Switch four HDMI inputs onto one HDMI display using this 4x1 UHD 4K HDMI Switcher from Comprehensive. The switcher supports input and output of up to UHD 4K60 video with up to 7.1-channel embedded audio for display from multiple sources such as a computer, Blu-ray, camera for display on a monitor, TV, switcher, recorder, live broadcast/stream, or digital signage. It fits right into your classroom, conference room, showroom, lecture hall, retail display, and wherever you need a display with multiple sources.

Video features include support for 3D video, 12-bit deep color, HDCP, EDID management, and ARC (audio return channel). It can input and pass through embedded PCM and Dolby digital audio, and you can de-embed the audio over the 3.5mm line output to a speaker system or mixer. For longer cable runs, the switcher also supports equalization and re-clocking so there's no delay or loss of signal.

The switcher can be controlled remotely by the included IR remote, and you can also control it via the RS-232 port with a separately available adapter and serial controller. A power supply is included as well as an IR receiver cable and an optical audio adapter for optional S/PDIF output.
