Liberty AV HDPMM20F 20' Liberty Premium High Speed HDMI Cable with Ethernet Certified 18G

Product Overview

The Liberty AV HDPMM20F is a 20-foot Premium High Speed HDMI cable certified for 18Gbps bandwidth, supporting 4K/60Hz video with HDR and HDCP 2.2 at extended run distances in commercial AV installations. The 20-foot length is appropriate for larger conference rooms, training rooms, and AV installations where display walls, ceiling-hung projectors, or rack locations require longer HDMI cable runs than typical patch cables provide. Built to HDMI 2.0 standards with triple shielding, this cable maintains signal integrity over its full 20-foot run in commercial infrastructure environments.

Product Description

The HDPMM20F delivers full HDMI 2.0 performance over a 20-foot passive run, which represents the practical upper limit of reliable 18Gbps passive HDMI cable performance for 4K/60Hz signals. At this length, cable quality and shielding become critical factors, which is why Liberty AV's Premium series uses triple shielding to maintain signal integrity and suppress EMI from adjacent cable runs. The 20-foot cable handles 4K Ultra HD at 60Hz, HDR10 and Dolby Vision, HDCP 2.2, and multi-channel audio up to 32 channels. This is the appropriate length for AV system designs in medium-to-large conference rooms where the AV rack is located across the room from the primary display, for ceiling-hung projectors in classrooms, or for digital signage installations where source equipment is remote from the display. HDCP 2.2 compliance enables use with 4K UHD Blu-ray, streaming, and other protected content sources in commercial AV and hospitality environments. The cable is backward compatible with HDMI 1.4 and earlier for mixed-generation AV systems. ARC and CEC support enables audio routing and device control in integrated conference room AV designs. Both connectors are standard full-size Type-A male, compatible with all commercial AV equipment. For AV integrators planning long-run HDMI infrastructure, the HDPMM20F is the appropriate choice before considering HDMI extender solutions; runs beyond 20 feet at 18Gbps/4K60 will typically require an active optical cable or HDMI extender system.
