1. Introduction
The FUERAN HDMI 2.1 Dummy Plug is a virtual display emulator designed to simulate a connected display on your computer's HDMI output. This device is particularly useful for systems operating in a 'headless' configuration (without a physical monitor) or for tasks requiring GPU acceleration and high-resolution remote desktop access.
It tricks the graphics processing unit (GPU) into detecting a connected display, enabling the GPU to remain active and render at high resolutions, which is crucial for various applications including remote desktop, server management, and cryptocurrency mining.

2. Setup
The FUERAN HDMI 2.1 Dummy Plug is designed for simple plug-and-play operation. No software installation, drivers, or external power supply is required.
2.1 Installation
- Locate an available HDMI output port on your computer or graphics card.
- Insert the FUERAN HDMI 2.1 Dummy Plug firmly into the HDMI port.
- The system should automatically detect the virtual display.
2.2 Compatibility
This device is compatible with any HDMI-capable PC and supports various operating systems, including Windows, macOS, and Linux.

3. Operating Instructions
Once installed, the dummy plug emulates a high-definition display, allowing your computer's GPU to function as if a monitor is connected. This enables several key functionalities:
- Remote Desktop Access: Achieve high-resolution remote desktop sessions (e.g., via TeamViewer, AnyDesk, VNC) without a physical monitor, preventing issues like black screens or limited resolutions.
- GPU Acceleration: Maintain full GPU functionality for tasks such as cryptocurrency mining, video rendering, simulations, and other GPGPU operations.
- Virtual Display: Create a virtual second screen that can be cast to other devices or used for extended desktop environments in headless setups.

4. Maintenance
The FUERAN HDMI 2.1 Dummy Plug requires minimal maintenance. Keep the device clean and free from dust. Avoid exposing it to extreme temperatures or moisture. Handle with care to prevent physical damage to the connector.
5. Troubleshooting
- No Virtual Display Detected: Ensure the dummy plug is fully inserted into the HDMI port. Try a different HDMI port if available. Restart your computer.
- Incorrect Resolution/Refresh Rate: While the dummy plug enables high resolutions, the actual resolution and refresh rate supported depend on your graphics card and its drivers. Check your operating system's display settings to adjust the resolution.
- Remote Desktop Issues: Ensure your remote desktop software is correctly configured and that network connectivity is stable.
- HDCP Compatibility: Please note that this device DOES NOT SUPPORT HDCP (High-bandwidth Digital Content Protection). This means it may not work with content or devices that require HDCP for playback.

7. User Tips
- For macOS users, an OSX utility like 'Display Menu' can simplify changing resolutions when using the dummy plug.
- This device is highly effective for headless Raspberry Pi setups, allowing VNC displays to operate at full resolution.
- When using for cryptocurrency mining, the dummy plug helps ensure that the graphics card is 'detected' as having a monitor plugged in, which can prevent features like HBCC (High Bandwidth Cache Controller) from disabling.
- The dummy plug provides a stable solution for remote access compared to some software-only virtual display options.
8. Warranty & Support
