Hi there - I have a VGP-PRZ20 docking station connected to my Z Series Vaio. All good so far. The problem is that if I try to connect the extra monitor that I use to the docking station via the Monitor Port, I don't get any picture. So, naturally, I have to connect the monitor directly to the laptop, which kind of defeats the purpose of having the docking station.

Any tips on how to fix this or am I doing something wrong? Unfortunately the monitor is a bit old so it doesn't have an HDMI port.

Thanks,

Gordon.
