- Confirm the display device is set to the correct HDMI input.
- Try re-pairing the units by pressing the STA/MirrorPair button on both devices.
- Reduce the distance between the Transmitter and Receiver, and remove any major obstructions.
- Poor Picture Quality/Intermittent Signal:
- Ensure antennas are securely attached and oriented for best reception.
- Minimize interference from other 5GHz wireless devices.
- Check the distance and line-of-sight between units. Walls, furniture, and other objects can degrade signal quality.
- Ensure the power supply is stable and sufficient for both units.
- Audio Issues:
- Verify audio settings on your source device and display.
- Ensure HDMI cables support audio transmission.
- Lag/Latency:
- While the device offers low latency, some minimal delay compared to a direct wired connection is inherent in wireless transmission. This product is not recommended for gaming where ultra-low latency is critical.
- Ensure optimal signal strength as described above.
