PGenerator-Plus

Project Overview

PGenerator+ is a free, open-source Raspberry Pi-based display calibration suite built around a precision HDMI test pattern generator, aimed at home users and display enthusiasts who want to produce accurate SDR, HDR10, HLG, and Dolby Vision test patterns.

Key Features

• Precision HDMI pattern generation: Full-screen patches, grayscale ramps, color bars, custom RGB triplets, and more
• HDR and Dolby Vision output: HDR10 (ST.2084 PQ), HLG, and Dolby Vision Low-Latency
• Network-controlled: Supports Calman, ColourSpace/LightSpace, HCFR, and other calibration software
• Local web dashboard: HDMI signal settings, manual pattern injection, real-time infoframe decoding, and more
• LG autocal: SDR and HDR greyscale, RGB balance, and 3D LUT profiling
• Meter-driven validation: Integrated ArgyllCMS spotread workflow
• Display profile creation: Windows MHC2 and KDE HDR cLUT profiles

Target Audience

• Home theater and display calibration enthusiasts
• Professional display calibration technicians
• Raspberry Pi developers

Quick Start

1. Install PGenerator+ on a Raspberry Pi
2. Connect your display via HDMI
3. Access the local web dashboard for control
4. Select a calibration mode (SDR/HDR/Dolby Vision)
5. Use a USB colorimeter or spectrophotometer for closed-loop calibration
