The iPad is a great little device, there’s no doubt about it. But you’ve gotta know that when you take features, such as apps for the iPhone and iPod, and try to simply just switch them over to another device, such as the iPad, there’s bound to be some kinks encountered along the way. One such kink is the fact that because so many of these apps were created to be displayed on the smaller screen of the iPhone and iPod Touch, when viewing them on the iPad, they are much smaller, and take up only a fraction of the screen. Luckily, when Apple came out with the iPad, they did foresee this problem, and they created a way to view iPad apps in full screen mode.
To get started viewing your apps in full screen mode, tap on the app to open it. If the app was created specifically for the iPad, and was purchased or downloaded after you bought your iPad, the app will most likely automatically open up in full screen mode. However, if the app was downloaded for the iPhone or the iPod Touch, and you now want to use them on your iPad, the app will most likely open up in the center of the screen in a small window.
To fix this, look in the bottom right corner of the screen. There you’ll see a button that says “2X.” Simply tap that and the app will enlarge to full screen mode. The button at the bottom of the screen however, will change to “1X.” So, if you ever want to go back to viewing the smaller version of your apps, you can tap that button and it will change back.
