You sure the false color isn't on?
I thought maybe it was that but monitor on camera seemed good and not on false color.
Hum. Interesting! Decimator on aura photography mode .
First be sure the issue comes from the decimator. Try changing the input source to another camera if the problem persists, try another monitor. Also you might want to switch to another power source but I highly doubt it’s a power issue.
If the problem goes away when you changed the camera it might be a termination issue.
I thought I might have been seeing the same issue on a c300 the day before. But not certain. Just had the c300 output SD that day.
The wireless video signal was the same image.
I don't have any other cameras to test it on but I will as soon as I get the chance.
