Default Also happens with multiple documents in Word - 6 external screens

1. Windows 10 Build Number
OS: Microsoft Windows 10 Home (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:

Manufacturer: AUO ProductCode: 139E Serial: 0 Built: 1/2009 - 1600x900 - AMD Radeon 6600M
ACER V243HQ Manufacturer: ACR ProductCode: 00B0 Serial: LG8080074221 Built: 20/2011 -1920x1080 -USB\\VID_17E9&PID_0360
ACER V243HQ Manufacturer: ACR ProductCode: 00B0 Serial: LG8080074221 Built: 20/2011 -1920x1080 -USB\\VID_17E9&PID_0360
ACER V243HQ Manufacturer: ACR ProductCode: 00B0 Serial: LG8080074221 Built: 19/2011 -1920x1080 -USB\\VID_17E9&PID_0360
ACER V243HQ Manufacturer: ACR ProductCode: 00B0 Serial: LG8080074221 Built: 20/2011 -1920x1080 -USB\\VID_17E9&PID_0360
ACER V243HQ Manufacturer: ACR ProductCode: 00B0 Serial: LG8080074221 Built: 20/2011 -1920x1080 -USB\\VID_17E9&PID_0360
ACER V243HQ Manufacturer: ACR ProductCode: 00B0 Serial: LG8080074221 Built: 20/2011 -1920x1080 -USB\\VID_17E9&PID_0360

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) i7-2630QM CPU @ 2.00GHz
Number of Cores: 8


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

Graphics: AMD Radeon 6600M and 6700M Series (Advanced Micro Devices, Inc.)
Graphics Driver: 15.201.1151.1008 Dated 2015/11/04
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
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
Graphics: DisplayLink USB Device (DisplayLink)

Graphics: DisplayLink USB Device (DisplayLink)
Graphics Driver: 8.1.843.0 Dated 2016/12/01
WEI Base Score is 4.5, CPU 7.4, RAM 7.4, GPU 4.5, Gaming 6.1, Disk 7.9


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).

6. The value of CPU being used.
Total CPU
Total % but when I look at the resource monitor it is spread across all 8 cores
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.
With 3 x USB\\VID_17E9&PID_0360 connected 5%
With 6 x USB\\VID_17E9&PID_0360 connected fluctuates 12%
7b. Some little area changes: like for instance you only have some numbers on the clock or the numbers in Task Manager.
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).
With 3 x USB\\VID_17E9&PID_0360 connected fluctuates from 30-50% with 6 Word documents open on these screens
With 6 x USB\\VID_17E9&PID_0360 connected fluctuates from 30-70% with 6 Word documents open on these screens

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.
With 3 x USB\\VID_17E9&PID_0360 connected fluctuates from 30-50% with 6 Word documents open on these screens
With 6 x USB\\VID_17E9&PID_0360 connected fluctuates from 30-100% with 6 Word documents open on these screens, mouse and keyboard stutter and Windows starts reporting USB device errors

WUDF is always the top of usage list. Screens are landscape with each document occupying have of one screen. ie 960x1080
7e. Playing video on VLC
Not tested.
7f. Playing video on a browser (and the value is constant across browsers). Our driver CANNOT differentiate which browser is playing.
Not Tested.
7g. Game, full screen or windowed? Games do NOT use the same as video playback.
No games.
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).
Graphics Driver: 8.1.843.0 Dated 2016/12/01

With 6 x USB\\VID_17E9&PID_0360 connected and the CPU above peaking across all threads when we resize, edit and copy/paste the CPU temp rises to over 90 degrees C and the CPU throttles and the documents drop back to the laptop. It is as though Windows has reset the USB port/s.

Current workaround is to use only 3 of the 6 x USB\\VID_17E9&PID_0360 until patch available. The 6 x USB\\VID_17E9&PID_0360 have worked well for years under Windows 7 and then Windows 10 and started misbehaving with the Windows Anniversary edition.
