2560x1440 while listed in the manual has the suffix RB on it.
RB appears to be "Reduced Blank" and even I can't guess if your card supports that. I'd try 1080p next.

I just bought a SAMSUNG U28D590DS and have put the resolution on 2560x1440 because my pc can't handle the 4k settings. When i watch video's on the internet while using a player like Youtube or Netflix. I get this thin white line on the right edge of my screen. It does not show this white line when i use a player thats on my pc like: Windows media player, VLC media player and KMplayer. I neither have the line when i put my resolution up to 4k (3840x2160). So when my screen is on 4k is never see the white line neither on Internet players. But on the lower resolution it does. I dont understand why it does this. Can you guys help me out. Hope the hear some good news.
