Troubleshooting

The output is black

Work outwards. Is the output live, not merely enabled? Does its canvas region overlap anything you actually mapped? Is the source producing frames? Substitute a test pattern — if the pattern appears, the problem is upstream of the mapping.

Content is offset by a few pixels

Almost always a canvas that does not match the wall. Re-measure the real pixel dimensions — including any gap between panels the processor is expecting you to account for — and correct the canvas rather than nudging the mapping.

Performance falls over on a large canvas

Very wide canvases with many mappings are GPU-bound. Reduce the number of overlapping mappings, close the preview while running live, and prefer Syphon to NDI where both are possible — NDI encoding costs real CPU.

NDI receivers cannot find the output

A discovery problem, not a video problem. See NDI output.
