are you using a 2nd monitor at all? i wasn't able to select 2560x1440 for my main monitor because i was using a 2nd monitor that had a max of 1920x1080 resolution. i had to create a custom 2560x1440 resolution for my second monitor (note: i still run 2nd monitor at 1920x1080) via nvidia control panel then I was able to select 2560x1440 in game on my main monitor.
