I cannot get this off Google or the manual.
At least, not without $80 more coffee and facepalming.

How the heck do you enable the 4k HDMI output? Mine is greyed out and despite all the combinations I run through, nothing enables it. The camera was new around Nov 2014.

Thanks!

It may be an EDID issue - have you set the record format on the recorder (I assume it is your new Shogun) first? 4k is new enough you may need to "force" the EDID handshake.
