@Surya_teja_1803, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

If you are encountering two blue lines on the screen of your HP Pavilion x360 14 inch 2-in-1 Laptop PC 14-ek1000 (742H9AV), it may indicate an issue with the display or the graphics driver. Here are some steps you can take to diagnose and possibly resolve the issue:

Restart Your Computer: Sometimes, a simple restart can resolve display issues if they are temporary glitches.

Update Graphics Drivers:

• Ensure that your graphics drivers are up to date. You can do this through the Device Manager in Windows by right-clicking on the graphics card and selecting "Update driver".
• You may also visit the HP Support website to download the latest drivers for your specific model.

Check Display Settings:

• Go to Display Settings by right-clicking the desktop and selecting "Display settings". Ensure the correct resolution and refresh rate are set for your display.

External Display Test:

• Connect your laptop to an external monitor. If the lines do not appear on the external display, the issue is likely with the laptop's screen.
• If the lines appear on both screens, it may be a graphics card issue or software problem.

Perform a Hardware Diagnostic:

• Use the built-in HP Hardware Diagnostics tool to check for hardware issues. This can often identify whether there's a problem with the display or other hardware components.
