Don't change the project settings if you intend to deliver 3840x2160. (I'm assuming 3440x2160 is a typo.) What are you trying to do and what is the ultimate delivery for this project?
3840 / 2160 = 1.78 (the 16x9 aspect ratio of UHD and HD), but 3440x1440 is 2.39 CinemaScope. That will scale in a 3440 container, and you can either letterbox it to 2.39 or set the vertical resolution to 1608, which will give you the correct 2.39 aspect ratio.
Aspect ratios, image scaling, and delivery formats are not a simple subject. If you're dealing with a specific distributor or channel, make sure you get all the specs from them in writing and follow them to the letter, so you can avoid any later technical issues.
