6. Troubleshooting
If you encounter issues, please refer to the following common troubleshooting steps:
- No Display/Signal:
- Ensure both TX and RX units are properly powered and their LED indicators show a stable connection.
- Verify that the HDMI cables and adapters are securely connected to both source and display devices.
- Check the input source on your display device (TV/monitor) is set to the correct HDMI input.
- Reduce the distance between the TX and RX units and remove any obstructions. Walls and obstacles can significantly reduce transmission range.
- Intermittent Signal/Poor Quality:
- Ensure there are no strong interference sources (e.g., other 5G Wi-Fi devices, microwaves) nearby.
- Relocate the TX/RX units to improve line-of-sight if possible.
- Check the signal strength indicator on the LED screen. If it's low, try moving the units closer.
- Audio/Video Sync Issues:
- While the device is optimized for video and general use, some users have reported potential sync issues or pixelation with high-frame-rate content like gaming consoles. This device is primarily designed for streaming video and presentations rather than competitive gaming.
- Units Not Pairing:
- Power cycle both the TX and RX units by unplugging and re-plugging their power cables.
- Ensure both units are within effective transmission range.
