Keep DVI-D content visible where the source cannot be placed. The Black Box AVX-DVI-TP-100M extends digital video with audio and RS232 control, making it a practical fit for conference rooms, control spaces, digital signage, and other installations that depend on stable remote display delivery. HDCP support helps maintain compatibility with protected content, while RS232 pass-through preserves control signaling for integrated AV workflows. That combination matters in real deployments: you are not just moving video, you are preserving the behavior of the entire system. For integrators and infrastructure teams, this type of extender reduces the need to relocate source equipment into the display area and helps keep rack-mounted gear centralized. It is a cleaner architecture for rooms where cable distance, equipment access, and signal integrity all affect uptime and serviceability. Choose this model when the installation calls for more than basic video extension. It is designed for environments where audio, control, and protected content all need to arrive together, consistently, and without compromise.
