Setup, Compatibility & Care
For the best performance, ensure the cable is firmly seated in the HDMI ports of both your source device and display. Because HDMI 2.1 cables carry high amounts of data, avoid bending the cable at sharp angles or pinching it behind furniture, as this can stress the internal wiring.
This cable is fully backward compatible, meaning you can use it with older 4K or 1080p devices without issue, though you will only experience the performance benefits if both your hardware and your content support HDMI 2.1 standards. When cleaning, use a dry microfiber cloth to wipe the exterior of the cable and the connectors; avoid using liquid cleaners or heavy solvents near the ports.
