What Are The Common Causes Of HP Laptop Horizontal or Vertical Lines On Screen?
Horizontal or vertical lines on the display of an HP laptop are a common problem that can occur for various reasons.

Other causes of horizontal lines on the HP laptop screen may include software or driver issues or even a virus or malware infection.
Hardware Issues
The screen may display horizontal or vertical lines if the laptop has a faulty video card. It can occur when the video card is damaged or has a defect. In this case, the video card may need to be replaced.
A malfunctioning LCD panel is another possible cause of lines on the HP laptop screen. The LCD panel is responsible for displaying the images on the screen, and if the panel is damaged or defective, it may cause the laptop to display lines.
A cracked display is another common cause of horizontal or vertical lines on the laptop. When the display is cracked, the lines may appear due to the damage. In this case, the display will need to be replaced.
Software or Driver Issues
In some cases, the horizontal or vertical lines on the HP laptop screen may be caused by software or driver issues. If the laptop has outdated drivers or the software is corrupted, this may cause the laptop to display lines. The drivers and software will need to be updated or reinstalled.
Virus or Malware Infection
A virus or malware infection can also cause horizontal or vertical lines on the HP laptop screen. If the laptop is infected with a virus or malware, it can cause the laptop to display these lines. The laptop must be scanned for any viruses or malware and then cleaned.
