About Display Tester 4.21
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).
