Key Features

8K & 4K Resolution Support: Maintains reliable DisplayPort 1.4 communication up to 8K@30Hz and 4K@60Hz with 32.4Gbps bandwidth (HBR3). Fully compliant with HDCP 2.3/2.2/1.x standards, ensuring reliable interoperability across modern displays and sources.

 

Advanced EDID Management: Includes five factory-loaded Gefen EDID profiles optimized for common display configurations, plus three user-programmable memory banks. Quickly adapt to unique system setups or troubleshooting scenarios without reprogramming every time you switch displays.​

 

Active Signal Integrity: Auxiliary channel re-clocking and active HPD (Hot Plug Detect)/Link Training maintain proper handshaking even when the display is disconnected, eliminating intermittent signal loss, flicker, or blank screens during system reconfiguration.​

 

Premium Format Preservation: Supports HDR10, HDR10+, Dolby Vision, and HLG video formats while preserving immersive audio including Dolby Atmos® and DTS:X™. Ensures your high-end content maintains full fidelity through complex routing and switching scenarios.​

 

USB-C Programmability: Easy EDID programming, firmware updates, and field service access via USB-C port. The USB-C connection enables flexible EDID management and keeps the unit adaptable to evolving AV systems.

 

Secure Configuration Protection: Two-position write-enable switch protects stored EDIDs from accidental overwriting during operation. Once configured for critical installations, lock settings to ensure reliable, repeatable performance in critical workflows.

 

Field-Ready Design: Compact metal enclosure (90mm × 72mm × 20mm) with surface-mount capability fits seamlessly into rack installations or field deployments. Bi-color LED indicators provide instant visual confirmation of power, HPD status, and active EDID bank selection.

How It Works

Setup (Plug-and-Play)
Connect the DisplayPort Detective inline between your source device and display using standard DisplayPort cables. Power via included 5V/1A adapter or USB bus power during programming. The unit automatically captures and stores the connected display's EDID information upon first connection.​​

 

Operation (Automatic Maintenance)
Once programmed, the Detective maintains continuous EDID communication with your source, even when the display is powered off, switched away, or disconnected. Your computer always "sees" the display configuration, eliminating resolution resets, window repositioning, or black screen delays when displays come back online.​​

 

Customization (Advanced Control): Select from five factory EDID profiles using the 4-position DIP switch for instant compatibility with common display types. For custom requirements, connect via USB-C to program one of three user-programmable memory banks, allowing quick adaptation to unique system configurations. Enable the write-protect switch to lock configurations in production environments.
