5. Operating Instructions
Once installed, the HDMI dummy plug operates automatically by emulating a connected display.
- Remote Access: Connect to your headless computer using remote desktop software (e.g., VNC, TeamViewer, AnyDesk). The virtual display will ensure that the remote session operates at the desired resolution and refresh rate, providing a smoother experience.
- GPU-Intensive Tasks: For applications that require an active display to fully utilize the GPU (e.g., rendering, scientific computing, cryptocurrency mining), the dummy plug ensures the graphics card remains fully engaged.
- Virtual Display Management: In your operating system's display settings, you can manage the virtual display as you would a physical monitor, including setting its resolution and arrangement relative to other displays (if any).
