Well, that's way to much user interaction for this topic cause there is no way
to ask a TV if the picture looks ok other than asking the user.

I'm going to supmit the patch to drm-fixes (with a bit higher limit) so it
should end up in 3.15 together with the patch that created the problem in the
first place.
