Client Case Sharing: 8K Signals to the Future in a 50-Meter Historic Theater Retrofitted
The Brief: 8K Projection Preserves Architecture in UPGRADING Heritage Cinema
Technical Challenge: A high-end multi-discipline restoration project on a historic 1920s cinema underwent an angelic makeover. To ensure the original projection booth is maintained as a heritage-protected structure, a 50m fiber run connected the new 8K laser projector, installed in the booth, to a newly built basement control room housing both a digital media server and an audio processor. The client needed a way to deliver perfect 8K@60Hz HDR and Dolby Atmos audio signals over this distance without altering the building’s historic fabric by installing large conduits. The old conduit was a narrow one and already partly full. The installers required an in-wall-rated HDMI cable that was extremely thin and flexible and that could be run over a distance of 100+ meters while adhering to very strict local fire safety codes for the venue.
BespokeCable Solution: Use the 4.5mm Fiber Optic In-Wall HDMI System
After reviewing both active copper and HDMI-over-fiber extender kits, the customer team selected our In-Wall HDMI 2.1 Cable with dual removable heads as the only neat-and-tidy solution. The design specifically responded to every constraint:
- Ultra-thin, code-compliant pull: Thanks to a 4.5mm-diameter, CL2-rated cable jacket and Kevlar-reinforced core, the team was able to fish the cable through existing ¾-inch conduit shared with other low-voltage wiring—something that would have been impossible with any standard round active cable.
- Why Detachable Head Pivotal: It had dual micro HDMI and was fully detachable. First, the thin cable body was pulled through. In the large equipment rooms, equipped with robust, firmly attached active heads, the risk of damaging the sensitive German Silicon Line photoelectric chips during the demanding pull was eliminated.
- Reliable Over Longer Distances: As a pure fiber-optic HDMI cable, it transmitted 8K/60Hz signals over the entire 100m run losslessly, with zero latency, artifacts, or EMI interference from the venue’s extensive lighting and power systems.
The Final Execution and Results: A Smooth High-Fidelity Result
The installation process went very smoothly. The signal indicator lights on each interface could immediately indicate that everything was normal. At the grand reopening ceremony, the projector presented 8K historical images and the latest content with perfect clarity. Equipped with the QMS (Quick Media Switching) function, it can effectively support multi-generation video display at 48 Gbps. The eARC function can also perfectly synchronize object-based audio to the new Dolby Atmos system.
But, thankfully, the historic structure was preserved. “This is essentially the only solution to meet not only the performance demand but also the physical limitations and our green mandate,” said the project’s architect. Installation as invisible as the image it was making possible.

A Professional Guide for AV Integrators of In-Wall HDMI Cable
Installing this cable(s) in a wall should be done carefully, with attention to its longevity and compliance with building codes. In contrast to standard patch cords, in-wall-rated HDMI cables are designed for permanent installation behind drywall or within conduits. Using this unique head design for a flawless setup, this guide covers the professional way to install BespokeCable’s In-Wall HDMI 2.1 Cable in residential and commercial projects where neat integration is essential.
Step1: Planning (Compliance check before installation)
Be sure to check local building codes before running any cable. This is our CL2-rated jacket, designed for in-wall applications and meeting the fire safety requirements for residential & light commercial environments. Ensure that, for 8K@60Hz or 4K@120Hz over very long distances (up to 100m), the path avoids sharp bends and maintains a distance from AC power lines to minimize EMI interference. When planning the pathway, identify a conduit run through which the 4.5mm slim diameter must pass from the source (media closet/AV receiver) to the display location.
Step 2: Taking advantage of the detachable head for pulling conduit
The dual detachable micro HDMI design is the main highlight, enabling simpler installation. For Tight Conduit Setups or In-conduit wiring
- Remove the heads: Pull out and Store Properly.
- Pull the Cable: Connect the thin, reinforced cable body to a pull string or fish tape. However, the tensile strength of our Kevlar-reinforced core prevents stretching during long pulls.
- Reattach at Terminals: After pulling the cable through the wall and conduit, reattach both heads at the ends. The vibration-proof stable connection will ensure the 48Gbps bandwidth of HDMI 2.1: a bayonet or screw-lock mechanism is preferred.
Step 3: Termination & Signal Validation
Once you have the cable set up and heads attached, tie in the source and display. The connector has an integrated signal indicator LED to give fast visual feedback on power and a completed handshake. Before closing up walls, this is a vital troubleshooting step. To achieve a neat look, combine the cable with a quality HDMI wall plate or keystone jack to provide an easily accessible, fixed HDMI port.
90-Degree In-Wall HDMI Cable Installation
This version of a 90-degree In-Wall HDMI Cable is best suited for low-clearance situations where the display mounts flush against the wall. The installation process is exactly the same; it just has to be properly oriented during planning (left or right) so that, when plugged in to charge, nothing forces it into a port by attempting to plug it in the wrong way. This design is ideal for recessed wall mounts and ultra-slim TV installations.
Why Does This Method Beat Traditional HDMI Extenders
For pure HDMI signal distribution, a direct in-wall HDMI 2.1 Cable is much better than using those low-cost, off-the-shelf bundles (HDMI over CAT6 extender kits). It is a plug-and-play, single-cable solution that natively supports all HDMI 2.1 features, including eARC for lossless Dolby Atmos audio and QMS for seamless frame-rate switching without compression, configuration, or any other baluns. This minimizes points of failure and ensures performance.
