You'll need not only 10bit monitor, but also professional video card, like nVidia Quadro or AMD FireGL.
Software drivers for consumer cards do not support 10bit color.

I believe it's a Poison Ocellate Octopus, Amphioctopus siamensis.  Looks like it's doing it's very best to warn you that it is Poisonous too

Thank you!

It was doing this not for me - it was hunting something, when it saw me it almost immediately retreated back to Cola bottle

I had the Subal DP-FE4 8" Dome w/ the Schneider diopter
and the 76mm Port Extension that was recommended and
the 16-35II. Had bad enough results that I quit using the
lens underwater and only shot my FE for W/A.

I'm using Subal FE4 with 16-35 without diopter lens, and I'm happy with it.
In 16-19 range the picture is very sharp in the center, but a little bit soft at corners, same at top-side.
In 20-35 range corners are ok.

I'm also very happy with autofocus performance thanks to 2.8. Had a chance to compare it this year at Cocos island: my friend with the same camera 5D2, but 17-40 lens had a lot of trouble focusing at 35m on hammerheads with clouded weather at the top. For me it was very simple, no trouble at all.
