No, sorry. I am not using that resolution, and I do not know what else you use with it. 

There are settings for "Window Formation Display", where you should edit the Formation X and Y offsets, so they stay inside the box. Also, would be good idea to increase the window Width, which would in turn decrease the "Transposition Select" window width (the window with the actor names).

Even then, cannot guarantee my formation scene would look good for you, maybe it indeed doesn't. But there are settings to change window proportions, and the X and Y offsets, so you should try them out.
