Ok I have tried with a powered hub and no go... I have swapped the monitors around and they both work fine through the Thunderbolt port but whatever monitor goes through the Displaylink adapter just does not work....
Basically the power button on the monitor changes from orange to blue when it is in use and this indeed does happen, the screen changes from pitch black to a very dark grey so there is some life. The second monitor shows up in preferences but it is just not showing the extend desktop...
It is very annoying can anyone shed some light? Please?
