C1 tethering with Canon 1dsIII/ image review on camera screen

[G_Allen]

I had a quick question about tethering with C1. When tethering with
the P65+, I can review the image/check histogram on the back's screen
(as well as on the computer, obviously).

Is is possible to do this with the Canons? When I tether with my 1ds
III, I can't review the image on the camera's screen when I'm tethered.

Thanks for the help!

Cheers
