This is because of the ANC Data tally. Which is a data protocol and not an onscreen border.. Like the Atem Camera fiber converters had.

Some HD B4 lenses will cover the 2K window, so yiu can use the 2K window and get 2K output to the SDI. The camera does not upscale the video signal from the windowed mode, so you can not get 4K output. This is a hardware limitation of the camera.
That said, you can upscale the Video in post production in some NLEs to get 4K from HD or the 2K file.

Well that it will not cover the full sensor with a B4 lens oke.. But internal upscale to be compatible with 12G output would make a nice addition. (And would be possible.. As the sdi port can also scale down from 4K to HD on it's output port. )
Why in the ... Would you want 12G output running a B4 lens?? Well Imaging you are running a 4K show with ursa's.. Most of them with a EF or PL lens running 4K without a problem.. But that 1 / 2 cameras on FOH.. Need a big box lens.. (66x/72x or bigger..) But because theAtem needs all sources to run the same Resolution and Framerate.. Now you are in trouble because your Crop mode will push you into 1080P from a camera standpoint.
So to match the Atem you will apply a Teranex AV between it just for the upscaling to match the Atem resolution..
And there we go.. Adding a few more frames on the FOH cameras because of the external conversion.
Internal conversion into 1080P or 3840P output will probabbly be way more faster...
