Default 2560x1440 on 4K monitor missing

I have a Dell D6000 which is based on Displaylink DL-6xxx. My monitor is Acer B286HK which is a 4K monitor. I have a Macbook running High Sierra 10.13.3 with Displaylink driver 4.0.0.85514.0.

When I connect the monitor using the D6000, it displays in 4K@60Hz without issue, but the fonts are too small. Ideally I would like it to be at 2560x1440 mode but when I go to System Preferences>Display>Alt-click Scaled, the next highest resolution from 4K is 2048x1152, there's no other choices in between.

I know the monitor can do 2560x1440 since if I connect the monitor directly to Thunderbold port, by passing Displaylink I can scale to that which is the optimal resolution I need. How do I get 2560x1440 to work with Displaylink?
