How to use
Connect one end of the HDMI cable to the HDMI output of your source device (such as a Blu-ray player, gaming console, PC or AV receiver) and the other end to the HDMI input of the display device (TV, monitor or projector). Ensure both devices are powered off when plugging in to avoid hot-plugging issues, then power them on and select the corresponding HDMI input on the display. Use device settings to enable desired resolution and refresh rate; if the display and source support 8K or high-frame-rate modes, select these options in the device menus.
Usage recommendations
For optimal performance over 20 metres, route the cable away from large sources of electromagnetic interference (power cables, transformers) and avoid sharp bends. If you experience signal limitations at the highest resolutions or refresh rates, verify that both source and display fully support HDMI 2.1 features and set the appropriate modes in device settings.
