How to Use White Test Screen for Dead Pixel Detection?

Our devices are essential parts of our lives, serving us for work, entertainment, and communication. With such heavy reliance on these screens, it’s vital to ensure they function flawlessly. One common issue that can disrupt our experience is dead pixels. This comprehensive guide will teach you how to use white test screen to detect dead pixels and ensure your device’s display is in perfect condition.

What is a Dead Pixel?

A dead pixel is a pixel on a screen that doesn’t display the correct color or any color at all. Unlike other pixels that change color based on the image or video displayed, dead pixels remain static. Dead pixels can be particularly bothersome because they are often visible against a uniform background, such as a white screen. They can be black (completely unlit) or stuck on a single color.

Importance of Detecting Dead Pixels

Detecting dead pixels is crucial for several reasons:

1. Visual Quality: Dead pixels can be distracting, especially on high-resolution displays.
