The following just happened today:
When I turn on my Canon 60D, the Quick Control screen is shown on the LCD monitor, for the length of the auto power off time. Then power turns off.
Similarly, when I take a picture, the image appears on the LCD for the length of the image review time, and then the Quick Control screen appears. The same when I review images.
This is very annoying. Is there any setting I can use to revert to the standard behavior (when the LCD should be black)?
