Bidirectional HDMI Signal Splitter ACTVH245 from Nimo
This device is an HDMI signal splitter, which can be used in both directions, both as HDMI input and output.
For example, we can use it as 2 HDMI inputs and 1 HDMI output to connect 2 devices like a DVD player and console to one HDMI output of a monitor.
Another example is to use it as 1 HDMI input and 2 HDMI outputs to connect a console or DVD player to 2 HDMI outputs of a monitor or TV (in this case only the signal will be displayed on the selected output 1 or 2).
Its box is metallic in black, it has a button to select the output and it is very small in size.
