Key Digital KD-Pro16 4K 18G HDMI Cable 16ft with HDR HDCP 2.2 and Ethernet

Key Digital KD-Pro16: Commercial-Grade 4K Reliability at 16 Feet

The Key Digital KD-Pro16 is a commercial-grade 4K/18G HDMI cable measuring 16 feet (4.9 m) between its two HDMI Type A male connectors. A commercial-grade cable is engineered with tighter shielding and conductor tolerances than a consumer patch cord, so it holds full bandwidth over a fixed installed run rather than a short desktop hop. That construction lets it serve as a dependable backbone between a source and a display, projector, or matrix switcher in a permanent install. Integrators reach for it wherever a 16-foot link cannot be allowed to sparkle, drop, or degrade over years of daily use.

Full 18Gbps Bandwidth for True 4K

18 Gbps of bandwidth carries Ultra HD/4K resolutions up to 4096x2160 and 3840x2160 at 60Hz with 4:4:4 chroma subsampling across the KD-Pro16. 4:4:4 chroma means every pixel keeps its own full color sample rather than sharing color data with its neighbors, which is what preserves fine text, thin lines, and saturated graphics. Because the cable provides the complete 18 Gbps pipe, that detail arrives at the display exactly as the source rendered it, with no downscaling of color resolution. Small on-screen text, CAD drawings, and fast motion therefore stay crisp all the way to the far end.

HDR and HDCP 2.2 Passthrough

HDR10 high dynamic range and HDCP 2.2 both pass intact over the KD-Pro16. HDR10 widens the range between the darkest and brightest parts of an image for more lifelike highlights and shadow detail, while HDCP 2.2 is the copy-protection handshake that modern 4K sources require before they will output protected content. Carrying both cleanly means protected 4K movies and streaming apps play without the handshake errors or blank screens a marginal cable can cause. The cable is also backward compatible with earlier HDCP versions, so it works with older sources on the same run.

Immersive Surround Audio and ARC

Surround formats up to Dolby 7.1, Dolby Atmos, and DTS-HD travel over the KD-Pro16 alongside the video. These object-based and multichannel formats place sound around and above a listener, and passing them intact preserves the full home-theater or presentation soundstage the source encodes. The built-in Audio Return Channel (ARC) additionally sends audio from a display back to a connected AV receiver or soundbar over the same cable, so a smart display's own apps can drive the room's sound. That two-way capability removes a separate audio cable and simplifies the wiring behind the display.

Fire-Rated Construction for In-Wall Runs

CL3 and FT4 fire-code ratings qualify the KD-Pro16 for in-wall routing where local electrical code requires a rated jacket. Those ratings certify that the cable's jacket resists flame spread inside a wall cavity, which is a legal requirement for permanently concealed AV cabling in most commercial buildings. Key Digital's OPEN EYE testing further certifies each cable for low signal loss and noise-free performance across its full length, and a 100 Mb/s Ethernet channel is available between HDMI-enabled endpoints. Together these let an integrator conceal the run safely and trust it to carry a clean 4K HDR signal for the life of the install.

Where the KD-Pro16 Fits

A 16-foot length suits the common case where a rack or credenza sits a short distance from a display, projector, or matrix switcher. Conference rooms, classrooms, houses of worship, and residential media rooms all use this reach to bridge a source location to a nearby screen without excess slack to manage. Because the cable is fire-rated and carries the full 18 Gbps pipe, an installer can pull it in-wall and forget about it rather than revisiting a marginal link. That reliability is why it is specified as the fixed HDMI backbone in permanent commercial installations.
