No errors...But display is blank

[eightman8]

I have this issue with a usb monitor (and Dynadock 3.0).
I believe the problem is the same. I'll just make my concern about the monitor.
I have been able to test the monitor on other systems.

My test subjects -
Sony laptop / Windows 7 / 64bit - Works perfect
Asus tablet / Windows 8 / 64bit - Works perfect
*Asus laptop / Windows 8 / 64bit - Problem!

The problem is that the monitor has power but does not show an image.
Computer reports no errors. The computer recognizes it and it shows up as an additional monitor in display control panel.
The cursor evens goes off screen as if it's on the monitor.

Here are the differences between the two Asus computers.
Laptop only has Usb 3.0. Also their are two display adapters on the Laptop
Intel HD 4000, Nvidia GT 650M.

I have installed and reinstalled, a few time, all the most recent drivers for both the display adapters and the displaylink.

Tired. Please Help. Any advice would be greatly appreciated.
