Screen Tester is a straightforward software to help you establish any faulty pixels in your LCD or LED show. Checking for lifeless or stuck pixels is important whenever you get your new handset. A useless pixel is a pixel which is all the time off and shows black. A stuck pixel at all times exhibits pink, inexperienced, blue, or white, and will not change when attempting to show an image.

Screen Tester will show numerous colours in most brightness: white, black, gray, red, green, blue, yellow, magenta, cyan. Tap the display to display the subsequent colour, and examine each pixel rigorously when every color is displayed.
