About Screen Issues

Learn about Screen Issues — our mission to help everyone identify and understand screen defects, from dead pixels to backlight bleed, with free tools and expert guides.

About Screen Issues

Screen Issues is a free online resource dedicated to helping people identify, understand, and address defects on LCD and OLED displays. Whether you just discovered an odd bright spot on your monitor, spotted a thin colored line across your laptop screen, or are trying to figure out if you have a dead pixel, we are here to guide you through it.

Who We Are

We are a small team of display enthusiasts and technical writers who have spent years studying how LCD and OLED screens work — and what happens when they do not. Our platform combines an interactive free screen test tool with a growing library of expert-written guides that break down complex display problems into clear, actionable information.

We built Screen Issues because screen defects are more common than people realize, and getting reliable information should not require digging through forum threads or paying for a diagnosis. Every guide we publish is researched thoroughly, reviewed for accuracy, and updated whenever display technology evolves.

Our Mission

Our mission is simple: make screen diagnostics accessible to everyone.

We believe that anyone should be able to identify a screen defect on their own — without needing a technical background, a repair manual, or a trip to a service center. By providing the right tools and the right information, we help users understand exactly what is wrong with their display so they can make informed decisions about what to do next.

What We Offer

Free Online Screen Test Tool

Our browser-based screen test tool lets you run your display through a series of full-screen test patterns — solid colors, primary colors, grayscale gradients, and more — to identify issues that are hard to spot in normal use. No download, no installation. Just open the tool and run the test.

Expert Diagnostic Guides

We publish detailed articles covering the full spectrum of screen defects:

  • Dead pixels and stuck pixels — permanent vs. temporary failures
  • Bright spots and backlight bleed — pressure damage vs. internal leakage
  • Lines on screen — vertical, horizontal, colored, and flickering
  • Color problems — tint issues, color casts, and uneven lighting
  • Spots and stains — pressure marks, liquid damage, and manufacturing defects

Every guide covers what the problem looks like, what causes it, how to confirm it, and what your options are — from software fixes to professional repair.
