Some LCD displays present dead pixels which, depending on the manufacturer policy regarding faulty pixels, can be a reason to ask for a replacement. Pixel Tester is a simple Mac app that allows you to quickly test all connected displays, in order to identify pixels that do not work properly.

Effortless to use software solutions for instantly identifying dead screen pixels

The Pixel Tester application comes with a streamlined workflow that makes the testing process extremely easy. Start by selecting the display you want to test, and then move your cursor around to change the pattern displayed on the screen.

Depending on the display area in which you place the mouse, Pixel Tester shows different colors and patterns: pure red / blue / green when the pointer is in the bottom screen area, and pure white for the top of the screen.

Features multiple test patterns for your screen and can work with multiple displays

To make sure you are able to identify all dead pixels, Pixel Tester comes packed with a collection of  patterns designed to make them visible. Moreover, you have the opportunity to test various displays with minimal effort: the app recognizes all connected devices and allows you to choose the one on which you want to perform the test.

User friendly display testing utility featuring simple tools for visualizing dead pixels

Pixel Tester offers you the possibility to quickly identify dead pixels present on your screen with minimal effort: all you have to do is launch the application and move the mouse pointer to quickly switch between various patterns designed to cover your entire screen. Since the patterns have a special design, you will instantly be able to quickly see if there are any issues.
