Dead Pixel Test
Small spots on the display that do not display correctly are called dead pixels. They show up as black, white, or colored dots and never change when the surrounding pixels change state. Usually, these are caused by defects in the manufacturing process or prolonged use of the display. A dead pixel can be irritating to deal with in a new gadget since it just kills the view. Dead Pixel Test is a utility that allows detecting and managing dead pixels on your screen. Now, you can check your screen for free online without installing software.
What is a Dead Pixel?
A dead pixel is, in general terms, a pixel of the screen which does not work the right way. While most of the pixels on a display are supposed to switch colors and brightness depending on what is shown, dead pixels appear fixed in color. They can take on an appearance such as:
Black pixels: When the pixel is completely dead it emits no light at all.
White pixels: The pixel remains in the “on” state without changing according to the image.
Colored pixels: The sub-pixels are likely malfunctioning to get it stuck in any color, either red, green, or blue.
Dead pixels usually come into LCDs, which are Liquid Crystal Displays, and OLEDs, meaning Organic Light Emitting Diode. They will affect your smartphone, laptop, computer monitor, and even your television.
Why Check for Dead Pixels?
Dead pixels can affect both performance and visual quality on your screen. Minor one or two dead pixels may not seem that important, but they will turn out to be one big nuisance when you might want to view a movie, play video games, or maybe even work in graphic design. Dead pixel detection on time allows you:
Claim Warranties: Most of the manufacturing companies offer a warranty period for the screens. If the dead pixels are found out during the warranty period, then you can replace or get the device repaired.
Prevent Further Damage: The early detection of dead pixels may help in preventing further damage. In some devices, it may prevent additional pixels from malfunctioning if fixed earlier.
Optimize Display Quality: Ensuring that your screen does not have dead pixels maintains the best image quality.

What Should You Do if You’ve Spotted a Dead Pixel?
Finding a dead pixel is never nice and could even be somewhat disheartening for new devices. However, there are a few options you can try before actually replacing the thing.
Pixel Fixing Tools: A number of online tools and apps attempt to “fix” dead or stuck pixels by rapidly cycling colors. Sometimes this can help the pixel start working again.
Screen Massage: Some have been able to recover by gently massaging the screen in a circular motion with the help of a cloth above the dead pixel. Extreme caution should be taken as applying high pressure could cause more damage.
Manufacturer’s Warranty: If the device is still within its warranty period, reaching out to the manufacturer is the best course of action. Some warranties allow for repairs or replacement if the number of dead pixels is up to a certain amount.
Can Dead Pixels Be Avoided?
While it is impossible to prevent dead pixels completely, you can take certain precautions to reduce the likelihood of them occurring:
Avoid Physical Damage: Never press or poke your screen unless absolutely necessary since pressure can damage fragile pixels.
Proper Handling of Devices: Take extra care while handling your gadgets, especially those with a laptop and smartphone, with proper protective casing.
Avoid Long-Time Display Use: Dead pixels can strike any moment when you are using a long-time display. As a matter of fact, turning off the display when not in use will help reduce stress on the pixels.
Regular Testing of Displays: Periodically conduct a dead pixel test to keep your screen healthy and catch problems before they get worse.
Should You Be Concerned About Dead Pixels?
Generally, a single or couple of dead pixels are no big issue. If you happen to notice that there are several of them in one general area, or they’re in the middle of your screen, then you should at least be able to take action in that regard. Working professionally as a graphic designer, video editor, gamer, or some similar occupation, you could find even a few dead pixels annoying.
