How to Change the Brightness and Wallpaper Settings on Your iPad
There are two visual settings that fall together as one category in the iPad's Settings window: Brightness & Wallpaper. Adjusting these settings can make your interaction with an iPad easy on the eyes and easy on the battery power.
Especially when you're using iPad as an e-book reader, you may find a little less brightness in the display reduces strain on your eyes. Also, reducing the brightness can save a little on your iPad's battery life.
To modify the brightness setting, follow these steps:
Tap the Settings icon on the Home screen.
In the Settings dialog, tap Brightness & Wallpaper.
To control brightness manually, tap the Auto-Brightness On/Off button to turn it off.
Tap and drag the Brightness slider to the right to make the screen brighter or to the left to make it dimmer.
Press the Home button to close the Settings dialog.
If glare from the screen is a problem for you, consider getting a screen protector. This thin film not only protects your screen from damage but can also reduce glare.
Changing the wallpaper
Just as your desktop computer or laptop has the ability to display a pretty picture or pattern as a desktop background, your iPad can display an image on the Home screen.
The picture of a mountain lake that's the default iPad image may be pretty, but it's also pretty dark. Choosing different wallpaper may help you to see all the icons on your Home screen, or just allow you to display an image that appeals to your artistic sensibilities.
To change the wallpaper, do this:
Tap the Settings icon on the Home screen, and then, in the Settings dialog, tap Brightness & Wallpaper.
In the Brightness & Wallpaper settings that appear, tap the arrow to the right of the Wallpaper section.
When options appear, tap Wallpaper to display all the built-in wallpaper images.
Tap a wallpaper selection in the Wallpaper dialog to set it.
Tap the Set Home Screen button.
Alternatively, you can tap Set Lock Screen to use the image only when the screen is locked, or you can tap Set Both to use the image for both the wallpaper and when the screen is locked. If you want to go back to the other wallpapers, tap Cancel.
Tap the Home button and you return to your Home screen with the new wallpaper set as the background.
You can also use your own picture for your wallpaper. In Step 3, instead of choosing Wallpaper, tap Saved Photos or choose a photo library to browse your saved photos, select the picture you want to assign, and then resume with Step 5 above to apply that screen to your iPad.
