If so, it looks like the software is doing the right thing, and giving you 2 extended displays, but the hardware is faulty and not rendering out of the HDMI port.

Hi Wim, you have seen 3 screens in WDP because in the meantime I have also connected the second monitor via the external VGA connection of the laptop, so I do have 3 monitors, but only because I have gone through the external VGA connection of the laptop.
When I plug/unplug the HDMI connection, the system does not flash or move or do anything at all.
Maybe I do have a problem with the HDMI connection.
My monitors have various entries and the second display is connected both via VGA cable and HDMI cable. The VGA connection directly to the VGA external connector of the laptop works fine, but the HDMI connection via le docking station does not work at all.

In fact my interim solution is to connect one external monitor via the DVI connection of the docking station and another via the external VGA connection of the laptop with another VGA cable :-(
That means 2 cables and of course a docking station in USB2.0 for the other connectors (USB2 and USB 3 ports, Audio and Ethernet)

Any clue why that HDMI connection does not work?
Hardware issue?

Thanks for your help.

I'm starting to think its a hardware issue. HDMI Hotplug is used to signal to the software that there is a display connected. It sounds like this hotplug event is not getting sent to the PC, so no display is enabled.

My Kensington dock is working! In Windows 8! Good grief, it's working... full USB3 speed, dual monitors, gigabit ethernet, and everything works just as it's supposed to. Turns out it wasn't necessarily a problem with the Kensington dock at all. Rather, I'm blaming Microsoft's USB 3.0 drivers for this one. I have two laptops I'm testing with this dock. Neither one worked previously with it, but the fix is similar for both:

Sony VAIO VPCSC1AFM:

This laptop has a Sandy Bridge architecture, and in Device Manager the controller showed "Renesas USB 3.0 eXtensible Host Controller - 0096 (Microsoft)". I was able to download the non-Microsoft driver from Intel's web site here and install it (ignore the fact that it doesn't say "Windows 8" on that page - it works). Once I did and rebooted, the Kensington dock worked perfectly! Absolutely no problems so far. Easy.

Lenovo ThinkPad X1 Carbon:

This ultrabook uses a newer Ivy Bridge architecture, and so the Renesas driver won't work. Intel makes it difficult to install their driver in Windows 8, but it can be done by following these instructions on Plugable's site. Once I did that, the ThinkPad worked with the Kensington dock, too. Again, absolutely no problems so far.

It's a huge relief for me, and hopefully things will continue to work fine. Maybe this post will help someone else out, because the problem was driving me crazy for days trying to find a solution.

Thanks for the information. I am going to try it and let you know if it also works for me :-)

IT WORKS FINE for my ASUS Zenbook Prime UX31A also!!!
It now works in USB 3.0 as it was working in USB 2.0, after having replaced the Microsoft Drivers with the Intel Drviers for Windows 7!!!
Simply need to follow these instructions on Plugable's site as stated by beaveyOne.

Thanks for your help beaveyOne :-)

I still have my second display issue on the HDMI port, but I suppose that is a hardware issue on the Kensington docking station. I will have it changed and cross my fingers ;-)

[jjp]

AFter changing the docking station for a new one, I still have the issue with the HDMI port for the second display :-(
When I plugin the HDMI cable, nothing happens at all. None of the screens flash.
Like Wim says, it's like if the event of the connection of the HDMI cable does not launch any hotplug detection or anything and the screen is not seen by the system.
It is now no longer a hardware issue, as I changed the docking station station for a new one, but there is still no way to get the HDMI port working correctly :-(

Can someone be of any help at all??!!
Wim??!!
