* 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

* Industrial Cameras

* Wireless Casting Devices

* Microscopes

* Medical Equipment

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