If you have a BlackBerry Playbook and want to create your own wallpaper, make sure that you know the screen size of your playbook.
On the specification sheet, said that the BlackBerry Playbook has a 1024 x 600 screen size. If you have a wallpaper with 1024 x 600 size, it will be displayed perfectly. but, when the device is positioned to portrait mode, the display size will be changed and your wallpaper will not perfectly displayed.
In fact we are required to make a wallpaper with size 1024 × 1024 pixels so that we can display the wallpaper very well in various positions, either landscape or portrait. Maybe the picture below explains enough about the size of wallpaper that can be used for your Playbook.
