Pixel Réa: The Easy Way to Fix Dead Pixels on LCD/LED Screens

Posted by

Do you have dead pixels on your LCD or LED screen? If so, you’re not alone. Dead pixels are a common problem, but they can be unsightly and annoying. Luckily, there’s a free software program called Pixel Réa that can help you find and fix dead pixels.

Pixel Réa is a simple yet effective software that helps you detect and potentially repair dead pixels on your LCD or LED monitor.

What are dead pixels?

A dead pixel is a pixel on your screen that doesn’t work. It can be black, white, or a different colour.

Over time, the visual quality of your screen can be impacted by dead pixels, which are black or stuck in one colour.

What Causes Dead Pixels?

Images are displayed on LCD and LED panels by changing the colour of thousands of individual light-emitting diodes.

Various factors, such as manufacturing defects, physical damage, or prolonged exposure to extreme temperatures, can cause dead pixels.

With extended use, some of these diodes may malfunction, leading to the appearance of “dead pixels” that either appear black or get stuck displaying a single colour.


Detecting Dead Pixels with Pixel Réa

Pixel Réa is a free software program that can help you find dead pixels on your screen. Download it from the official website and install the program.

Once the program is installed, open it and it displays two options: dead pixel detection and burned area detection.

Click “Run” under dead pixel detection to start a full-screen test showing red, green, and blue colors. Any abnormal colouration on the screen can identify dead pixels. Exit the test by pressing the Escape key.

How to fix dead pixels with Pixel Réa

The app’s colour-cycling feature may offer a potential solution for pixels stuck showing only one colour, which are often permanent. Rapidly changing screen colours during the repair process may jostle pixels loose, restoring their function.

To do this, click on the “Repair” button, then choose either Repair 1 or 2 or 3 and hit the “Run” button. The Windows app will then cycle through a series of different colours on your screen. This process can take several minutes, but it may fix your dead pixels.
