With the bidirectional HDMI switcher, you can comfortably switch between two HDMI sources, such as a game console, DVD, or Blu-ray player, on your display, whether it's a TV, monitor, or projector. Optionally, an HDMI source device can also be displayed simultaneously on two HDMI displays. This way, you avoid the hassle of unplugging cables and running an additional HDMI cable to the display. The bidirectional HDMI switch forwards an HDMI input signal to two HDMI output devices or alternatively two input signals to one output device. The HDMI splitter 2 In 1 Out supports 3D and resolutions up to 4K at 30 Hz and is HDCP compliant. With the push of a button, either output 1 or 2 can be selected as the output display. Convenient switching at the HDMI switch saves you from unplugging cables and protects the ports. It is suitable for connecting Blu-ray players, satellite/TV receivers, computers, tablets, and game consoles like PS4 or Xbox to TVs, monitors, or projectors. The operation of the HDMI switch box 2x1 is done without external power supply directly via the connected HDMI device. Note: The HDMI switch does not function as a splitter.
