Display blank and network resets
Since upgrading to W10 and this version of the driver, I've been seeing both of my external displays blanking and then coming back to life. Looking in the event log at about that time I am also seeing a network reset:

Event ID 10400, Source NDIS
The network interface "dynadock Ethernet" has begun resetting. There will be a momentary disruption in network connectivity while the hardware resets.
Reason: The network driver detected that its hardware has stopped responding to commands.
This network interface has reset 4 time(s) since it was last initialized.

System is Surface Pro 3, Toshiba DynaDock, with two external monitors. Internal monitor normally off. Also plugged into Dynadock are network, keyboard, mouse and headset.

Hello, I am facing exactly the same problem as Lloyd writes - from time to time (sometimes very often, each 2 minutes) it looks like DisplayLink stops working, whole laptop freezes (even embedded display, even mouse cursor is not moving when using laptop's touchpad). Also network is disconnected.

I have i-tec USB 3.0 Dual docking station Advance (U3HDMIDVIDOCK)

My laptop is Dell Inspiron 7537.

Please let me know if you need to collect any further information, I work in IT so no problem to get any dumps, logs, etc.

BTW, version 8.1 of DisplayLink drivers is great, better performance than 8.0 on Win10 Anniversary. Looking forward for another build with bugfixes.

black screen
Hi guys. I'm using Win 10 Anniversary, Dynadock U3.0 and this driver. Screen is sometimes black for 2 seconds. Mouse freezes for 2 secs before it happens. Afterwards all back to normal.
But the mouse lag is nearly gone with this alpha driver :) The dock is productively usable :)
Thanks so far for your efforts to produce a good driver.

Hi there, already posted this in the Windows Software forum, but this is perhaps a more relavent place...

I have also tried the 8.1 alpha and this issue where mouse lag and screen resets is still occurring.
From when I got the dock (Dell D3100), I started with DisplayLink 8.0 M2, then M3, now 8.1.782 Alpha. Issue still occurring.
I've only ever had Win 10 1607 on this device, so not sure if performance is/was better prior to this version.

Windows 10 Pro 1607
Dell Inspiron 13 - 7000 series
Core i7-7500 @2.7 GHz
Intel HD 620
Dell D3100 USB 3.0 Dock
1 external monitor (ASUS PB279Q) connected at 4K via DisplayPort on dock.

Mouse cursor is laggy most of the time - especially once more than a few applications are open.
External monitor goes black for 2-3 seconds about every 15 minutes during use (sometimes more frequently), as though it is resetting itself. The laptop monitor remains on. There is nothing to indicate that the monitor is 'disconnected'... the primary screen settings remain in place. If I am typing on the keyboard when this happens, which is also connected via the Dock, the text is still entered into the application and is waiting for me to continue when the screen comes back on.
WUDFHost.exe consumes 10-15% CPU continuously while the dock is connected and actions are occurring on the external monitor. When disconnected, this process is 0%.
Possibly related: audiodg.exe consumes 5-10% CPU continuously while the dock is connected.

Happy to provide more information if required.

Quick update since upgrading to the 8.1 M0 release today... all symptoms are still occurring, including the monitor 'resets', laggy mouse cursor and higher than expected CPU usage by WUDFHost.exe.

Any ideas or thoughts on this? Am happy to provide any further information if required.
