ZDNET Names AmazonBasics $6 HDMI Cable Best of 2026 as Belkin Wins 48 Gbps Gaming Pick

Q: Are expensive '8K' HDMI cables an unnecessary upsell for most people with a 4K TV?

Yes. For most people with a 4K TV, expensive “8K” HDMI cables are largely an unnecessary upsell. The key issue is not the “8K” label but whether your equipment actually needs HDMI 2.1 bandwidth. Most streaming boxes, Blu-ray players, and many 4K TVs run at 4K/60Hz, which HDMI 2.0 handles just fine. In those setups, a certified, reasonably priced cable will deliver the same picture and sound as a much more expensive one. HDMI is digital: if the cable reliably carries the signal, paying more does not make the image sharper or colors richer. Where pricier “8K” cables can make sense is gaming and certain audio setups. If you have a PlayStation 5, Xbox Series X|S, or a high-end PC and a TV that supports 4K/120Hz, VRR, ALLM, or eARC, then an Ultra High Speed HDMI cable is appropriate. That is about unlocking specific HDMI 2.1 features, not about buying “8K” for its own sake. ZDNET’s 2026 testing reinforces that point. Its overall top pick was the AmazonBasics High-Speed HDMI cable at about $6 for 10 feet, praised for meeting standards and performing well. More expensive options were recommended mainly for specialized needs such as gaming, extra-long runs, or certified 48 Gbps support. For most buyers, the smart move is to match the cable to the device. Look for certified cables from reputable retailers, keep passive copper runs short when possible, and avoid paying a premium unless your TV and source devices actually require HDMI 2.1 features.

Q: Beyond official labels, how can you spot a poor-quality HDMI cable that is destined to fail?

A poor HDMI cable usually reveals itself through instability, weak build quality, and failure under real-world load, not just through missing labels. The clearest warning signs are performance problems: flickering screens, brief blackouts, “no signal” errors, random sparkles or pixel noise, audio crackling or dropouts, and devices falling back to lower resolution or refresh rates than they should support. If a cable claims to handle 4K120 or 8K but only works reliably at 4K60 or below, that is a practical sign it lacks the bandwidth or shielding for the job. Physical build also matters. Connectors that feel loose, wobbly, or cheaply made are a red flag, as are bent pins, frayed jackets, sharp kinks, or stress damage near the plug ends. Better cables tend to have sturdier connector housings, decent strain relief, and more durable shielding. Gold plating alone is not proof of quality, but flimsy construction often predicts early failure. Length is another giveaway. For passive copper HDMI cables, shorter runs are generally safer; around 6 to 10 feet is a sensible range for performance-critical setups. If a long passive cable is being used for high-bandwidth gaming or 8K video without active or optical support, signal degradation becomes much more likely. The most reliable test is simple: connect the source directly to the display, enable the highest intended settings, and swap in a known-good certified cable. If the problems disappear, the original cable was the weak link.

Q: With copper cables hitting their limits, will fiber optics soon replace them for everyday use?

Fiber optics are likely to complement, not soon fully replace, copper for everyday HDMI use. ZDNET’s 2026 cable review still points most consumers to inexpensive copper options, with the AmazonBasics High-Speed HDMI cable as the best overall pick and several other copper HDMI 2.1 cables recommended for gaming, streaming, and 8K support. That reflects today’s reality: for short runs in typical home setups, copper remains cheap, widely available, and good enough. HDMI 2.0 handles most streaming and 4K/60 gaming, while certified HDMI 2.1 copper cables can support 4K/120, VRR, ALLM, and eARC over short distances. Where copper is hitting limits is distance and signal stability. The same guidance notes that shorter runs are safer for passive copper, with roughly 6 to 10 feet ideal for performance-focused setups, and that beyond about 15 to 20 feet, users should consider active, optical, or extender-based solutions to avoid flicker, dropouts, and lag. That is where fiber optic HDMI is gaining ground, because it can carry 48 Gbps signals over much longer distances with less degradation and no electromagnetic interference. So the shift is already happening, but selectively. Fiber is becoming the preferred choice for long cable runs, high-end home theaters, multi-room AV, and demanding 4K/120 or 8K installations. For ordinary living-room connections, though, certified copper cables remain the practical standard because they are cheaper, simpler, and sufficient for most users.

ZDNET’s 2026 expert roundup picked AmazonBasics High-Speed HDMI as the best overall cable, citing reliable 4K performance, HDMI-and-Ethernet support, and a lifetime warranty.
At $6 for 10 feet, the AmazonBasics cable stood out on value while still delivering up to 18 Gbps bandwidth across lengths from 3 to 25 feet.
Belkin’s HDMI 2.1 Ultra High Speed took the gaming slot with 48 Gbps bandwidth, while Cable Matters and Zeskit were highlighted for longer runs and 8K-capable performance.
The review says HDMI 2.1 is usually unnecessary for general streaming, with HDMI 2.0 sufficient for 4K at 60 Hz, but higher-spec cables matter more for PlayStation and Xbox gaming.
