Introduction :
The HDMI matrix 2x4 can connect 2 HD signal sources to 4 HD display terminals
with optical fiber or stereo headphone output. The matrix allows two HDMI devices to be switched or split easily to four HDMI compatible monitors or projectors. And any output ports can realize independent audio output by optical fiber or stereo head phone.（The audio can only be separated from the input of HDMI OUT1）

- Picture flash or freeze: change better quality and shorter HDMI cables
- Not support the highest audio format you want: check if two or more simultaneous outputs support
- HDMI output does not support HDMI ARC port on sound bar
