The decoder has two output windows that can decode the same or different content simultaneously for both the SDI and DVI output (compatible with HDMI and VGA). All you need to do is drag the video source that you’ve added to the corresponding output window, and the decoding card starts decoding.
Note: One interface cannot correspond to the contents of two output windows, and if both SDI and HDMI are selected in one output window, it will output the same content.
