SPLAT Window size on Launch issue?

So I got a new monitor and it is 3840 X 2160 by default. Looks great. But, when I launch Splat the project window is small, as in the same size as it was with my 1920x1080 monitor. 
So I figured, OK, I will stretch the window to the size I want (just like in Windows) and it should launch like that nest time. Nope, it doesn't.
Is there a setting somewhere  to fix this . It gets real old having to stretch the windows everytime I open a project.
 
Maybe in the config file somewhere? I don't wnat to go there without some confirmation yay or nay.
 
Don't mind with fx and vsts, but the project window should stay?
