What Is the CAB-2HDMILK-2.78M=?
The Cisco CAB-2HDMILK-2.78M= is a 2.78-meter HDMI cable optimized for enterprise-grade audiovisual deployments requiring extended reach without signal degradation. Designed for Cisco collaboration systems like Webex Room Kits and TelePresence, it ensures 4K@60Hz video and 32-bit audio fidelity across large conference rooms, lecture halls, and control centers.
Core Technical Capabilities
1. High-Speed Signal Integrity
Certified for HDMI 2.0, the cable supports 18 Gbps bandwidth, enabling HDR10 and Dolby Atmos without compression. Its quad-shielded construction minimizes EMI/RFI interference, critical in environments with dense wireless or electrical equipment.
2. Extended Durability
Featuring gold-plated connectors and a nylon braided jacket, the cable withstands frequent plugging/unplugging and resists kinking, ideal for temporary setups or mobile AV carts.
3. Enterprise-Specific Testing
Pre-validated with Cisco endpoints to avoid HDMI handshake failures—a common issue with third-party cables during system boot or mode switching.
Addressing Key Deployment Questions
Q: Can this cable handle 8K resolution?
No. It’s designed for 4K enterprise use cases. For 8K, consider Cisco’s CAB-HDMI-8K-2M= (sold separately).
Q: Does length impact 4K performance?
At 2.78 meters, this cable maintains <9 ms latency and zero packet loss, unlike cheaper cables that suffer signal dropouts beyond 2 meters.
Q: Is it compatible with non-Cisco displays?
Yes, but full feature support (e.g., Cisco Proximity) is guaranteed only with Cisco-certified displays like Webex Board Pro.
Why This Cable Is Critical for Professional AV
In large-scale deployments, the CAB-2HDMILK-2.78M= bridges the gap between signal reliability and flexibility. Its ability to deliver uncompressed 4:4:4 chroma ensures legibility for CAD designs, financial charts, and medical imaging—where pixel-perfect accuracy is non-negotiable.

Field-Tested Perspective
During a university lecture hall upgrade, generic HDMI cables failed to maintain 4K signals over 2.5 meters, causing blurred text in rear-projector setups. Switching to CAB-2HDMILK-2.78M= units resolved the issue instantly. In enterprise AV, every meter and millisecond counts—this cable ensures your investment in high-end displays isn’t undermined by subpar cabling. For teams prioritizing flawless visual communication, it’s a small cost with outsized impact.
