1. Introduction
The FUERAN 4K-1P HDMI Dummy Plug is a compact device designed to emulate a connected display, allowing a computer to operate as if a monitor is attached, even when it is not. This is particularly useful for remote desktop applications, server management, cryptocurrency mining, and other headless operations where a physical display is not required but a graphics output signal is needed for proper system function and resolution management.
This emulator supports high resolutions up to 3840x2160@60Hz and 1080@120Hz, ensuring that your system's graphics card operates at its full potential, preventing issues like black screens, screen freezing, or low resolution when accessed remotely.

- Ensure the dummy plug is fully inserted into the HDMI port.
- Try a different HDMI port on your graphics card or computer.
- Restart your computer after inserting the dummy plug.
- Update your graphics card drivers to the latest version.
- Low Resolution or Incorrect Refresh Rate:
- Access your operating system's display settings and manually adjust the resolution and refresh rate.
- Verify that your graphics card supports the desired resolution and refresh rate.
- Some remote desktop software may have limitations on resolution; check its settings.
- Remote Desktop Issues (Black Screen, Freezing):
- Ensure the dummy plug is securely connected.
- Confirm that your remote desktop software is configured correctly and supports the emulated resolution.
- The dummy plug is designed to prevent these issues by activating the GPU; if they persist, check your remote software or network connection.
- Not an HDMI Transmitter/Receiver: This device is an emulator, not for transmitting or receiving video signals. It does not support HDCP.
