Hi @PRADIP3406 

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

If you're seeing white dots on your HP laptop display, this could be due to several possible causes, such as a hardware issue, software problem, or even something related to the display settings. Here's how you can troubleshoot and potentially fix the issue:

1. Check for Physical Damage

• Inspect the screen: Ensure there are no cracks or physical damage to the display. Physical damage can sometimes cause random white or colored dots on the screen.
• Clean the screen: Sometimes dirt or smudges can create the illusion of dots. Gently wipe the screen with a soft, microfiber cloth.

2. Restart Your Laptop

• Reboot: A simple restart can sometimes resolve temporary software glitches that might be causing the white dots.
• Press Ctrl + Alt + Delete and select Restart, or turn off the laptop and then turn it back on.

3. Check for Software or Display Driver Issues

• Update Graphics Drivers: Outdated or corrupted graphics drivers can cause display issues, including white dots.
  • Go to Device Manager (you can search for it in the Start menu).
  • Expand the Display adapters section.
  • Right-click on your graphics card and select Update driver.
  • Follow the on-screen instructions to check for and install updates.
• Roll Back Drivers: If the white dots appeared after updating the display drivers, rolling them back to a previous version may help:
  • In Device Manager, right-click on your graphics card, select Properties, go to the Driver tab, and choose Roll Back Driver if available.

4. Check Display Settings

• Resolution and Refresh Rate: Ensure your screen resolution and refresh rate settings are correct.
  • Right-click on the desktop and select Display settings.
  • Scroll down to Advanced display settings and verify the resolution and refresh rate are set to the recommended values for your display.

5. Test with an External Monitor

• Connect your laptop to an external monitor or TV using the appropriate cable (HDMI, VGA, etc.).
• If the white dots are only visible on the laptop screen and not on the external monitor, it's likely a hardware issue with the laptop's display.
• If the white dots appear on both screens, this could indicate a problem with the graphics card or driver.

6. Perform a Hardware Diagnostic

• Many HP laptops have built-in diagnostics that can help identify hardware issues.
  • Turn off your laptop.
  • Press the Esc key and immediately start tapping the F2 key to enter the HP Hardware Diagnostics menu.
  • Run a Display Test to see if any hardware issues are detected with the screen.

I hope this helps.

Take care and have a good day.
