The Ugreen Bi-Directional HDMI Splitter can be used to split an HDMI signal to two monitors or to switch between two HDMI sources on a single monitor. It can be connected either in 1-input, 2-outputs mode or in 2-inputs, 1-output mode. When 2 output devices are connected, the display will show on only one display at a time and can be toggled to the other display as required.
