Screen Issues

Screen Issues is a free online screen test tool for anyone who wants to check a monitor, laptop display, phone screen, tablet, or external panel without downloading software. It helps you quickly diagnose dead pixels, stuck pixels, bright spots, dark spots, horizontal or vertical lines, uneven colors, gradients, banding, backlight issues, and flickering. Open the website in a modern browser and choose the test mode that matches what you want to inspect. Solid color screens make individual pixel defects easier to see, while contrast and gradient tests help reveal subtle display problems. The service is designed as a simple browser-based screen testing utility, with clear instructions and multiple test modes for home users, buyers checking a used monitor, technicians, designers, gamers, and anyone troubleshooting a display. Screen Issues does not require an account, installation, or download. For best results, clean the panel first, view the display in a comfortable room, and inspect it from normal viewing distance as well as close up. The guides explain what different visual symptoms can mean and how to document a problem. Results are informational and should be confirmed against manufacturer warranty policies or professional diagnostics when needed. Screen Issues is free to use and focuses on practical, accessible display testing for everyday devices.
