Pattern Generators,


Testing, red, green, blue…


Introducing Patterns, the quintessential video test pattern generator for macOS.  Backed by Metal, Patterns is the world’s first generator to support HDR on the Mac.  It doesn’t stop there, Patterns is also color management compliant allowing for validation through the entire processing path.

Patterns™ for Mac


What you need to know

Patterns™ is best utilized when paired with Portrait Display’s Calman software.  Without Calman, Patterns™ may be used via a web interface allowing manually entry of RGB Triplets for patch generation. With Calman software, Calibration via Calman’s highly accurate Aurora Color Engine is made possible for Internal displays and External Monitors. 

For Calman, A valid Calman license and version 5.13.1 or higher required.

Color accuracy starts here and goes… there.

Accuracy is important, very important.  Whether creating or consuming content having an accurate image ensure’s the artist’s intent is as intended.  Photography, Visual Effects, Editing, Color Grading, Web Surfing, ect. Color makes a difference.

Patterns™ is designed to test the system, not just the display.  The app is designed to work in the color spaces you work in.  While other solutions may test a single path, Patterns™ is designed to test many; after all, your web browser may be in sRGB but that movie you’re color grading could be in P3-D65, ST 2084, so why would you only calibrate or test sRGB?  

Question? Nothing.

Creatives demand accuracy, just one question can delay a project minutes, hours, even days while engineers scramble to find solutions to problems that all come down to confidence in the display creative decisions are decided upon.  

Aurora Color Engine Capacity

The immense power of the Aurora Color Engine can now be used to calibrate displays on Mac OS systems.

Portrait Displays’ Aurora Color Engine will characterize and calibrate a device as it behaves within the Mac OS color management environment. An ICC profile is generated that includes accurate colorimetry of the measured display and a grayscale calibration. By creating an ICC profile, not only will your device be color accurate to a single-color space, but it will also be color accurate in all of your working color spaces.

The perfect Pro Display XDR companion.

You validate me.  Patterns™ paired with Calman is the perfect companion for Pro Display XDR allowing for calibration and validation.  If color accuracy was a crime, you could lock these two up.  We all want that perfect partner in life and Pro Display XDR is no exception.
