DeX with 2 Monitors ?

Don't think DeX supports multimonitors...

I don't think DeX will support two monitors either. I thinking of getting an HDMI dual-connector to check though ..... At least I am able to connect my 32-inch monitor to DeX, which is good. My eyesight is not so good anymore. I might upgrade to a 42-inch monitor next year .....
 
You could always get one of those wide monitors. Would be almost like having two regular monitors.
