Canon 7d Display Invert

[AdamC]

I don't know if anyone else has this problem but, I've been trying to mount an onboard monitor upside down but it lacks a function to do so.  The 7d can use upside down view mode but that's only if you invert the camera.  I'd like a way to make the screen and the image HDMI sends out to be flipped upside down 180° and even mirrored could be helpful.

As I had said, I want to use the camera right side up with an upside down monitor.  That only flips the menus.  The WHOLE IMAGE needs to be flipped.
