HDMI Cables

Match the cable to the highest resolution and features you need (e.g., 1080p, 4K@60Hz, 4K@120Hz, HDR, or 8K) and ensure it supports the HDMI version or feature set (such as HDMI 2.0 or 2.1 capabilities) required by your devices; also consider length and build quality to reduce signal loss over long runs

Standard HDMI supports up to 1080i/720p, High-Speed handles 1080p and many 4K@30Hz features, and Premium/Ultra High-Speed cables support higher bandwidths needed for 4K@60Hz HDR, 4K@120Hz, or 8K video and advanced features like eARC and VRR; choose based on the resolution and features your devices require

Longer passive HDMI cables can exhibit signal degradation; for reliable uncompressed performance, keep passive cables under about 3–10 meters (10–33 feet) depending on bandwidth needs, or use active HDMI cables, fiber HDMI, or HDMI extenders for longer runs

Choose HDMI with Ethernet only if you plan to use the cable to network-compatible devices via HDMI; eARC/ARC support is necessary if you want advanced audio return features and high-bitrate audio passthrough between a TV and soundbar or AV receiver

Check the cable’s specified bandwidth rating (e.g., 18 Gbps for many 4K@60Hz HDR features, 48 Gbps for 4K@120Hz and 8K), and look for explicit mention of the feature (HDR, VRR, eARC) or an 'Ultra High Speed' designation from manufacturers

For most users, a well-made cable that meets the required bandwidth and feature specs provides reliable performance; higher prices often reflect build quality, shielding, and brand, but do not change the HDMI protocol limits—buy based on needed specs and reputable construction

Avoid sharp bends and kinks, use gentle strain relief at connectors, keep cables away from strong electromagnetic sources, and choose appropriate-length cables to reduce unnecessary slack and potential signal issues
