HDCP-Canon 5D

Can anyone one confirm if the Canon 5D Mark II HDMI output requires a display to be HDCP compliant or not for 1080, instead of just 480, output?

I've asked Canon technical support and their answer was that they do not know. I can't imagine HDCP compatibility would be required for 1080 output out of any camera, but we've tested 4 different brands without HDCP and they all do not work.

When testing HDCP compliant monitors with this camera we have no problems, but I still feel like this must just be coincidence because I can't imagine why a content protection scheme for consumer media would be implemented in a camera's HDMI output.

If anyone has any insight on this that would be greatly appreciated.

Some more info: all of the units without HDCP have DVI inputs, we use HDMI to DVI cables for this purpose. The two with HDCP have HDMI inputs. This could be the reason for the incompatibility as well, but that too would be surprising. Anyone using the Mark II, and getting 1080 output (not while recording of course), with a DVI equipped monitor?

In the interest of maybe providing useful information to others that may come across problems with displays that don't work in 1080 with the Canon 5D Mark II, here is the issue:

-Has nothing to do with HDCP compliance, not required, so that is good.
-If you have a display that does not work at 1080 in the live view mode with the Canon 5D Mark II it is probably attributable to one of two things: Native preferred timing not set to 1920x1080i in monitor's EDID or that the display type is listed as RGB color and default color space is listed as sRGB in the monitor's EDID.

The 1080 HDMI output from the Mark II is YCbCr so if your display's EDID indicates that the color space/display type are RGB the camera will default down to 480p RGB output. Modifying the displays EDID accordingly solves the compatibility issue.

Could you do it using the Pheonix and MonInfo softwares?

I just bought a new Acer monitor and am having this same problem. Is there any solution/tutorial to provide details on how to make this work?
