External Monitors via DP not detected (Ultra Dock 90W, T470)

2017-11-22, 9:21 AM

Hi there,

I've got a new T470 and Ultra Dock and try to connect my 2 external monitors via DisplayPort but nothing happens.

I tried to update the firmware of the Ultra Dock but it won't work because I got the following error message in den update.log: "Error description: Can't connect to Synaptics VMMxxxx DP hub IC"

The 2 monitors were still connected to the Ultra Dock.

 

So I connected one of those monitors vie HDMI and installed the Firmware again. Now I got the current version 2.33.000 installed. But as soon as I remove the HDMI cable nothing happens again.

 

What else can I do? Do I have an issue with my Ultra Dock?

Solved! See the solution

Okay, nevermind. That was silly from me.

I had to switch the source port on my monitors. They were only searching on the HDMI port for signals. As I switched to Display Port everything worked fine.
