The back display on my PowerShot SX60 is only showing me a "portrait" view of whatever I'm shooting and not filling the whole screen (this is while I'm setting up a shot, not displaying an image.) In other words, there's black on either side of whatever scene I'm looking at on the display. How doI fix this? It was fine up until today when I was testing it out, but I think I pressed something and now can't get the display corrected. This is the first Canon I've had with a flip-out viewfinder so I don't know how to correct the problem.
