Vertical lines appearing on your display can be frustrating. Here are the most common causes:

Hardware Issues

Damaged display panel — Physical damage from drops or pressure often creates permanent vertical lines. The liquid crystal layer inside the screen may be cracked or compromised.

Loose or faulty cable connection — The ribbon cable connecting your display to the motherboard can become loose or damaged, interrupting the signal and causing lines to appear.

Graphics card problems — A failing GPU or its connection to the display can produce artifacts including vertical lines, especially if they flicker or change with different applications.

Software Issues

Outdated or corrupted display drivers — Driver conflicts or outdated graphics drivers can sometimes manifest as visual glitches including vertical lines.

Operating system glitches — Temporary software bugs may cause display issues that can often be resolved with a restart.

Quick Troubleshooting Steps

  1. Restart your device to rule out temporary software glitches
  2. Update your graphics drivers to the latest version
  3. Connect an external monitor (for laptops) to determine if the issue is with the display or graphics card
  4. Gently press around the screen bezels to check for loose connections

When to Seek Professional Help

If lines persist after basic troubleshooting, you likely have a hardware issue requiring professional repair. Screen replacements are common fixes for this problem.

Prevention tip: Use a protective case and avoid applying pressure to your screen to minimize the risk of display damage.
