Find dead pixels in your monitor

Find dead pixels in your monitor

Right now, at this very second, you're looking at pixels. Sure, you might think you're reading words on a screen, but those words are just thousands of pixels in the millions that make up your screen.

Each pixel is a group of the colors red, green and blue that combine to make any color needed. Unfortunately, pixels are mortal. They can die or get stuck on a color, which can affect the brightness and clarity of your screen.

How do you know if something is wrong with any of your pixels? They tend to look like tiny discolored dots on your screen, and you can quickly find these problem pixels using the super-simple program Dead Pixel Tester.

Since you can't bring dead pixels back to life, you may wonder how this helps you. If you have a warranty for your monitor, it probably covers a certain number of dead pixels. This program can help you get the monitor replaced for free.

There are several different patterns you can use when testing for dead or stuck pixels. The instructions for using the Dead Pixel Tester are available in the pop-up box that remains as long as you are testing for dead or stuck pixels.

Download Instructions

To download the program, go to the Dead Pixel Tester home page and scroll all the way down to the bottom of the information page.

Click on the dark purple download bar that reads: "Download now Built for Windows 7, 8 and 10 (32 and 64bit) operating systems, version 3.00 size 279kb No install required!"  The button will look like this:

When you are finished using Dead Pixel Tester, you will be asked to fill out a short survey. The survey doesn't ask for personal information. You don't have to fill it out, but it helps the software developers to know what works and what doesn't.
