If you’re looking for more real estate on your desktop or laptop to work on, but you don’t want to invest in a larger or extra monitor, why not make use of what you already have? If you own an Android tablet or a smartphone, you’re in luck. The folks over at Shape Services have come up with an app to let you turn your Android device into an extension of your main display. With your Android device as a second screen, you can make it drag windows onto it so it won’t clutter up your main screen. By using software like instant messengers or widgets on the Android extension of the screen, you free up your main display for important stuff so you’ll have more space to work on. If you don’t want to use your phone as a screen extension, you can even use it to mirror what’s on the main display. This functionality will allow you to check on what’s displaying on your monitor while you’re away from it. So you can check on the progress of a file being downloaded or a scene being rendered while you’re downstairs in the kitchen preparing dinner. iDisplay works on both Windows and Mac, it costs only $1.99 and can be purchased here.
