Review on Switch - Splitter 1HDMI:2HDMI, 4K, 60Hz, 3D splitter by Nguyen Bach ᠌

The description says it's a "switch-splitter" but. - What is called a switch: when there is more than one state and you can choose between them. This device can - you can turn on 1 source and switch between two TVs. also in the opposite direction - 2 sources to one TV. - What is called a splitter: when you can split one stream into 2 identical ones, each of which will be identical to the original one. THIS DEVICE CANNOT. And at the same time, the description clearly says ". output the video signal to several devices at the same time." There is obviously no simultaneity here.
