What is EDID Parser?
The EDID Parser is a technical tool designed to interpret the Extended Display Identification Data sent by monitors and displays. By integrating this capability into Openclaw Skills, developers and system administrators can programmatically access detailed hardware specifications such as manufacturer details, supported resolutions, and refresh rates. This skill bridges the gap between raw binary hardware data and actionable insights, making it an essential asset for anyone working with display subsystems or debugging hardware connectivity.
Whether you are interacting with the Linux DRM/KMS subsystem or analyzing standalone binary files, this tool simplifies the complexity of display metadata. By using Openclaw Skills to handle these low-level tasks, users can automate hardware inventories and perform deep-dive diagnostics without needing to manually decode hex values.
EDID Parser Use Cases
- Debugging HDMI, DisplayPort, or CEC connection and handshaking issues.
- Auditing display capabilities across multiple workstations or server nodes.
- Validating EDID binary files for firmware development and hardware testing.
- Generating human-readable reports from raw sysfs display data on Linux.
- Extracting display metadata into JSON format for automated asset management.
How EDID Parser Works
- The skill identifies display outputs via the Linux sysfs interface or accepts path inputs to binary EDID files.
- It reads the raw data to verify the existence of a valid 128-byte or 256-byte EDID structure.
- The system performs a header and checksum validation to ensure data integrity.
- Using underlying scripts and edid-decode, the tool parses the data into structured categories like timing, color space, and manufacturer info.
- The results are formatted into diagnostic reports or JSON objects for the user or calling agent.
EDID Parser Setup
To use this within the Openclaw Skills environment, ensure the system dependency is installed:
sudo apt-get update
sudo apt-get install edid-decode
Verify your display outputs are accessible:
bash scripts/list_outputs.sh
EDID Parser Data Schema & Taxonomy
| Data Point | Description | Output Format |
|---|---|---|
| Identity | Manufacturer code, model name, and serial number. | String |
| Timings | Supported resolutions and refresh rates (e.g., 1080p @ 60Hz). | List |
| Color Space | Support for RGB, YCbCr, and HDR metadata. | JSON |
| Validation | Checksum status and header integrity results. | Boolean |
| Physical | Screen size in centimeters and production dates. | Integer/Date |
EDID Parser Advanced Features
- Batch processing capabilities to validate and summarize entire directories of EDID samples simultaneously.
- Diagnostic report generation that automatically flags missing Detailed Timing Descriptors (DTD) or invalid headers.
- JSON extraction mode for high-speed integration with external monitoring databases or inventory scripts.
- Cross-platform support for raw hex data strings, allowing analysis of logs from non-Linux systems.
- Built-in test samples for 4K TVs and 1080p monitors to facilitate quick testing of Openclaw Skills workflows.
