What Are the Causes of black line on laptop screen hp?
Identifying the cause of the problem is always the first step towards troubleshooting. In this case, these are the most viable answers to why lines could be appearing on the screen:
Broken display cable—An internal connection between the display and motherboard that is improperly connected or damaged.
Outdated graphics driver—Drivers that are not up-to-date or corrupted may result in display issues.
Screen damage—Impact trauma can create black patches or vertical lines.
Overheating—Excessive temperatures can affect the display, especially if it’s close to the graphics chip.
Dead pixels—Black dots or lines appearing on a screen can also be the result of inactive or unresponsive pixels.
LCD panel problems arise from manufacturing defects or aging components within the display.
Step-by-Step Guide to Remove the Black Line From an HP Laptop Screen
Remove black lines from your screen using these strategies:
Restart Your Laptop
Bugs and display issues may be resolved by restarting your device.
Update or Reinstall Graphics Drivers
To do this, go to Device Manager > Display Adapters > right-click on your GPU and either update or uninstall and reinstall the driver.
Check the Display Cable
Connect your HP laptop to an external monitor. A blank external display means the problem is your laptop screen or display cables. Opening the case and reconnecting or replacing the cable requires expertise.
Run a Hard Reset on HP Laptop
Power off, unplug the charger, and remove the battery (if removable). Press the power button for 15 seconds, reconnect everything, and restart.
Boot In Safe Mode
If safe mode eliminates the black lines, the problem is likely driver or software-related.
Look for Damage to the Equipment
Inspect the device using a flashlight for any cracks and dark marks. If you observe any signs of damage, a screen replacement is likely necessary.
Restore the Device to Factory Settings
Go to Settings > Recovery > Reset this PC.
Make a selection between keeping files or removing everything.
This option should only be utilized when all else has failed.
