BERLIN: When you buy a new monitor, the first thing you should do is check the picture carefully and report any noticeable pixel errors to the seller.

Even if a tiny dot on your screen catches your eye in the weeks and months after you bought it, there are still many options, and you may be able to get a replacement through the warranty, the guarantee or even good will.

But one pixel on an older screen starts displaying the wrong colour, then you have no choice but to try and fix it yourself. That’s where programs such as PixelHealer come in handy. It’s free, easy to run and works with LCD and TFT displays.

You can either install the program or alternatively use the portable version, which just needs to be double-clicked on once you've downloaded it.

Using the mouse you then move the coloured square into the monitor area with the pixel error and click "start flashing."

After that the square quickly change through the selected RGB colours. Flashing colours in this way can cause hanging pixels to recover and start working properly again. However, there’s no guarantee of success. If the pixel in question truly is broken and unresponsive, there’s nothing that PixelHealer and the like can do.

You can also check for pixel errors on websites like, which don't require any installation.

Simply make sure that there’s no dust or smears on the display and then start the test. While the colours change between white, black, green, red and so on, you can scan your screen for pixel errors. – dpa
