Screen Issues is a free online resource for identifying, understanding, and troubleshooting display defects on monitors, laptops, phones, and tablets. It helps you check a display before you decide whether a panel is fine, a pixel is stuck, or a closer look is needed.
What it does
The interactive Screen Test tool runs full-screen solid colors in the browser. Those colors are white, black, red, green, blue, and gray. Nothing is installed: the test runs with no download. In seconds you can spot dead pixels, stuck pixels, bright spots, black spots, backlight bleed, and color uniformity issues. The same tool is built to instantly diagnose dead pixels, lines, color issues, and flickering. Multiple test modes are included.
Who it is for
Screen Issues is for people checking monitors, laptops, phones, and tablets. Expert guides sit alongside the tool and cover dead pixels, screen lines, flickering, pressure marks, color and tint problems, and device-specific cases for Mac, laptop, and mobile. The content is available in English, German, Spanish, and Portuguese.
Pricing and access
Pricing is free. You use the Screen Test online at the Screen Issues website. No download is required. Open a solid color, view it full screen, and compare what you see with the troubleshooting guides.
