Atomos Ninja V - Ups, No Anamorphic 50P 4:3 FULL screen monitoring?

Hi Guys, hereby a short non-scientific test, I cannot get the Atomos Ninja V to work in full-screen 50P 4:3... Really? Your help is highly appreciated, please post your experiences underneath, let me know if you have any questions! (I know, I did not really explain this properly, bare with me it was a long day! :) @4:20 This is the mode in 25P that shows full screen, this is the way 50/60P should work, but no luck, it scales down.
