Even if those two steps didn't work, following the steps to turn off the Zoom accessibility feature should correct the zoomed in display. And for those who cured the issue with the two steps above, this will help keep you from getting the iPad stuck in zoom mode in the future.
First we need to go into the iPad's settings. If you are unfamiliar with getting into the iPad's settings, you can do so by tapping the icon that looks like gears. It can be a good idea to make sure this icon is on your iPad's dock if you haven't already done so. (Help on Opening the iPad's Settings)
Next, choose the General settings. This about midway down the screen just under Picture Frame.
In the general settings, you'll need to scroll down a little bit until you see "Accessibility" near the bottom. Tapping it will give you the different accessibility settings.
There are two things to do here. First, check to the right of where it says "Zoom". If this feature is on, you can tap the zoom feature to get to a screen that allows you to turn it off. (If your iPad is currently zoomed in, turning this feature off will zoom it back out.)
The second thing we need to do is check the home button settings. Back at the accessibility settings, check the bottom setting labeled "Triple-click Home". If this is set to Zoom, you can tap the Triple-click Home setting to reach a screen that will allow you to configure triple clicks. It's usually best to turn this feature off unless you need accessibility features.
