Display getting coloured dots

Hi @Swamy512,

Welcome to HP Support Community.

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

If you're seeing colored dots on your HP Notebook - 15 display, it could be due to several issues. Here’s a checklist to help you diagnose and possibly fix the problem.

Check for External Damage: Inspect the screen for any visible cracks or damage. Physical damage could cause display issues.

Restart Your Laptop: Sometimes a simple restart can resolve display issues caused by temporary glitches.

Update Graphics Drivers:

• Go to Device Manager (right-click on the Start button and select it).
• Expand the Display adapters section.
• Right-click on your graphics card and select Update driver.

Check for Loose Connections:

• If you're comfortable, you can check the internal connections by opening the back panel of your laptop. Ensure the display cable is securely connected to the motherboard.

Run a Display Test:

• Some HP laptops have built-in diagnostics. You can access this by pressing Esc repeatedly while the laptop is starting up and then selecting F2 for Diagnostics. Check the display test to see if it reports any issues.

External Monitor Test:

• Connect your laptop to an external monitor or TV. If the colored dots appear only on the laptop screen and not on the external display, it’s likely a problem with the laptop screen itself or its connections.

Adjust Resolution and Refresh Rate:

• Right-click on the desktop and select Display settings.
• Check if changing the resolution or refresh rate helps. Sometimes incorrect settings can cause display artifacts.

Perform a Hard Reset:

• Turn off your laptop.
• Disconnect all external devices and the power adapter.
• Press and hold the power button for about 15 seconds.
• Reconnect the power adapter and restart your laptop.

Check for Software Issues:

• Boot into Safe Mode to see if the problem persists. If it doesn’t, it could be related to a software or driver conflict.

I hope this helps.

Take care and have a good day.
