HUD scaled up on widescreen

Running i7, gtx1080ti, 16gb, 5760x1080 (spanned across 3 monitors).

Everything installed and loaded correctly, and game, so far, seems to run smoothly at 5760x1080.

Problem is, the HUD menus are scaled way up, so that most options are cut off.

Can't even make it through training, as most checkboxes needed for progression are below the cut-off.

Tweaked settings, but no change.

Bug?
