Crestron CBL-8K-HD-12 – HDMI 2.1 Cable, 48 Gbps, 12 ft

Product Overview

The Crestron CBL-8K-HD-12 is a 12-foot (3.6m) Ultra High Speed HDMI 2.1 certified cable rated at 48 Gbps — supporting 8K60, 4K120, and 4K60 4:4:4 HDR10+ uncompressed video alongside eARC, VRR, and ALLM for commercial AV installations requiring the highest available HDMI bandwidth. Crestron-certified for commercial AV use, it is specified where full HDMI 2.1 bandwidth is required between source devices and displays: 8K digital signage, 4K120 gaming and broadcast monitoring displays, and high-frame-rate commercial visualization environments. The 12-foot length covers standard rack-to-display and equipment-to-display connection distances in commercial AV rooms.

Product Description

HDMI 2.1 at 48 Gbps represents the current practical ceiling of HDMI signal bandwidth — three times the 18 Gbps of HDMI 2.0 — enabling 8K resolution, 4K at 120fps, and uncompressed 4K60 4:4:4 HDR10+ in applications where HDMI 2.0 bandwidth limitations force color subsampling or frame rate compromises. In commercial AV installations, HDMI 2.1 cable is specified primarily in broadcast monitoring and production environments using high-frame-rate displays, digital signage or command center installations deploying 8K display technology, and commercial gaming or simulation facilities requiring 4K120 signal integrity. The CBL-8K-HD-12 is Ultra High Speed HDMI certified — the HDMI Forum’s certification program that validates cable construction, connector quality, and 48 Gbps bandwidth performance through independent testing. Crestron certification adds validation specific to Crestron AV system environments. The 12-foot length is appropriate for display connections in standard commercial rooms where shorter runs are expected from the rack or wall plate to the display.

Key Features

• HDMI 2.1 Ultra High Speed, 48 Gbps: Full 48 Gbps bandwidth supports 8K60, 4K120, 4K60 4:4:4 HDR10+, and all lower-bandwidth HDMI resolutions — the highest HDMI bandwidth available for future-proof commercial AV signal chains.
• 8K and 4K120 Support: Passes 8K60 and 4K120 uncompressed video for 8K digital signage, broadcast monitoring, high-frame-rate commercial visualization, and simulation display applications.
• Ultra High Speed HDMI Certified: HDMI Forum Ultra High Speed certification validates 48 Gbps performance through independent testing — ensures the cable meets published HDMI 2.1 specification rather than relying solely on manufacturer claims.
• eARC, VRR, ALLM Support: Supports HDMI 2.1 advanced features including Enhanced Audio Return Channel (eARC), Variable Refresh Rate (VRR), and Auto Low Latency Mode (ALLM) for commercial applications requiring these signal types.
• 12-Foot Fixed Length: 12 ft (3.6m) — covers standard display-to-rack and equipment-to-display connection distances in commercial AV rooms requiring HDMI 2.1 bandwidth.
• Crestron Certified: Engineered and tested for commercial AV use in Crestron AV systems — specified with confidence alongside Crestron HDMI 2.1-compatible AV equipment.
• Backward Compatible: Fully backward compatible with HDMI 2.0, HDMI 1.4, and all earlier HDMI versions and resolutions.

Typical Applications

• 8K digital signage and command center display connections from 8K media player or PC sources at short rack-to-display distances
• Broadcast monitoring facility connections from 4K120 or 8K production equipment to monitoring displays
• Commercial simulation and visualization facilities requiring 4K120 signal integrity between compute sources and high-frame-rate displays
• Corporate and government command center video walls with 8K or 4K120 source connections
• Commercial AV equipment rack-to-display connections in any environment where HDMI 2.1 bandwidth is required or anticipated

Frequently Asked Questions

Do I need HDMI 2.1 cable for a 4K60 4:4:4 HDR installation?
For 4K60 4:4:4 HDR at shorter distances (under 10 feet), a quality HDMI 2.0 18Gbps cable may be sufficient. At longer distances or where certified 48 Gbps performance is required for 8K or 4K120, HDMI 2.1 cable is required. For most commercial conference room 4K60 4:4:4 installations, a certified 18 Gbps HDMI 2.0 cable is the standard specification unless 8K or 4K120 is specifically required. Contact Creation Networks for cable specification guidance for your specific source and display combination.

Is a 3-foot version available?
Yes — the CBL-8K-HD-3 is the 3-foot (0.9m) HDMI 2.1 cable for short rack-internal or equipment-to-equipment connections. Contact Creation Networks for both lengths.

What is the warranty on the Crestron CBL-8K-HD-12?
Crestron provides a standard warranty on CBL-8K-HD series cables. Contact Creation Networks for warranty details.
