Notes & Compatibility

Look for the Ultra High Speed HDMI holographic label to ensure genuine 48Gbps certification. Passive copper cables are reliable up to 3m; longer runs should use active or fiber-optic versions — note that Active Optical Cables (AOC) can experience overheating at the conversion chips in connector heads, so ensure adequate ventilation. HDMI 2.2 (96Gbps, 'Ultra96' certification) has been announced for future devices requiring 4K@240Hz or uncompressed 8K@60Hz — this cable will not support HDMI 2.2 speeds.
