X1 Carbon Dual Monitors - max resolution not detected

[kvietmeier]

Setup:
Belkin Dual Display USB 3.0 Dock
X1 Carbon
Windows 8.1
Displaylink Mgr - 7.5.52874.0

Question:
Is there a limitation on screen resolution when using 2 monitors?

When my ASUS PB278 27" IPS monitor is the only display connected through the Display port I can drive it at the max 2560x1440 resolution of the display. However, as soon as I connect my Acer X223W to the DVI port the Displaylink drivers reset the ASUS to 1920x1080. Kind of a bummer, I'd really like to use both of these monitors if I can and I'm hoping this is a configuration issue, or maybe there is another dock out there that supports this.
