Hi Product Hunt! I built White Screen Tester as a simple, free browser-based tool for checking display issues without installing anything. You can use it to test dead pixels, stuck pixels, screen dust, brightness problems, color uniformity, and backlight bleed on phones, laptops, tablets, monitors, and TVs. The goal was to make it fast and simple: open the site, choose a screen color, go fullscreen, and inspect your display. I’d love your feedback on the tool, especially the fullscreen experience, color options, and any extra display testing features you think I should add.
