The missing link between budget USB-HID LED controllers and the professional HyperHDR ecosystem.
A lightweight, native C# WPF application that bridges cheap proprietary USB LED strips (SyncLight / PC Screen Sync) with the professional open-source Ambilight ecosystem of HyperHDR.
This software is specifically designed for Chinese USB Ambilight kits that use the HID protocol.
- VID:
0x1A86| PID:0xFE07 - Common Brands: Skydimo, SyncLight, Ambilight PC Kit.
- Device Look: Small controller with 3 physical buttons (Static modes, Power, Music modes).
If you own this hardware, you know the pain: the official "SyncLight" app is resource-heavy, laggy, and often fails to capture HDR content.
HdrBridge is a lightweight native C# replacement. We reverse-engineered the USB HID protocol (sniffing packets, cracking checksums, and handling remote interrupts) to give you a professional-grade experience. No more bloat, just pure performance.
- 🚀 Zero-Bloat: Built with .NET 8, focusing on minimal CPU/GPU overhead.
- 🔘 Physical Remote Sync: Unlike other apps, HdrBridge listens to your physical remote. Press "Power" on the cord, and the app automatically pauses HyperHDR streams.
- 🔧 Auto-Healing: Robust USB monitoring — plug or unplug your device, and the bridge recovers instantly.
- 👻 Tray Resident: Runs silently in the background with auto-start capability.
- 🌿 Smart Eco-System: Intelligent auto-power management. The LEDs won't waste their lifespan when you are away or when your display enters power-saving mode.
- 🎛️ Hardware Effect Control: Trigger the strip's built-in hardware effects (Rainbow, Breathing, Static Colors) directly from the app.
- HyperHDR captures your screen (DirectX/HDR) and sends RGB data via UDP (port 19446).
- HdrBridge intercepts the UDP stream, calculates the proprietary 332-byte chunks, and signs them with the required checksums.
- HID Communication: The bridge fires raw commands to the controller, bypassing the need for any Chinese drivers.
- Download
HdrBridge.zipfrom the latest Releases. - Run
HdrBridge.exe(Ensure .NET 8 Desktop Runtime is installed). - Set your HyperHDR output to
udpraw, IP127.0.0.1, Port19446. - The app will automatically detect your LED strip and initialize it.
- Enjoy a smooth, professional Ambilight experience.
In the HyperHDR web interface, set the LED Hardware as follows:
- Controller Type:
udpraw - Target IP:
127.0.0.1 - Port:
19446 - Important: Adjust the Input Position or Reverse Direction in the LED Layout settings to match your physical LED strip start.
If you prefer a minimal CLI approach or need a code reference for the protocol, we've included node_strip_test.js. It is a bare-bones script that:
- Initializes the USB device.
- Starts a UDP server on port
19446. - Directly forwards RGB data to the strip without UI or complex logic.
How to run:
- Install Node.js.
- Install the HID dependency:
npm install node-hid. - Run the script:
node node_strip_test.js.
Feel free to open issues or submit pull requests if you discover new hardware effect IDs or want to improve the UI!
