1. What is Pixel Tester?
You want to check if your portable Mac or your screens or LCD displays have any dead pixels? You want to buy a second-hand portable Mac or LCD display but you want to check it first not to buy a defective one? You have multiple screens connected on the same Mac and want to check all of them without changing the connections?
Then Pixel Tester is what you need!
Pixel Tester helps you to detect any dead pixel on your screens or LCD displays.
- You can test all possible and existing colors on your screen simply by moving the mouse, which is fun, simple and fast.
- You can in particular test pure red, pure green and pure blue by moving the mouse at the bottom of the screen, and pure white by moving it at the top of the screen.
- You can test pure black at the end of the test.
- It uses several patterns to help you to detect dead pixels more easily.
- It supports multiple monitors and asks you at launch which one you want to test.
- It doesn't need any installation which makes it very easy to use.
- It is available in Dutch, English, French, German, Italian, Turkish and many other languages.

Remember to read the Conditions of Use, Publication and Distribution before installing and using our Applications.
3. How to install it?
No particular installation is required. Once you've downloaded the ".dmg" package from our website, it should uncompress automatically (in your "Downloads" folder or on your Desktop). If it does not, then you can double-click on it to uncompress it.
Then you just have to move the created folder into your "Applications" folder (or any other location) and double-click on the Application to launch it.
Particular case of MacOS 11 Big Sur:
Under MacOS 11 Big Sur, if you're launching the Application for the first time, MacOS' GateKeeper (which you can configure in the "System Preferences") will refuse to launch it because you've not downloaded it from the Mac App Store (but from our website). In this case, instead of double-clicking on it, all you have to do is to right-click on the Application's icon, and then select the "Open" menu. A message will appear in which you'll be able to confirm that you want to launch the Application (even if it was not downloaded from the Mac App Store from an Identified Developper).
NB: We're not distributing our Applications through the Mac App Store, because Apple's fees policy on the Mac App Store is not financially respectful of developers and small and medium companies, and consequently, at the end, of customers.
4. How to uninstall it?
There should be no reason to do this. ;-)
However, if you really want, then you just have to throw the Application into the trash, and that's all.
5. How to use it?
Launch the Application and click on the first window, which tells you what to do.
Then move the mouse on the screen to change its color. If you look carefully at the screen it should help you to see if there are dead pixels, which are pixels that can't emit or partially emit colors.
If you click and continue to move the mouse, different grids will be added, which should help you too (a vertical grid, an horizontal grid and a crossed grid).
If you see something suspicious, like dots or line breaks on the grids, then you probably have dead pixels.
The last black screen turns off all pixels so that you can check that none of them remains alight.
