I've encountered a problem with my camera's SDI output.
There is a heavy green cast to the output. Occurs on multiple different monitors with both SDI 1 and SDI 2.
However, If I ask the mini to output Bars on the SDI the bars look perfect.
(Examples below - This is a white wall fyi)

Changing the output LUT doesn't have an effect.

I know my way around this camera, but I haven't fully discounted this being my own mistake. Thoughts?

I'm running 6.1.2

Sorry for the giant photo attachments.
I want to add, the cast is still the same when output is set to CLEAN.
And the image on the EVF and recorded in-camera is good with no cast.

Hey,

please check the "Look config" menu of the ALEXA Mini.
Maybe the EVF is set to ALEXA Classic 709 and the SDI to Look and the Look itself produces the green cast?!

Have you also tried an Auto White Balance? I think this does not help here as you already mentioned that it's not on the EVF but on SDI1/2. So maybe it worth to check the settings above.
