8. Troubleshooting
- Is this a wireless HDMI transmitter? No, this is a virtual display emulator (dummy plug). It does not transmit video signals and has no output port.
- Does it support high refresh rates like 144Hz? It is optimized for stability at 60Hz (4K/1080P). It is not recommended for high-refresh-rate gaming monitoring beyond its specified capabilities.
- Will it work with my Mac mini? Yes, it is fully compatible with macOS, Windows 10/11, and Linux. Ensure your Mac mini model has an HDMI output port, as this product connects via HDMI.
- No virtual display detected? Ensure the dummy plug is fully inserted into the HDMI port. Verify that your graphics card drivers are up to date. Restart the system if necessary.
