Problem of Asus universal USB docking station
 

I have an Asus computer: UX21E(Windows 7 Home Premium SP1..)
And I use the Asus dock station(Asus Universal USB Docking Station(I have instaled last software: DisplayLink 7.0M3)

I have one problem:
My computer is connected to the monitor via HDMI
Then there is connected via USB dock station - via the VGA is connected to the TV.
And always when I turn on the computer. I have a monitor connected via HDMI is black - and while I will not turn on the TV.

Is it possible to put the settings: turn off the video output dock station?
