Default Info

Perhaps it would be better to ask for the contents of the resulting zip file from the Support Tool? Anyway, here is what I got within reason.


1. Windows 10 Build Number
Microsoft Surface Book
OS: Microsoft Windows 10 Pro (x64-based PC), No Service Pack, English
OS Build: 10.0.14393.0 (Debug = False)
OS Build Label: 14393.rs1_release.161220-1747

2. Enumerate each display, its resolution and if it is connected to the graphics card or a USB adapter:

Both monitors are 1920 x 1200 and using USB adapter to Surface Book.
VS24A Manufacturer: ACI ProductCode: 24D1 Serial: F9LMQS066306 Built: 38/2015
ASUS VW266H Manufacturer: ACI ProductCode: 26A4 Serial: 96LMTF180980 Built: 27/2009

3. The CPU ***full*** name including the numbers after iX (available from System_Details.txt as well). Generation is more important to understand the architecture rather than if it is an i3 or i7.

CPU: Intel(R) Core(TM) i5-6300U CPU @ 2.40GHz
Number of Cores: 4
Might be Skylake?


4. The GPU details (available from System_Details.txt as well).


Graphics: NVIDIA GeForce GPU (NVIDIA)
Graphics Driver: 21.21.13.6961 Dated 2016/10/20
Graphics: Intel(R) HD Graphics 520 (Intel Corporation)
Graphics Driver: 20.19.15.4463 Dated 2016/07/06
Graphics: DisplayLink USB Device (DisplayLink)
Graphics Driver: 8.1.843.0 Dated 2016/12/01
Graphics: DisplayLink USB Device (DisplayLink)
Graphics Driver: 8.1.843.0 Dated 2016/12/01
WEI Base Score is 6.4, CPU 7.5, RAM 8.2, GPU 6.4, Gaming 9.9, Disk 8.8

5. What you include in your CPU usage (which processes: overall, WUDF, DWM...). Note: I really need WUDF more than the rest as DWM is a Windows process).
Not sure precisely what you mean - but the top 5 when at-rest are:
WDF
Task Mgr
Windows Explorer
DWM
Chrome

6. The value of CPU being used.
Not sure what you mean here - typical CPU usage details are below.

7. What happens on ALL indirect displays (indirect = through USB). If you have Task Manager on an indirect display, then it is NOT idling as content changes!!! This is really one of the most important point. Here are some examples:

7a. Content fully static: nothing changes at all, and I mean nothing, not the clock, not the mouse pointer.
Ehhh - how do you want me to capture CPU % without anything open? Run a CPU logger? Is that of any value? I suspect WDF would be less than 2% and total CPU is around 8%

7b. Some little area changes: like for instance you only have some numbers on the clock or the numbers in Task Manager.
WDF anywhere from .5% - 2%
Total CPU is around 8%

7c. Only the mouse pointer across indirect displays. (if you do this, please do NOT use the mouse trail accessibility feature or this is the same use case as 7b).
WDF 28% - 30%
Total CPU is about 60% as other extraneous processes start to take up a little more CPU when I move the mouse.

7d. Moving a window. Indicate an idea of the size of the window... I mean moving a 10x10 pixels windows is obviously fundamentally different to moving a 4kx4k one.
A full-size-ish window (not maximized but filling a 1920 x 1200 display)
WDF – 30% - 38%

7e. Playing video on VLC
Video maximized on one screen.
WDF about 30%
VLC about 15%
DWM about 5%

7f. Playing video on a browser (and the value is constant across browsers). Our driver CANNOT differentiate which browser is playing.

With YouTube maximized on one of the screens (task manager on the other)
Total CPU = 100%
WDF 38%
Chrome 28%
Chrome 22%
DWM 3%
Task manager 2%



7g. Game, full screen or windowed? Games do NOT use the same as video playback
.
Haven’t tried playing games (I don’t actually have any installed), I’m sure it would be catastrophic.

8. Which version of DisplayLink driver you are running as, like Windows builds, they don't all have the same features. (available from System_Details.txt as well).

DisplayLink Version: 8.1.843.0
DisplayLink Installer Source: Normal or WU installed
DisplayLink Audio Version: 1.54.0.0 (DisplayLink USB Audio 2.0 Class Driver)
DisplayLink Ethernet Version: 2.34.17.0 (DisplayLink USB CDC NCM Driver)
No DL USB I/O drivers found.s
DisplayLink RS Version:8.1.843.0 (DisplayLink Core Software v8.1.843.0)

This is my work setup below. I take the laptop home where I have the same dock, but different monitor setup. There I have one monitor connected via the laptops built in miniDP port to DP on the monitor, then two others via HDMI on the dock (laptop lid is closed, so screen is not in use). Incidentally I have to use the miniDP on the laptop as the DP port on the dock refuses to work. The monitor just flickers between no signal and powered off (another non-displaylink dock with a different laptop works fine with DP).

Happy to try beta/alpha builds. I work in software and beta test for other companies, so know how to provide decent feedback etc.

1. Windows 10 Build Number
Computer: Dell Inc. - XPS 13 9343 4Q5GT32
OS: Microsoft Windows 10 Pro (x64-based PC), No Service Pack, English
OS Build: 10.0.14393.0 (Debug = False)
OS Build Label: 14393.rs1_release.161220-1747

2. Enumerate each display, its resolution and if it is connected to the graphics card or a USB adapter
Primary Resolution: 1920x1080x32
Desktop Size: 5760x1080
Number of Monitors Connected: 3
Monitors Connected:
Manufacturer: SHP ProductCode: 1420 Serial: 0 Built: 2/2015
S240HL Manufacturer: ACR ProductCode: 0289 Serial: LU5EE0018536 Built: 46/2015
S240HL Manufacturer: ACR ProductCode: 0289 Serial: LU5EE0018536 Built: 46/2015
In english: one laptop screen and two Acer S240HL 1080p screens both connected via Dell D3100 dock on HDMI.

3. The CPU ***full*** name
Intel(R) Core(TM) i5-5200U CPU @ 2.20GHz

4. The GPU details
Intel(R) HD Graphics 5500

5. What you include in your CPU usage
With no activity on the indirect displays, WDF is < 1% (average of 0.5%). Activity causes CPU to increase. I can get it to 100% with a youtube video playing on each connected display,with WDUF competing with Chrome for CPU.

6. The value of CPU being used.
By WDF? Anywhere from 0.5% to 30% depending on activity

7. What happens on ALL indirect display
7a. Content fully static
WDF - 0.5%

7b. Some little area changes:
WDF - averages around 1-2%

7c. Only the mouse pointer across indirect displays
WDF - 1.5% on build in screen, 20% on indirect displays

7d. Moving a window
Dragging full 1080p Outlook window around
WDF - 1% on build in screen, 25% on indirect displays

7e. Playing video on VLC
Don't have VLC

7f. Playing video on a browser
WDF - 2% if browser is on built in screen - 30% if either of the connected displays

7g. Game, full screen or windowed?
I don't play games - it's a work PC

8. Which version of DisplayLink driver you are running as
DisplayLink Version: 8.1.843.0
DisplayLink Installer Source: Normal or WU installed
DisplayLink Audio Version: 1.54.0.0 (DisplayLink USB Audio 2.0 Class Driver)
DisplayLink Ethernet Version: 2.34.17.0 (DisplayLink USB CDC NCM Driver)
No DL USB I/O drivers found.
DisplayLink RS Version:8.1.843.0 (DisplayLink Core Software v8.1.843.0)

I had posted a ton of details on here yesterday and now it is deleted. Why? That took a lot of time and research to help you all out and hopefully fix the problem? I found that the CPU being eaten up was due to the driver calling a directx 11 DLL as well as provided the numbered list requested. Did I violate some kind of TOS?

Nothing is getting deleted. Like many, many but many forums, posts with attachments are moderated. The number of spam/porn/fake medicine messages that don't invade your inbox because of this measure is relatively high.

So why was it removed? It wasn't spam, it was all technical detail on this problem.

You removed it from public view pending review when you added attachments.

Thanks for clearing it up, I had thought I did something wrong, and only want to help.

This issue makes using the dock for Skype meetings or Webex impossible. I have to log into my VDI through my windows Phone and Continuum dock to join any meetings that have presentations or undock my laptop.

Default Workaround until driver update

I have been fighting with my workstation for several weeks with resource issues. Locking up, running out of memory, cpu running way with resources, fan that sounds like a jet engine, etc...

After a lot of research I stumbled upon this post as I was looking at Windows processes and Endpoint protection as the cause of the issues. However I have now unplugged my dock, uninstalled the current DisplayLink driver issued on December 18 and rebooted my machine. On reboot I inserted the dock USB into a different port and let it install the driver through Windows. I am happy to report that my machine has returned back to normal...so far...

Running Windows 10 Anniversary. After letting windows install the driver the display adapter appears as "USB3.0 Dual Video Dock" Driver Provider: DisplayLink Driver Date: 8/17/2016 Driver Version: 8.0.762.0 Along with the display adapter I have "USB Giga-Ethernet" Driver Provider: DisplayLink Driver Date: 5/20/2016 Driver Version: 8.0.403.0

Fingers are crossed but it appears to have solved my issue!

Hello,

Would you please be able to share your CPU+GPU details?
Also what kind of resolution are you external displays?
If I can understand the CPU issue, I don't get the high memory usage...



As a general update, I have created support tickets with details from the different posters here in preparation to share a development build to test. However, during tests, an unrelated issue was found so I have not yet shared anything as I am not satisfied with the quality.


Kind regards,
Alban

Nice to see you are having some success. I just went through the steps you outlined here, and my problem persists. Just moving the mouse on the screen causes WUDFHost to still jump from 4-25% CPU.

It took a while for windows to recognize the display adapters, but my keyboard and mouse it had no issue with.
