XPS 13 with Displaylink 3100 non working HDMI ports

[YvesTh]

I have a XPS13 since last year, wanted to make life easier and have at least 2 decent sizes screens.
So i purchased a displaylink 3100.
But oddly enough even though this device is suggested in the Dell XPS13 configuration it does not seem to be supported.

Through the HDMI ports i am not getting any working display.
Through the DP i do, but this only gives me one screen.

So i am curious since i have the latest version software and latest version BIOS.
I am still not getting it to work.
So is Dell making the wrong recommendations or am i just doing something wrong.

Is there anybody with a XPS13 who has managed to get the 2 HDMI ports to work?

Hello,

It is the same driver and physical chip from DisplayLink doing DP and HDMI in that box designed/manufactured by Dell.
Until two week ago when I started testing our brand new chip, I have been using the Dell D3100 with 2 1080p HDMI monitors. I don't have the XPS13, but that shouldn't matter as we test on XPS13 before releasing and so does Dell.

Would you please be able to provide the logs as described in my forum signature?
Also, what kind of resolution are you trying to get on the HDMI?

Thanks,
Alban

Hello,

Resolution is set at 1920x1080

According to Dell support the XP13 does not support the DL3100.
While their configurator suggest the DL3100 as a docking for this model.

Hello Yves,

Tech support... <sigh> Why would Dell make a dock that doesn't support their flagship laptops?! If it was a Thunderbolt dock, I'd agree, but it's a real USB dock which even works on an Android phone.

From the logs, I guess you have tried a few things so we'll first have to clean up a bit. The many reboots are unfortunately necessary because Windows can't modify these drivers whilst running. We have some changes around that in the new Windows 10.
Here are the steps I advise:

Disconnected the Dell D3100 and leave it disconnected until asked to connect it
Remove 8.0.422.0 from Add/Remove program
Reboot
Run our Cleaner 8.0.422.0 (https://dl.dropboxusercontent.com/u/25722869/DisplayLink/EndUserCleaner8.0.422.zip) and "Run as Administrator..." even if your user is an admin.
Run our Cleaner 8.0.422.0 and "Run as Administrator..." again as the beta cleaner has a bug currently being fixed.
Reboot
Install 7.9 M7 (http://www.displaylink.com/downloads/file?id=576)
Connect the Dell D3100 when asked.
Wait for the device drivers to be associated by Windows.
Reboot
Gather new logs with the Customer Support Tool so I can check everything is peachy.


Kind regards,
Alban

Yeah typical Dell.

This is the new log file after following the steps.

Thank you. I'm still missing the crucial debug files and I only have the machine details.
I don't know if it's because the DisplayLink Manager service is not running or because the customer support tool could not get the files.

1. Could you try to switch the "advanced logging on", reboot and regather the files?
If the files like DisplayLinkManager.*.log are not in the folder, then I'll explain how to gather them manually.

From what I can see, the host software is installed correctly and the USB device driver is also up and running (you can see from Device Manager).

2. How is the HP E241i monitor plugged in? I see it, but we don't have its identification details (https://en.wikipedia.org/wiki/Extended_Display_Identification_Data) in a file. If it's plugged in the graphics card, that's normal. If it's plugged on the DisplayLink it's not.

[YvesTh]

I'll run it again.

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

[YvesTh]

The new log file.

[AlbanRampon]

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.

[AlbanRampon]

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...

[YvesTh]

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

[AlbanRampon]

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.

[YvesTh]

I'll give that a try if a other brand monitors might change something.

I seem to have a similar issue with this dock. Question: have you tried plugging it into a USB 2.0 port?

For me, the USB 2.0 port works but the USB 3.0 doesn't detect the dock.
