Troubleshooting White Spots on a Laptop Screen: Causes and Solutions


What could cause irregular white markings on a laptop screen that are not visible when the device is off?

I have an Acer Nitro 5 laptop that has developed some strange white markings on the screen, as shown in this photo. The markings are not physical, as there is no difference in texture when I touch them. They are only visible when the laptop is on, and they appeared suddenly overnight. They do not look like typical dead pixels or hardware failures, as they are very uneven and scattered. I have tried restarting the laptop, but that did not help. I have also searched online and found some similar cases, where the cause was attributed to the screen being pressed by the keyboard when the laptop was closed. However, I do not think that is the case for me, as I am very careful with my laptop and do not put anything on top of it when it is closed. I am worried that this is a serious hardware issue that might require a screen replacement, but I am hoping to find a more accurate diagnosis and a possible solution. Any expert advice would be greatly appreciated. Thank you.


If you have noticed some white spots or marks on your laptop screen, you might be wondering what caused them and how to fix them. White spots on a laptop screen can be annoying and distracting, especially if they are large or numerous. They can also indicate a serious problem with your laptop’s display or hardware.

There are several possible causes of white spots on a laptop screen, and they can be classified into two categories: software and hardware. Software issues are easier to fix, as they usually involve updating or reinstalling the drivers or programs that control the display. Hardware issues are more complicated, as they may require opening the laptop and replacing or repairing the damaged components.

To determine whether the white spots on your laptop screen are caused by software or hardware, you can try the following steps:

  • Connect your laptop to an external monitor or TV using an HDMI or VGA cable. If the white spots do not appear on the external display, it means that the problem is with your laptop’s screen or graphics card. If the white spots appear on both displays, it means that the problem is with your laptop’s software or operating system.
  • Restart your laptop in safe mode or BIOS mode. Safe mode is a diagnostic mode that only loads the essential drivers and programs, while BIOS mode is a pre-boot mode that allows you to access the basic settings of your laptop. If the white spots do not appear in safe mode or BIOS mode, it means that the problem is caused by a software conflict or corruption. If the white spots appear in both modes, it means that the problem is caused by a hardware defect or damage.
  • Depending on the results of these tests, you can try the following solutions to fix the white spots on your laptop screen:

  • If the problem is caused by software, you can try updating or reinstalling the display drivers, the graphics card drivers, or the operating system. You can also scan your laptop for viruses or malware that might affect the display. You can also try restoring your laptop to a previous point when the white spots did not appear, or resetting your laptop to its factory settings. However, before doing any of these steps, make sure to back up your important files and data, as they might be deleted or overwritten.
  • If the problem is caused by hardware, you can try cleaning the laptop screen with a soft cloth and a mild solution of water and vinegar. Sometimes, dust or dirt can cause white spots on the screen. You can also try applying gentle pressure on the screen or tapping it lightly with your finger or a pen. Sometimes, this can fix stuck pixels or loose connections. However, be careful not to damage the screen further. If these methods do not work, you might need to open the laptop and check the screen, the graphics card, or the motherboard for any signs of damage or malfunction. You might need to replace the screen or the graphics card, or repair the motherboard. However, unless you are experienced and confident in doing this, it is better to seek professional help from a qualified technician or a laptop repair service.
