Hi @krish_02_08,

Welcome to HP Support Community.  

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

If you are experiencing vertical lines on the display of your HP laptop, it could be due to various reasons. Here are some steps you can take to troubleshoot and potentially resolve the issue.

• Restart your laptop: Sometimes, a simple restart can resolve display issues. Turn off your laptop, wait for a few seconds, and then turn it back on.
• Update Graphics Drivers: Outdated or corrupted graphics drivers can cause display problems. Visit the official HP website or use the Device Manager to check for and update your graphics drivers.
• Check for Windows Updates: Ensure that your operating system is up-to-date with the latest updates from Microsoft. Sometimes, updates include fixes for display issues.
• External Display Test: Connect your laptop to an external monitor or TV. If the external display works fine without any vertical lines, it may indicate an issue with your laptop's built-in display.
• Adjust Display Settings: Right-click on the desktop, select "Display Settings," and try changing the resolution to see if it affects the appearance of the vertical lines.
• Boot into Safe Mode: Restart your laptop in Safe Mode to see if the problem persists. If the lines disappear in Safe Mode, it may be related to third-party software or drivers.
• Run a Diagnostic Test: Many laptops, including HP, have built-in diagnostic tools. You can run a diagnostic test to check for hardware issues, including problems with the display.
• Check Physical Connections: Ensure that the display cable connecting the screen to the motherboard is securely connected. If the cable is loose or damaged, it could cause display problems.
• Graphics Card Issues: If your laptop has a dedicated graphics card, there may be issues with the card itself. Check the manufacturer's website for any specific troubleshooting steps or driver updates.
• Hardware Failure: If none of the above steps resolve the issue, there may be a hardware problem with the laptop's display or graphics hardware. 

Remember to back up important data before attempting any hardware-related troubleshooting, as some solutions may involve opening up the laptop

I hope this helps. 
 

Take care and have a good day.
