Overview of the CAB-HDMI-MUL4K-2M=
The CAB-HDMI-MUL4K-2M= is a 2-meter HDMI 2.0 cable certified for 4K Ultra HD (3840×2160) video transmission, designed to integrate with Cisco collaboration and digital signage systems. It ensures high-definition signal integrity for applications requiring precise visual fidelity, such as video conferencing or display walls.
Key Technical Specifications
- Resolution: Supports 4K@60Hz, HDR10, and 18 Gbps bandwidth for uncompressed video/audio.
- Compatibility: Works with HDMI 2.0/1.4 devices, including Cisco Room Kits and TelePresence systems.
- Durability: Reinforced braided jacket with gold-plated connectors to resist signal degradation.
- Audio: Transmits Dolby Atmos, DTS:X, and 32-channel PCM audio.
Core Applications in Cisco Ecosystems
This cable is tailored for:
- Collaboration Spaces: Linking Cisco Board Pro 55/75 displays to codecs for seamless video conferencing.
- Digital Signage: Driving 4K content across multiple screens in lobbies or control rooms.
- Training Centers: Delivering high-resolution instructional videos or live demos.
Addressing Common User Concerns
Q: Does it support HDMI ARC or Ethernet over HDMI?
The CAB-HDMI-MUL4K-2M= lacks HDMI Ethernet Channel (HEC) support but includes Audio Return Channel (ARC) for bidirectional audio between displays and sound systems.
Q: Is it backwards-compatible with older HDMI devices?
Yes, it maintains compatibility with 1080p@120Hz or 1440p@144Hz displays but prioritizes 4K clarity for modern Cisco hardware.
Why Opt for Cisco-Certified HDMI Cables?
Cheap third-party HDMI cables often fail to sustain 4K@60Hz over time due to inadequate shielding or bandwidth limitations. The CAB-HDMI-MUL4K-2M= guarantees stable performance in enterprise environments, avoiding flickering or signal drops.

Deployment Best Practices
- Length Limitations: For 4K@60Hz, avoid extending beyond 3 meters without signal boosters.
- Heat Management: Keep away from high-temperature sources (e.g., server exhausts) to preserve insulation.
- Bend Radius: Avoid sharp folds to protect internal wiring.
Final Perspective
In hybrid work environments, reliable AV connectivity is non-negotiable. The CAB-HDMI-MUL4K-2M= eliminates uncertainties in mission-critical setups—I’ve seen subpar cables derail executive briefings due to flickering or audio lag. While pricier than generic alternatives, it’s a strategic investment for maintaining professional-grade visual communication.
