4K HDMI 2.0 Cable 100ft with Built-In Signal Booster - Directional

In this review the LZCT 4K HDMI 2.0 Cable 100FT is judged on long-run video reliability and signal integrity for long runs. The bottom line: this cable is aimed at users who need a single-direction long HDMI run with a built-in IC booster and consistent 4K support; its biggest selling point is the stable transmission over long distances thanks to the booster and heavy shielding. For anyone wiring a projector, home theater, or long-distance display where a reversible passive cable would fail, this cable delivers predictable results when connected the right way.

Key Features

• HDMI 2.0 with Ethernet: Supports Ultra HD 4K@50/60Hz (2160P) and provides a networked HDMI path when equipment supports HDMI Ethernet Channel.
• Built-in signal booster: The directional IC booster preserves picture and audio clarity over the full 100ft length when input and output ends are connected correctly.
• High bandwidth and color depth: 18 Gbps bandwidth and 48-bit color depth maintain high-fidelity video and deep color for HDR-capable sources and displays.
• Robust construction: Gold-plated contacts, 99.99% high-purity OFC conductor and triple shielding minimize signal loss and resist interference in long runs.
• Wide compatibility: Backward compatible with HDMI 1.4/1.3 and supports common devices such as Blu-ray players, consoles, set-top boxes, PCs and projectors.
• ARC and audio support: Supports Audio Return Channel and Dolby TrueHD 7.1 for multichannel audio over the same cable.

Who It's For

This cable is best for home theater installers, AV hobbyists, and anyone who needs a reliable single-direction HDMI run longer than typical consumer cables - for example connecting a distant projector or a wall-mounted TV to a media rack. The built-in booster and heavy shielding make it a practical choice where signal drop and interference are concerns.

It is not ideal for users who need a reversible or bidirectional active cable or those requiring full 4K/60Hz at YUV444 color sampling; the 100ft directional design requires correct orientation and has format limits at the highest color sampling. If you need full 4K/60 YUV444 over 100ft, a fiber HDMI solution or active bidirectional extender would be a better match.

Pros & Cons

Pros

• Very stable long-distance signal thanks to the IC booster and triple shielding.
• Supports 4K@50/60Hz, HDR, ARC and Dolby TrueHD audio for modern AV setups.
• Durable build with gold-plated contacts and oxygen-free copper for longevity.
• Works with a wide range of HDMI devices and is backward compatible with older HDMI versions.

Cons

• Directional one-way design must be connected correctly; misuse will result in no signal.
• Does not support 4K/60Hz at YUV444 over the longest runs, only up to 4K/60 under YUV420 or 4K/30 YUV444.

Our Verdict

For long-run HDMI needs this LZCT 4K HDMI 2.0 Cable 100FT is a practical, value-focused option: it combines an IC booster, heavy shielding and quality conductors to preserve 4K and multichannel audio across 100ft when connected in the correct direction. Installers and AV users who understand the directional limitation will find it a reliable and cost-effective way to extend modern HDMI signals without complex extenders.

Frequently Asked Questions

Is the cable reversible?
Answer. No, the 100ft version is directional and the input end must be connected to the source while the output end goes to the display for the booster to work.

Will it do 4K/60Hz at full color depth?
Answer. It supports 4K/60Hz under YUV420 and 4K/30Hz at YUV444; it does not support 4K/60Hz at YUV444 on long runs.

Does it support Ethernet and ARC?
Answer. Yes, the cable supports HDMI Ethernet Channel and Audio Return Channel when both source and display support those features.
