PiXel Check

PiXel Check is a macOS‑only utility that scans a connected display for dead or stuck pixels. It presents a series of full‑screen colour patterns, allowing the user to observe any pixel that fails to change colour correctly. The tool records the locations of problematic pixels and can highlight them for easy identification.

The software is aimed at users who need to verify the integrity of their monitors, such as photographers, graphic designers, or anyone concerned about screen quality. By providing a straightforward visual test, it helps determine whether a display meets the required standards before purchase or after extended use.

PiXel Check is released as a stable version, offering a simple, no‑frills interface without additional configuration options. It is distributed directly from its homepage for macOS systems.
