if you have a 21:9 screen then there are no solutions (a priori there is an option to move the HUD but I don't know where)
My friend MrTheace85 has the same problem on his screen but as it's only at the end screen it doesn't bother him.
Friend of mine has a 32:9 monitor, he can't see the chat in the end-screen at all, and there isn't a fix for it. BF4 isnt made for aspect ratio's like that
