This coupler supports up to 8K at 60Hz and 4K at 120Hz, provided that the connected HDMI cables and devices also support these specifications.

Yes, to achieve 8K 60Hz or 4K 120Hz performance, you must use Ultra High Speed HDMI cables rated for 48Gbps on both sides of the coupler.

You can join any HDMI cables, but for optimal performance with high resolutions and refresh rates (like 8K or 4K 120Hz), both cables must be Ultra High Speed certified.

This coupler is designed for passive signal transmission and should not introduce any noticeable delay for standard use cases.

The grey color is primarily aesthetic, helping the coupler blend discreetly into your entertainment setup.

It supports Ultra High Speed data transfer rates of up to 48Gbps.

Verify that both HDMI cables are securely plugged into the coupler and your devices. Ensure that both connected HDMI cables are rated for Ultra High Speed (48Gbps) and that your source and display support the desired resolution and refresh rate.

Check the connection points for any debris. Try swapping the HDMI cables to rule out a faulty cable. Ensure the cables are certified Ultra High Speed.

Confirm that your source device, the HDMI cables, and your display device all support the higher resolution (e.g., 8K 60Hz or 4K 120Hz). This coupler requires compatible cables and devices to pass through these advanced signals.
