Overview

The Monoprice 139537 is a three-pack of 50-foot high-speed HDMI cables designed specifically for professional AV installers, contractors, and systems integrators. Each cable is deliberately unbranded — Monoprice leaves its name and logo off the product so that professionals can present them under their own brand during client installations. With a CL2 safety rating, these cables are approved for routing through walls and attic spaces in residential buildings, eliminating the need for conduit in standard home theater and commercial display setups.

Built with 24AWG 100% pure copper conductors and gold-plated connectors, each cable delivers 10.2Gbps of bandwidth — enough to handle 4K video at 24Hz, 3D content, deep color up to 48 bits, and multichannel uncompressed audio. The cables also support HDMI Ethernet Channel and Audio Return Channel for streamlined single-cable connectivity. The thinner conductor design and flexible CL2 jacket make these cables easier to pull through wall cavities and route around tight corners compared to bulkier alternatives, saving time on every install.

Key Features

Generic branding: Installers, contractors, and systems integrators need a reliable cable that they can make their own. We left our logo and name off these cables, so our brand is your brand.

CL2: These cables are safe for use in and through the walls and attic spaces of residential class buildings.

Thinner conductors: By using thinner conductors, these cables are easier to install, route, and hide from view.

CL2 High Speed HDMI Cables are the perfect solution for your high definition, multichannel audio and video needs. Featuring a 10.2Gbps bandwidth, these cables are capable of handling the 4K video resolution, 3D video, multichannel uncompressed audio, and all other features listed in the HDMI specification. The ultra-flexible, CL2-rated jacket combines with the thinner conductors and flexible jacket to produce a single key that fits every lock.

Supports the HDMI ethernet channel and audio return channel features. Deep color up to 16-bits per channel (48-bits total), including the Sony x.v.Color standard.
