XPS 13 with Displaylink 3100 non working HDMI ports

I'll run it again.

Both monitors are the same.
The one thats actually working is plugged into the Displayport.

Thank you. Still missing the files... Frustrating!

Do you know how to stop a service and zip files?
If so, please STOP the DisplayLink Manager service.
Then go to C:\Program Files\DisplayLink Core Software\Debug and collect all the files.
If you don't, I can explain!

I don't know why we don't get any file with the tool.

[YvesTh]

Debug file zipped.

Not sure why the tool is not adding all files.

Thank you Yves.
There is no monitor detected, at all, by the chip in the dock.
For the DisplayPort monitor, I do see "hotplug" detection, then the monitor EDID being read and saved in the .edid file. However, there is nothing for any other head. That leads me to believe there is a fault in the hotplug detection hardware: no monitor is detected as getting plugged in, so the dock doesn't even try to read what's connected.
Is it a single dock behaving like that? If so, once you have verified it is not a cable fault, I would recommend contacting the manufacturer, Dell, to discuss a replacement. I suggest you copy this message so they don't waste time looking at the driver...

I purchased a 2nd DL3100 to test it wasn't a faulty unit.
But the new one did the exact same thing.

Have you tried with another monitor or HDMI cable?

I don't expect you to have a different behaviour on any other computer as the firmware does not see any monitor.
