Simply press the button on the HDMI box to make a shift of the input or output source. With 3 LED indicators, you can easily know which connected HDMI device is running.If you want to play 8K video or images, you need the input source device, input, and output HDMI cable, output display all to support 8K, and not a single one can be omitted.If the HDMI cable or display device does not support 8K, the possible failure phenomena are: no signal, display device black screen, screen flicker, screen snow, screen discoloration (red screen, green screen), screen streaks, have video but no audio and other undesirable conditions. If the resolution of the input signal source is reduced to normal display, it can be judged that one of them does not support 8K.
