With the 2-port HDMI splitter, it is possible to transfer your 4K image resolution to multiple devices with a single HDMI input. This allows you to enjoy two images simultaneously without effort. Plug & Play! The function of this HDMI splitter is that you can use the input from an HDMI or Micro USB cable to make two HDMI cables work. This is because a switch is made internally in our splitter to accommodate two HDMI cables, allowing you to play the same image on two different HDMI screens. So enjoy two screens simultaneously from now on! Please note: this switch is not intended to duplicate two screens. Use a splitter for this purpose!
