I think the OP means they 'zoomed in' on the LCD and saw that it was out of focus.

Accuracy of the autofocus depends on quite a few factors - and the AF area is often bigger than the AF point in the viewfinder so if it finds something of higher contrast than the stubject you want to take a picture of then it will focus on that instead.
