Other causes of horizontal lines on the HP laptop screen may include software or driver issues or even a virus or malware infection.

• Malfunctioning LCD Panel: A defective or damaged LCD screen can result in visible lines. The LCD panel is crucial for displaying images, and any fault may cause these issues.
• Faulty Video Card: A damaged or defective video card can also lead to horizontal or vertical lines. If this is the issue, the video card may need replacement.

Solution:

• Update or reinstall the laptop’s graphics drivers.
• Perform a system update to ensure all software is up-to-date.

3. Virus or Malware Infection

A virus or malware infection can interfere with the system’s performance, including the display, leading to lines on the screen.

Solution:

• Run a full virus scan using reliable antivirus software.
• Remove any detected threats and restart the laptop.

4. Overheating

Prolonged overheating can damage internal components like the GPU, causing display distortions.

Solution:

Solution:

• Contact HP support if your laptop is under warranty for possible replacements or repairs.

Method 1: Reconnect the Video Cable

If the laptop has a removable video cable, disconnect and reconnect it firmly to the port on the back of the computer. If the cable is damaged, replace it.

But if you are using an external monitor, try connecting the monitor to a different port on the back of the computer. If the problem persists, try a different monitor.
