Why choose our 4K wireless hdmi transmitter and receiver?

Because our products are true 4K transmitters and receivers, providing 4K decoding and 4K output, unlike other brands’ products that only provide 4K decoding and 1080P output.

The TX and RX lights are flashing normally, but the monitor is showing no picture. How can I troubleshoot this?

Connect another device, such as a DVD player or set-top box, to the TX to rule out the original signal source. Also, connect a different monitor to the RX to confirm that the monitor itself isn’t the problem. (See the product manual for details.)

Why is the image partially normal and partially distorted?

When streaming from a set-top box (such as a Sky box), you can adjust the output image resolution from 1080i or 2160i to 1080p or 2160p progressive scan video format through the function menu.

Why does this wireless HDMI kit require a power supply?

Connecting a 5V/2A power supply makes the connection between the wireless HDMI transmitter and receiver more stable.

Why doesn’t the wireless hdmi extender reach the claimed distance?

This 4K wireless hdmi extender requires stable and high-strength signal support. It is necessary to minimize obstructions between the TX and RX,and avoid placing the product in enclosed spaces (such as drawers or behind the TV).
