Thinkpad T410 + Mini Dock Series 3 - No screen on external display

Hello guys, I am running out of ideas. Maybe you can give me some much needed advice.

Today my bought a Docking Station (Mini Dock Series 3) for my Thinkpad T410. So when I dock my Laptop, he just gives me a black screen on my external display.

So i run xrandr:

Screen 0: minimum 8 x 8, current 2880 x 933, maximum 32767 x 32767
LVDS1 connected primary 1440x900+0+0 (normal left inverted right x axis y axis) 303mm x 189mm
   1440x900      60.04*+  50.00  
   1280x800      60.00  
   1024x768      60.00  
   800x600       60.32    56.25  
   720x450       60.00  
   640x480       59.94  
HDMI3 connected 1440x900+1440+33 (normal left inverted right x axis y axis) 521mm x 293mm
   1920x1080     60.00 +  50.00    59.94  
   1600x1200     60.00  
   1680x1050     59.88  
   1280x1024     60.02  
   1440x900      59.90* 
   1280x960      60.00  
   1280x800      59.91  
   1280x720      60.00    50.00    59.94  
   1024x768      60.00  
   800x600       60.32    56.25  
   720x576       50.00  
   720x480       60.00    59.94  
   640x480       60.00    59.94  

So it looks like, the display is recognized by the system. But there is just a black screen.
Changing the display output manually with Xrandr as described in Xrandr or Multihead didn't work for me either.

I am using an Intel Grafik card

00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)

If I connect the external monitor directly to my laptop, it works.

Just tell me if I missed to give you some important information

Thanks in advance.

I'm not sure if it'll help, but this page has some advice about using docks for thinkpads.
