4K High Speed HDMI Cable 100ft - Active CL2 In-Wall, 18Gbps

In this review the Monoprice 4K High Speed HDMI Cable 100ft is evaluated for consumers who need a long, in-wall rated cable for 4K sources. The bottom line: it is a well-built active HDMI cable that delivers 4K UHD over long runs when conditions match its directional design, and its CL2 in-wall rating and 18Gbps bandwidth make it a practical choice for installations where HDR and multichannel audio are required. The review focuses on real-world performance, construction, and limitations so you can decide if it fits your setup.

Key Features

• 18Gbps bandwidth: Provides ample throughput for 4K@60Hz sources and HDR formats in supported configurations.
• Active electronics: Built-in chipset boosts signal over the 100ft length to maintain a stable connection when used in the correct direction.
• CL2 in-wall rated: Cable jacket meets fire safety requirements for concealed residential runs, simplifying permanent installs.
• HDR and Dolby Vision support: Allows expanded contrast and color range for compatible sources and displays to improve picture quality.
• High-definition audio support: Passes multichannel formats including DTS-HD Master Audio and Dolby TrueHD for home theater setups.
• YCbCr 4:4:4 chroma: Preserves color fidelity and sharpness for PC and media content that benefits from full chroma sampling.

Who It's For

The cable is best for home theater installers, AV hobbyists, and anyone who needs a long run with a safe in-wall rating and expects to carry 4K video and high-definition audio across that distance. Its active design helps in situations where passive cables fail at similar lengths.

Buyers who need guaranteed 4K@60Hz in every environment or who prefer non-directional passive cables for simple plug-and-play may want to consider other shorter or certified alternatives. Also note that real-world performance can vary by source, display, and intermediary devices, so it may not resolve every signal issue.

Pros & Cons

Pros

• Sturdy construction and CL2 jacket make it suitable for concealed, permanent installations.
• Supports HDR formats and high-definition multichannel audio for a rich viewing experience.
• Active chipset and 18Gbps capacity improve chances of reliable 4K transmission over 100ft.
• Good value relative to other long active, in-wall rated HDMI options.

Cons

• Directional nature means it must be connected the correct way; some users report signal reliability issues at long distances.
• Mixed customer feedback about consistent 4K@60Hz performance in all setups suggests testing with your equipment first.
