Overview

The Monoprice 113589 Ultra Slim Active High-Speed HDMI Cable is engineered for installations where space is at a premium. Its zinc alloy connector heads measure just 0.63 by 0.26 inches — a fraction of the size of a standard HDMI plug — which makes it the go-to solution for wall-mounted TVs with recessed ports, tightly packed AV racks, or laptops with closely spaced connectors. The cable itself uses 36AWG conductors, resulting in an exceptionally thin and flexible profile that's easy to route through conduit, behind furniture, or along walls for a clean, invisible installation.

Despite its slim build, the cable doesn't compromise on performance. An active chipset built into the connector regenerates the signal to maintain a full 18Gbps data throughput, supporting 4K resolution at 60Hz, 3D video, and high-definition audio formats including DTS-HD Master Audio and Dolby TrueHD. The active design does mean the cable is directional — each end is designated for either the source or the display — so proper orientation during setup is essential. At 3 feet in length, this cable is purpose-built for close-proximity connections rather than long runs, making it ideal for desktop monitors, projector setups, or media consoles where the source device sits right next to the display.

Pros & Cons

👍 Pros

  • Ultra-slim connectors fit into recessed HDMI ports and tight spaces where standard plugs won't
  • Active signal regeneration maintains full 18Gbps bandwidth despite the thin cable profile
  • 36AWG conductors make the cable highly flexible and easy to route behind wall-mounted displays
  • Supports full 4K at 60Hz with high-definition audio passthrough
  • Zinc alloy connector heads add durability without adding bulk

👎 Cons

  • At only 3 feet long, it's limited to setups where the source and display are very close together
  • Active design means the cable is directional, requiring correct orientation during installation
  • Ultra-thin conductors are more fragile than standard gauge HDMI cables and require careful handling
  • Not suitable for use with HDMI switches or splitters that don't pass power to active cables
