Geoffrey McRae 1ce446f97a [idd] stop using IddCxMonitorUpdateModes(2)
While it would make much more sense to use these then a full replug to
change modes, Microsoft have not properly implemented the API to clear
the cached monitor mode states internally, making these calls useless.

Revert to just replugging the device on mode change
