TL;DR
A tech enthusiast has assembled a long-distance gaming setup using a 50-foot fiber optic HDMI cable, a Steam Controller 2, and custom Linux software. This DIY solution offers a near-console experience from a PC, bypassing Valve’s Steam Deck. The setup highlights innovative ways to enhance couch gaming with existing hardware.
A PC enthusiast has built a custom couch-gaming setup using a 50-foot fiber optic HDMI cable and Steam Controller 2, offering a DIY alternative to Valve’s Steam Deck. The setup allows seamless switching between work and gaming modes, with the long cable and new controller enabling a near-console experience from a distance. This development underscores innovative approaches to enhancing home gaming setups without purchasing dedicated consoles.
Matthew Brunelle, a dedicated hardware enthusiast, has created a unique gaming configuration that connects his PC to his living room TV via a 50-foot fiber optic HDMI 2.1 cable. This cable, costing approximately $75, transmits high-bandwidth signals over long distances without degradation or latency, enabling a smooth gaming experience on his TCL Roku TV. Brunelle also installed Bazzite, a Linux-based OS, on a third SSD, which automatically handles display and sound outputs, simplifying the process of switching between desktop and gaming modes.
Complementing this setup is the Steam Controller 2, which Brunelle finds more reliable and comfortable than the DualSense, with improved connection stability. The controller pairs seamlessly with Steam and Linux, allowing him to control games from the couch while the PC remains in his room. Brunelle boots into Bazzite for gaming, which automatically outputs to the TV, and uses standard boot procedures to switch back to his NixOS desktop environment for work. He is also experimenting with hibernate-to-disk features to further streamline the transition between modes.
Brunelle’s setup demonstrates how existing hardware, combined with custom software and high-quality cables, can replicate the experience of a dedicated gaming console, sidestepping the need to buy Valve’s Steam Deck or similar devices. While still requiring manual steps for switching between modes, Brunelle reports that the process is becoming increasingly seamless, with plans to improve hibernate support for even smoother transitions.
Implications for Home Gaming Enthusiasts
This setup illustrates how dedicated PC users can create a cost-effective, high-quality couch gaming environment without investing in proprietary consoles. The use of fiber optic HDMI cables and reliable controllers demonstrates that enthusiasts can customize their setups to match or surpass commercial solutions, especially as hardware and software improve. It also highlights the potential for Linux-based OSes like Bazzite to simplify multi-display and multi-mode configurations, making PC gaming more accessible from living rooms.
Such innovations could influence future hardware designs and software tools aimed at home entertainment, encouraging more DIY solutions that leverage existing PC components for a console-like experience. For the broader gaming community, this underscores a trend toward personalized, modular setups that prioritize flexibility and performance over off-the-shelf solutions.

Long-Distance Gaming and DIY Innovations
Recent years have seen increased interest in extending gaming setups beyond traditional desk environments, driven by the desire for more comfortable, living-room-friendly experiences. While wireless streaming solutions like Steam Remote Play or Moonlight are common, they come with latency and bandwidth limitations. Brunelle’s approach uses a fiber optic HDMI cable to avoid these issues, enabling high-fidelity, low-latency video transmission over a long distance.
Historically, long HDMI cables suffered from signal degradation, but advances in fiber optic technology and HDMI 2.1 standards now allow for reliable, high-bandwidth connections. Enthusiasts have experimented with custom cables and software solutions to bridge the gap between PC and living room TV, but Brunelle’s setup is notable for integrating hardware, software, and a new controller for a near-seamless experience.
Valve’s Steam Deck and other portable gaming devices have aimed to bring PC gaming to the couch, but Brunelle’s DIY solution shows that dedicated enthusiasts can achieve similar or better results with existing hardware and some ingenuity, emphasizing the importance of customization in the gaming community.
“Brunelle’s setup demonstrates that with the right combination of hardware and software, a DIY long-distance gaming station can rival commercial solutions.”

Remaining Challenges and Limitations of the Setup
It is not yet clear how well this setup will scale or perform over extended use, especially with different hardware configurations or higher refresh rate displays like the upcoming LG C5 OLED. Brunelle is experimenting with hibernate-to-disk features to improve transition times, but full automation and zero-manual intervention remain unconfirmed. Additionally, long-term reliability of fiber optic HDMI cables in daily use has not been widely tested.
Further, the latency introduced by software and hardware switching, as well as potential issues with compatibility on Linux, are still being evaluated. The setup’s dependence on manual booting and configuration steps may limit its practicality for everyday gaming for some users.
