TestCard
TestCard is a macOS utility for testing and displaying video test patterns and color cards on your display. It is commonly used by video professionals, broadcast engineers, and content creators to calibrate monitors, verify color accuracy, check for dead pixels, and validate video output during production and post-production workflows. The app generates standard test cards such as color bars, grayscale gradients, focus patterns and alignment grids that can be displayed full-screen or windowed.

1 suggestionWe could not confirm whether a native Apple Silicon build of TestCard exists — the web search results did not return information about the app itself, making it difficult to assess the developer's current activity or plans. We recommend contacting the developer directly at the bundle ID domain (sigma6.ch) to ask whether a native Apple Silicon version has been released or is planned. If the developer is no longer maintaining the app, you might consider alternatives such as FiveActs TestCard, Resolution Changer, or using QuickTime Player's built-in test patterns and professional display calibration tools like Calman or X-Rite i1Profiler, which offer native Apple Silicon support.
