MSRP $999.00


This 4K multi-view switcher is a great fit for anyone looking to seamlessly flow between presentations and videos on one display, as well as simultaneously view up to four video sources on that display via a single HDMI output. Video sources shown either in full screen or through multi-view windows can be easily swapped with the push of a button from the IR remote and several other helpful control options to monitor multiple video sources at once.

Thanks to its [email protected] Hz resolution, every detail is captured from each video source. Two audio outputs also support audio de-embedding to extract audio from your sessions. Audio embedding options are also available via two inputs on the device.

Connectivity & Control

Integrated auto video scaling for each of the four HDMI inputs ensures video signals from your devices are compatible with 4K displays. Audio embedding is supported with line and mix in dual audio input. Audio de-embedding is supported via the two TOSLINK and 3.5mm outputs.

The BG-UMV-HA41 has several control options, including buttons on the front panel, IR remote control, RS232, and a web interface. The layout and size of each display window can be customized, and users can also choose from 16 preset layouts via the BG-UMV-HA41’s web interface. On the IR remote, there are four presets with four additional slots open for users to set their own presets.

The BG-UMV-HA41 can be easily rack mounted, furthering its flexibility for use in any environment.
