3d video support Dell Dock - Pro Venue 11 7130

Hi,

I have a Dell Docking Station for my Pro Venue 11 (model 7130). Can the hdmi output signal be used for 3d video format, or do I have to use my mini Hdmi port on my tablet. 

I tried to play a 3d video blu ray with my tablet and my 3dtv but the software can't find my tv (hdmi 1.4 enabled tv). I was wondering if this has to do something with my Docking station. 

Thanks,

Benny
