been thru 290.36 also and still nothing...
not even 3d via hdmi is working...
though gt540m states it support 3d displays yet, not detecting my lg 3d tv connected via hdmi...
and powerdvd still runs via onboard intel hd graphics....
i also informed nvidia with this matter and their answer to this is, that nvidia optimus is software dependent trigger thus powerdvd is the software concerns that's why it doesn't trigger optimus to run on nvidia graphics....
even tried to turn off any power saving and still nothing...
