Couldn't load pickup availability
The DICHEN Flagship Video Fuser (Model: DC1A686-D3ZC) represents the pinnacle of professional-grade hardware signal processing and multi-display fusion. Built on a next-generation hardware-level interconnection architecture, it enables direct, lossless signal communication between two independent host computers and your primary display without adding latency or visual compression.
Designed for demanding esports environments, multi-system workstations, and professional broadcasting, the DICHEN Flagship eliminates the need for manual EDID flashing with Native EDID Automatic Passthrough and one-click hardware ID customization. Whether you are running mismatched resolutions across your primary and secondary rigs (such as 2K 360Hz + 1080p 360Hz) or pushing extreme competitive frame rates up to 639Hz at 1080p, this unit guarantees rock-solid stability across 99% of monitors on the market.
SUPPORTED RESOLUTIONS & REFRESH RATES
Engineered to maximize full DisplayPort 1.4 bandwidth with support for RGB/YCbCr color modes and 8-bit, 10-bit, and 12-bit color depth:

| 1280 × 720p (HD) | 1 – 1000Hz+ (Theoretical Peak: 1350Hz+) |
| 1920 × 1080p (FHD) | 1 – 639Hz |
| 2560 × 1440p (QHD / 2K) | 1 – 364Hz |
| 3440 × 1440p (Ultrawide) | 1 – 264Hz |
| 3840 × 2160p (4K UHD) | 1 – 164Hz |
| 5120 × 1440p (Super Ultrawide) | Unlockable via future firmware update |
FEATURE BREAKDOWN
SIGNAL ARCHITECTURE & PROTOCOL SUPPORT
Triple Full-Bandwidth DP 1.4: Equipped with three high-speed DisplayPort 1.4 transmission interfaces operating at full system bandwidth for lossless, uncompressed image output.
Low-Level AUX Protocol Suite: Full hardware-level support for DLSS, DDC, HPD, EDID, HDCP, MST, and FEC protocols, ensuring fast, stable handshaking without abnormal communication errors.
99% Display Compatibility: Rigorously tested across 62 display models from major brands. Deep low-level protocol tuning allows both high- and low-spec host systems to maintain stable high-refresh performance.
FLAGSHIP EXCLUSIVE CAPABILITIES
Native EDID Automatic Passthrough: Automatically reads and passes through your monitor's native EDID profile—no complex manual dumping or injection required.
One-Click Display ID Customization: Instantly customize and generate new display serial numbers and hardware IDs with permanent onboard memory storage.
Mixed-Resolution & Intelligent Scaling: Simultaneously output different resolutions from your primary and secondary PCs (e.g., stable 2K 360Hz + 1080p 360Hz operation), or scale a 2K display down to support ultra-high-refresh 1080p output specs.
Capture Card Live Streaming: Dedicated Flagship support for seamless integration with external capture cards for zero-interference live streaming and recording.
DUAL-HOST OPERATION & FUTURE-PROOFING
One-Touch Dual-Host Switching: Instantly toggle between two connected host PCs with zero signal degradation, allowing both systems to operate independently under heavy loads.
Serial-Port Firmware Upgradability: Built-in official serial upgrade interface ensures long-term value through continuous performance iterations and future resolution unlocks (including 5120 × 1440p support).
Disclaimer: The DICHEN DC1A686-D3ZC is a professional hardware device designed strictly for high-definition video signal fusion, multi-display switching, high-refresh-rate adaptation, and signal passthrough across commercial, office, broadcasting, and entertainment applications. It operates purely on video display signals and does not read system memory, modify programs, or provide any software-level functionality.
