Hi @Nikhil141727,

Welcome to The HP Support Community.

Vertical lines on a display can indicate hardware or software issues. Here's a step-by-step guide to troubleshoot and hopefully resolve the issue:

Step 1: Check for External Damage

• Inspect the Screen: Look for any visible damage on the screen.
• Check Cables: Ensure all cables (if using an external monitor) are securely connected.

Step 2: Restart Your Computer

• Simple Restart: Sometimes, restarting your computer can resolve display issues.

Step 3: Update Graphics Drivers

1. Open Device Manager:
   • Press Win + X and select Device Manager.
2. Update Driver:
   • Expand Display adapters.
   • Right-click your graphics card and select Update driver.
   • Choose Search automatically for updated driver software.

1. Open Settings:
   • Press Win + I to open the Settings app.
2. Update & Security:
   • Go to Update & Security and click on Check for updates.

Step 5: Test with External Monitor

• Connect External Monitor: If the vertical line doesn't appear on the external monitor, the issue might be with your display.

Step 6: Boot into Safe Mode

1. Enter Safe Mode:
   • Press Win + R, type msconfig, and press Enter.
   • Go to the Boot tab and check Safe boot, then restart your PC.
2. Check Display: If the line disappears, it could be a driver or software issue.
