Screen Bleeding Test – Check Monitor Backlight Bleed Online
Test your screen for backlight bleeding, IPS glow, and clouding with fullscreen black and gray patterns. Free online tool for monitors, laptops, and TVs.
Just tested this on my new LG monitor and it literally saved me from keeping a defective unit. The black pattern immediately revealed uneven backlight bleeding in the bottom-right corner that I hadn't noticed during normal use.
What I really appreciate is the Bleeding vs IPS Glow guide — that flowchart is genuinely helpful. I always wondered if the corner glow on my IPS panel was normal or a defect, and the viewing-angle test made it obvious: my old monitor had IPS glow (shifts when you move your head), while the new one had fixed bleeding (stays in place). That distinction alone is worth the visit.
The brightness control (25/50/75/100%) is a nice touch — being able to compare bleeding at different brightness levels helped me decide the issue was severe enough to warrant a return. The built-in checklist and result guide walk you through a systematic inspection instead of just staring at a black screen and guessing.
Also love that it's 100% browser-based with zero data collection. No app to install, no camera access, no uploads — just CSS background colors on a fullscreen element. You can verify in DevTools that no network requests go out during testing. Privacy-first approach is exactly right for this kind of tool.
Works on everything: my monitor, laptop, even cast to the TV. The 7 test patterns (black, dark gray, gray, white, red, green, blue) cover bleeding, clouding, uniformity, and pixel checks all in one place. Congrats on the launch — this is the kind of utility tool the web was made for. 🔦
