HP notebook wont play IronMan

[EJtheBBC]

I can play Ironman just fine on the HP DV7-1145nr display, but when I try to use an External Monitor I get a "The content is protected. The content is not allowed to play in the current display mode." error.
I'm trying to send this signal via HDMI to an LCD with 720p or an HD Rear Proj with 1080i. Either way, I set-up the TV as the only monitor and still get this error. Is it because I'm trying to downgrade the signal from 1080p?
Any help would be appreciated. Thx Ed

Glad the QP instructions helped you guys. Wish HP would learn how to use them - they're telling people all kinds of incorrect ways to fix a simple problem.

Ed,
Usually you get this problem when you're setting up your system in cloned or dual-view display mode. Even though you've indicated that your external is the only monitor, you haven't said whether or not your PC is set to use your external as its primary display. If not, that's your problem - you have to set it as the primary PC display.

Problems can also occur if your system monitor (in this case your external) is in full color mode - normally when a system starts BD playback it automatically resets the desktop colors to 16. If your external is set as the PC's primary display and isn't doing that, it could be a contributing factor.

Another possibility is the HDMI cable you're using - if it's an older HDMI type cable (1.1 or 1.2) and it's HDMI-DVI or if it's a pre-2005 HDMI cable, it will cause a content protection error as well.

You also need to remember that your external display has its own HDMI input settings, and most systems aren't set to automatically sense an HDMI cable connection - it has to be turned on. The way to determine this of course is whether or not you can view your PC desktop on your external.
