT_XDDM_PARITY to
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.

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.
