What it does
Free online tools to test pixels, check screen uniformity, inspect touch zones, and identify display problems—no downloads or account required.
Free browser-based tools to test pixels, inspect display uniformity, check touch zones, and repair stuck pixels.
A focused toolkit for finding pixel defects, checking panel uniformity, and testing touch input — without downloads or guesswork. Start with the tool that matches your symptom. Every test is designed to be understandable at a glance. Find dead, stuck, or uneven pixels with fullscreen color fields, subpixel grids, and contrast patterns. Position a compact color exciter over the problem area and work at a controlled refresh rate. Paint across a responsive grid to reveal exactly where a phone or tablet stops registering touch. Use calibrated gray fields to inspect OLED burn-in, IPS glow, backlight bleed, and dirty-screen effect. A stuck pixel can often be stimulated back to life. A dead pixel…from pixeltestonline.com

Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
