Troubleshooting: Black Lines on Screen
Seeing a black line on computer screen can be frustrating. It could be a software glitch or a hardware failure. Here is how to fix it:
Step 1: Check the Cable
If you are using a desktop, ensure the VGA/HDMI cable is plugged in tightly. If the cable is damaged, replace it.
Step 2: Update Graphics Drivers
Go to your Device Manager and update your Display Adapters. Sometimes outdated drivers cause display artifacts. Learn more on MSDN Documentation.
Step 3: Check for Physical Damage
If the line is persistent even during the BIOS startup, it might be a cracked LCD panel. In this case, the screen may need replacement.
Our hardware assembly and maintenance workshops cover these troubleshooting steps in detail.
