Keep four HDMI sources ready on one display input and change between them from the desk or across the room. The Eaton Tripp Lite Series B119-004-UHD is built for environments where multiple devices need to share a single monitor, projector, or TV without constant cable swaps. With support for 4K video, this switch is suited for presentation spaces, signage deployments, and AV workstations that need clear signal handling from modern source devices. Connect a Blu-ray player, game console, computer, or cable/satellite DVR, then select the active source as needed. That makes it easier to manage shared displays in conference rooms, classrooms, and control points where uptime and simplicity matter. The remote control adds convenience for installations where the switch may be mounted out of reach or placed near the display. For teams standardizing on a clean, low-friction AV setup, this model offers the right balance of source flexibility, display consolidation, and operational control.
