Display Tester is a mobile application developed by Braintrapp that allows users to test various aspects of their device’s display. The app has been downloaded over a million times and is available for both Android and iOS.

One of the main features of the Display Tester is its ability to test for dead pixels on the screen. The programme provides a spectrum of colours that users may cycle through to check for any pixels that are not operating properly. If the screen on your smartphone is malfunctioning, this might help you pinpoint the problem and decide whether to get a replacement or repair.

In addition to dead pixel testing, Display Tester also provides a number of additional display tests, including colour and contrast tests, gamma calibration, and viewing angle tests. The results of these tests can be used by the user to fine-tune the display settings of their device.

Another important feature of the Display Tester is its ability to evaluate the device’s multi-touch capability. This may be especially advantageous for users that depend extensively on touch-based input, such as gamers or graphic artists.

But some of Display Tester’s more complex capabilities may require technical expertise to properly comprehend and apply. The testing procedure may be difficult, but the software includes a number of useful instructions and tutorials to help users through it.

If you want to test and improve your device’s display, Display Tester is your best option. While more advanced features may require some technical know-how, this app is great for beginners and pros alike thanks to its straightforward interface and straightforward operation.
