How to use

Connect one end of the cable to the HDMI output of the source device and the other end to the HDMI input of the display or AV receiver. Ensure both connected devices support the desired resolution and refresh rate and set the display settings on the source device to match. Route the cable along a safe path, avoiding tight bends and sharp edges that could damage the cable. If signal issues occur, verify input/output settings on connected devices and try a direct connection without additional adapters.

Recommendations

For reliable 8K@120Hz performance, use compatible source and display devices and confirm HDMI 2.1 features (such as bandwidth and refresh rate support) are enabled in device settings. When running the cable through walls or conduits, follow local building codes and avoid pinching or compressing the cable to maintain signal integrity.
