Our dead pixel test above eases the process for you, allowing your web browser to go full screen and to dispay unified colors on your monitor. An consistently black pixel can be interpreted as a dead pixel, while a pixel stuck on a single color is generally referred to as a stuck pixel. Generally, the preferred method is to display unified colors on your full screen to check for any odd pixel. There is no secret, running a dead pixel test on your screen requires you to carefully inspect it inch-by-inch.

You may find more information on the topic on our What is a dead pixel page. For instance, if both the blue and the green one are stuck, your pixel will be stuck on light blue.

One, two, or all three sub pixels might be stuck and can’t turn off anymore.

Three dead sub pixels on a same pixel will result in a black dot on your screen, whatever it displays.

It won’t have any problem with yellow, for instance (green + red), but show black if it needs to display pink (blue + red). For instance, if the dead sub pixel is the blue one, the pixel will remain black only on colors with some amount of blue in them.

One or two dead sub pixel might result in your pixel remaining black only on some colors.

Is thus necessary to distinguish several cases: Sub pixels can either be completely broken so that they don't light up anymore, or they can be stuck and permanently lit. One, two and even all three of them can be damaged. Once again, in reality, pixel malfunctions are caused by sub pixels defects. Sometimes, it will occurs that pixels can malfunction. If only the red sub pixel and the blue one are lit to full power, your pixel will show pink… What are dead pixels, what are stuck pixels? If all are turned off, it will display black. For instance, if all three sub pixels are lit to full power, your pixel will show white. Each of them can light up to a certain percentage to allow your pixel to display every color it needs. In reality, a pixel is made of three sub pixels - one red, one green and one blue.
