Adjust Monitor Refresh Rate

If the white dots persist, it may be worth adjusting the refresh rate settings on your device. The refresh rate refers to the number of times per second that the image on your screen is refreshed. Sometimes, a mismatch between the refresh rate of your monitor and the output from your device can cause screen flickering, including the appearance of white dots.

To adjust the refresh rate, follow these steps based on your operating system:

  1. Windows:

1. Right-click on your desktop and select “Display settings” from the context menu.

2. Scroll down to the “Advanced display settings” section and click on it.

3. In the new window, click on the “Display adapter properties” link.

4. Navigate to the “Monitor” tab.

5. Under the “Monitor Settings” section, you will find the available refresh rate options. Select a different refresh rate from the drop-down menu and click “Apply” to test it.

  1. macOS:

1. Click on the Apple menu and select “System Preferences.”

2. In the System Preferences window, click on “Displays.”

3. Switch to the “Display” tab.

4. Hold down the “Option” key on your keyboard and click on the “Scaled” button.

5. A list of available refresh rate options will appear. Select a different refresh rate and check if the issue is resolved.

If adjusting the refresh rate does not eliminate the white dots on your screen, continue troubleshooting using the next section of this guide. Remember, each step is designed to help you identify and resolve the issue, so proceed systematically until a solution is found.

This step is pivotal in narrowing down the source of the screen flickering problem and finding an appropriate solution.

Check the Video Card

If you’re using a desktop computer, it’s important to inspect your video card for any issues. The video card is responsible for rendering images and videos on your screen, and a faulty card can cause screen flickering or the appearance of white dots. Here are some steps to help you check your video card:

  1. Power off your computer and unplug it from the electrical outlet for safety.
  2. Open your computer case to access the internal components. Refer to your computer’s manual or manufacturer’s website for specific instructions.
  3. Locate the video card, which is usually inserted into a PCI Express slot on the motherboard. Ensure that the card is securely seated in the slot.
  4. Check the video card for any physical damage or loose connections. Gently remove the card and reinsert it if necessary.
  5. If you have an extra video card or can borrow one from a friend, consider testing with a different card to see if the issue persists. This can help determine if the problem lies with the video card itself.

Remember to handle the video card with care and avoid touching the sensitive components. Once you have inspected and tested the video card, you can close your computer case and power it back on to see if the white dots flashing issue has been resolved.
