How to check for dead pixels on monitor?

Are you concerned that your new monitor has dead pixels? Dead pixels can be frustrating, as they can impact your viewing experience. In this article, we will guide you on how to check for dead pixels on your monitor, along with some related frequently asked questions.

What are Dead Pixels?

Dead pixels are tiny spots on your monitor’s screen that do not display any color. They appear as small black or white dots that stand out from the rest of the screen. These pixels are essentially malfunctioning and can occur due to manufacturing defects or physical damage.

How to Check for Dead Pixels on a Monitor?

The best way to check for dead pixels on your monitor is by using a dead pixel test. Here’s how you can do it:

1. Open your preferred internet browser and search for a dead pixel test or go directly to a dead pixel test website.
2. Choose a test that suits your needs. The most common test displays solid colors, one color at a time.
3. Set your monitor’s display to full-screen mode.
4. Carefully examine the entire screen for any abnormal black or white spots.
5. Switch between different colors. Dead pixels are easier to spot on solid backgrounds.
6. Repeat the process with different solid colors until you have checked the entire screen.

Remember, it is crucial to perform this test on a newly purchased monitor while it is still under warranty. If you discover any dead pixels, contact the manufacturer or the retailer for support.

Frequently Asked Questions

1. Can dead pixels be fixed?

No, dead pixels cannot be fixed. Once a pixel is dead, it cannot be revived. However, you may be eligible for a replacement if your monitor is still under warranty.

2. How many dead pixels are acceptable?

Acceptable dead pixel policies vary by manufacturer. Some companies consider a small number of dead pixels to be within normal limits, while others have a zero-tolerance policy. Check your monitor’s warranty or contact the manufacturer for specific information.

3. Do all monitors have dead pixels?

No, not all monitors have dead pixels. However, it is not uncommon for new monitors to have a few dead pixels due to manufacturing processes.

4. Can dead pixels increase over time?

Dead pixels typically do not increase over time. Once they are present, they usually remain the same. However, it is possible for more dead pixels to appear if your monitor sustains physical damage.

5. Can a dead pixel spread?

No, dead pixels cannot spread to other areas of the screen. Each dead pixel is a localized issue and does not affect neighboring pixels.

6. How do dead pixels occur?

Dead pixels can occur during the manufacturing process when a pixel is stuck or damaged. They can also develop due to physical damage, such as pressure applied to the screen.

7. How to prevent dead pixels?

Unfortunately, dead pixels cannot be prevented. However, handling your monitor with care and avoiding any physical damage can help minimize the risk of dead pixels.

8. Are dead pixels covered by warranty?

Most monitor manufacturers offer dead pixel warranties. However, the coverage and policies may vary. Make sure to check your warranty terms to determine if dead pixels are covered for replacement.

9. Can dead pixels affect the screen’s performance?

Dead pixels do not typically impact the overall performance of the screen. However, they can be visually distracting, especially when viewing images or videos.

10. Can dead pixels be seen on all backgrounds?

Dead pixels are more noticeable on solid backgrounds. They may be less visible when the screen displays complex images or videos with changing colors.

11. Are there any software solutions to fix dead pixels?

While there are some software programs claiming to fix dead pixels, their effectiveness is uncertain. It is best to rely on the manufacturer’s warranty or get professional assistance if your monitor has dead pixels.

12. Can dead pixels cause image burn-in?

No, dead pixels cannot cause image burn-in. Image burn-in occurs when specific pixels are frequently displaying static images for extended periods. Dead pixels, by definition, do not display any images.


Checking your monitor for dead pixels is essential, especially when it is under warranty. The dead pixel test allows you to identify and report any defective pixels to the manufacturer for potential replacement. Remember, dead pixels cannot be fixed, so early detection is key.
