Hoping someone can help me with my situation. I have two Asus PB287Q monitors connected to my GTX 680 desktop.

One is connected via a dual-link dvi port and getting the 2560x1440 resolution by default. The other is using a HDMI 1.4 supported cable but only gets 1920x1080 resolution.
I know that it can support 2560x1440 as my Windows 7 install picks up the resolution at 60Hz no problem over the HDMI.

How I can fix this?

Current install setup:

Dual boot ubuntu 14.04/Windows 7   
Latest Nvidia drivers

Welcome to Ask Ubuntu! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – guntbert Apr 20 '14 at 9:51
