Users can easily switch between displays using mouse and keyboard hot keys. Front panel buttons on the switcher are also available, as well as an IR remote controller. With the two USB 2.0 device ports, up to four computers can share the same printer, camera, or other peripherals. An audio push button is also available that allows users to select the audio from the BG-MKVM41R’s HDMI input sources while using quad-view.
