Frequently Asked Questions (Q&A)

Q: Can this extend to 4 different screens?

No, it can not extend to 4 different screens. All splitter outputs will always have the same screens

Q: Why the audio extract not working?

Make sure HDMI output 4 is connected to a display, or else the audio extraction feature will not work. Audio extraction only works when HDMI output 4 is connected to a display
