DisplayTester makes it possible to test almost every aspect of your device's LCD/OLED screen. Using Google Cast it is possible to test the display quality of your TV. It is designed to allow full screen testing also on devices with soft keys (hiding the soft keys in ICS and later, immersive mode in KitKat and later).

    Useful app, but it creates full screen ads on top of other apps. Unacceptable.

    Why would this need my wi-fi information?

    Easy to test real screen size and view angles. Pro version is not needed for everyone, free can do the tests that count for me. I love that it shows what GPU is detected.

    First, to ensure there are no dead or stuck pixels. Second, to ensure that multi touch is working without a hitch.
