What it does
Dead Pixel Test is a free no signup browser tool to check any screen for defects. Cycle through 10 full-screen color tests to spot dead, stuck, or hot pixels on monitors, phones, laptops, and TVs. Includes a stuck-pixel repair mode that flashes rapid colors to revive frozen sub-pixels. 100% browser-side, no install, works on LCD, OLED, and QLED.
Free online dead pixel test. Detect dead, stuck, and hot pixels on any monitor, phone, or TV with 10 fullscreen color screens. No install needed.
Cycle through 10 fullscreen color screens and look for any spot that doesn't match the background — a tiny black dot, a stuck color, or a pixel that stays lit. Works on any monitor, phone, or TV. Hit Start Pixel Test . Your screen goes fullscreen with the black screen first — ideal for spotting hot pixels instantly. Use → arrow key, Space , or swipe left to advance. Each of the 10 screens isolates a different defect type. Note the pixel's position on screen. Stuck pixels sometimes recover after 10–15 minutes on a cycling color test. A dead pixel never lights up. Run the white and color screens — any pixel that stays black is dead. A stuck pixel is permanently red, green, or blue. Cycle…from deadpixeldetect.com

The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
