How to use

Connect one HDMI Type A male end to the source device (player, game console, PC GPU) and the other HDMI Type A male end to the display or AV receiver. Ensure both devices support the desired resolution and refresh rate; if necessary, configure output settings in the source device to 8K @ 60Hz. Route the cable avoiding sharp bends and excessive tension to preserve the optical fibers.
