Compatibility Highlights:

* No screen flickering with NVIDIA RTX 50 Series GPUs.
 * Fully compatible with modern laptops.
* Certain RTX 5070 Ti and higher GPUs, as well as some newer laptops, may require switching to 12G×4 mode.

 

New Feature: Integrated Video Capture

 

The DC505 includes a built-in video capture function, eliminating the need for a separate capture card in many applications.

 

Capture Performance
* Up to 1080p @ 60Hz capture
* Ultra-low latency operation
* Simultaneous video and audio capture

 

Flexible Capture Modes

Users can:
* Capture the source device directly
* Capture the fused display output
* Stream and record while using display fusion simultaneously

 

This makes the DC505 ideal for:
* Live streaming
* Content creation
* OBS workflows
* Gaming setups
* Professional demonstrations

 

New Feature: EDID Injection & Editing (Mode C)

 

The DC505 introduces advanced EDID management capabilities for professional users and specialized equipment environments.

EDID Injection

 

Users can inject virtually any compatible EDID profile to improve compatibility between source devices and displays.

EDID Editing

 

The DC505 can read, modify, and write EDID data, including:

* Display ID
* Serial Number
* Monitor Name
* Display Model Information
* Manufacturer Information
* Other EDID parameters

 

After modification, the customized EDID can be written back and applied to the system.

Typical Applications

* Display compatibility optimization
* Industrial equipment integration
* Medical imaging systems
* Signal testing and validation
* Custom monitor emulation
* Professional AV environments

 

EDID Operating Modes

 

Mode A – Adaptive Timing EDID (Automatically adjusts timing parameters for maximum compatibility)

Benefits:

* Automatic signal optimization
* Broad device compatibility
* Plug-and-play operation

Note: Some early production units may display Mode A and Mode B labels in reverse. This can be corrected through future firmware updates.

 

Mode B – Native Monitor EDID (Uses the monitor’s original EDID information)

Benefits:

* Preserves factory display parameters
* Maintains native monitor behavior
* Ideal for users requiring original display characteristics

 

Mode C – Custom EDID Injection. (Provides complete EDID customization)

Features:

* Custom EDID loading
* EDID editing and writing
* Display identity emulation
* Enhanced compatibility control

 

Supported Devices

 

The DC505 currently supports a wide range of devices, including:

* Desktop PCs
* Laptops
* NUCs

 

Additional device compatibility continues to be expanded through ongoing development and firmware updates.
