To give you the answer you are looking for is in a nutshell, no. When you plug in the HDMI cable to a tv or capture card, the resolution will cut to 1440×900. Even then the onscreen info shows up as well.

The 7D however, having 2 sensors, will show full 1080p on screen when not recording to the memory card. You will still see the crop box unless you cycle through the display options to turn it off.

There is a collection of videos on vimeo from a wedding videographer that just switched to 7Ds and T2is for his cameras. In that collection he demoed the HMDI capabilities and compared the T2i and 7D. https://vimeo.com/channels/jjdslr. Lot of good info.
