What is the maximum range?

The device works up to 30 meters (98 feet) in open space. Walls, ceilings, and other obstacles can reduce range significantly.

How can I change the channel to reduce interference?

On both the transmitter and receiver, press the channel button to cycle through 4 channels. Ensure both units are on the same channel for proper operation.

Why is there no picture or sound?

Check that both units are powered on and the HDMI cables are firmly connected. Verify the TV input is set to the correct HDMI port. Also, ensure the pair is established.

Can I use this to stream from a laptop?

Yes, if your laptop has an HDMI output. Connect the transmitter to the laptop, and the receiver to your TV or monitor.
