In today’s high-definition world, ensuring your display is properly calibrated isn’t just a luxury—it’s a necessity. Whether you're a home cinema enthusiast, a professional installer, or someone who demands the most accurate colours and tones from your screen, the right tools make all the difference. Enter the Portrait Displays G1 — a compact yet powerful pattern generator designed to streamline calibration and enhance visual fidelity.
Why Calibration Matters
For those who care about image purity, factors like colour accuracy, grayscale linearity and HDR performance are critical. Mis-calibrated displays can suffer from washed-out blacks, inaccurate skin tones or improper HDR tone mapping. Having a tool that can provide reference-level test patterns is a major leap forward.
Meet the G1
The G1 stands out thanks to its portability and compatibility. Measuring just about 95 mm long and powered via USB-C, it integrates seamlessly into a rack or home setup. Its HDMI 2.0 output supports resolutions up to 4096×2160 at 60Hz, and it handles SDR, HDR10, HLG and Dolby Vision formats — a full spectrum of modern display workflows.
Key Features at a Glance
4K Output & HDR Support: The G1 outputs full 4K resolution and supports major HDR formats, ensuring your testing environment matches the latest display technologies.
Automated via Calman: When paired with the Calman software, everything from patch generation to automation becomes streamlined. That means less manual setup and more time focused on fine-tuning.
Comprehensive Test Patterns: Whether you’re checking brightness, contrast, colour bars, grayscale ramps or checkerboards, the G1 delivers a wide array of built-in patterns.
Portable, Plug-and-Play Ready: With its compact form factor and USB-C power, the unit is easy to transport and deploy in multiple environments.
Entry-Level Friendly: While it offers professional-grade capability, the G1 is positioned as an entry point into calibration excellence — making it accessible for enthusiasts and semi-professionals alike.
Who Should Consider the G1?
Home cinema enthusiasts wanting to calibrate their 4K TVs or projectors with better accuracy.
AV installers who need a portable, reliable pattern generator on-site.
Content creators or post-production studios seeking to validate HDR workflows without investing in bulky hardware.
Anyone curious about display calibration and wanting a streamlined, software-driven solution.
Things to Note
The G1 works only with the Calman software (version 5.15.0.4 and later). Be sure your workflow supports this.
While “entry-level,” the output and features are very capable — expect professional results, but also ensure your display chain (TV/projector, cables, environment) is up to the task.
For full benefit, you’ll need a calibrated meter and a controlled environment (dark or dim lighting, neutral surroundings) to maximise the accuracy.
Conclusion
If you’re looking to take your display accuracy to the next level without diving into massive hardware investments, the Portrait Displays G1 is a compelling choice. Compact, capable and geared for HDR-ready workflows, it brings professional-grade test patterns and automation into the reach of enthusiasts and pros alike. Whether you’re building a home theatre, calibrating client displays or preparing content with confidence, this little device might just be the missing piece in your workflow.
