Your laptop screen is one of the most important components—whether you’re working, gaming, or watching videos, a faulty display can ruin the experience. If you’re noticing dead pixels, flickering, color distortion, or uneven brightness, this guide will help you test and troubleshoot your laptop’s screen.

Why Laptop Display Testing is Important

A damaged or misconfigured display can cause:

• Blurred or distorted visuals that affect productivity.
• Eye strain due to improper brightness or color settings.
• Hidden defects like dead pixels that worsen over time.

Testing your laptop display regularly helps catch issues early and ensure a smooth experience.
