550D live histogram while shooting video?

Hey Guys
I use the 550D as a spare static camera for shooting video.
I cant bring up a live histogram while shooting video anymore (Yet can on 600D and 5D iii).
Now either I'm going crazy here and it never did it (And I just never noticed it before as I sometimes also run Magic lantern on it) or Ive done something to the settings?
Any thoughts?


Thanks in advance.
