F48v4 Test Overlap

Hi folks, i have a bit of a strange one and i'm hoping someone can help.

I have a F48v4-NS set up with a differential receiver cards. I have a load of pixel tape connected to several of the outputs.

When I run each of the outputs in teat mode individually everything responds (mostly) as expected, when i run all outputs at once some of the pixels seem to cancel each other out and I get spots with no pixels lit up.

On a few of the outputs, when I turn on a single output, part of that run of pixel tape lights up but so does a chunk of tape on a completely separate output. 

I have checked for overlaps in dmx addresses and none exist. The controller exhibits the same behaviour when driven by Artnet, i'm not quite sure whats going on.

Does anyone have any bright ideas?

Don't get too hung up on the built in test function.  They don't always work as expected, especially with a newer controller.  If you really want a more valid test, use FPP's test function which will also confirm your player and controller setup and configuration.
