Samsung 940ux
 

After upgrading to Windows 10 I struggled to get these monitors working via Displaylink, but was successful in the end. Then they stopped working. After much searching I found this on the knowledgebase at http://support.displaylink.com/knowl...0-anniversary:

Up until 2009, a few devices based on DisplayLink technology included an auto install driver feature. This required the DisplayLink USB driver to switch the device from being a mass storage device to a video device. From Windows 10 Anniversary Update, we use the Microsoft USB driver, and this does not support the switching between a mass storage device and a video device. Therefore it is not possible to support these DisplayLink enabled devices from Windows 10 Anniversary Update.

Examples for affected devices are:
Samsung 940UX USB monitor

Is there a workaround or any alternative (other than going back to Windows 7)?

Other connection options
 

Might be worth seeing if your graphics card has a spare DVI or VGA connection. Had to order a long DVI cable for my wife's computer when her 940UX stopped working after the W10 update.

Hello Tony,
We do not know of a way round this with that USB driver, unfortunately.
The device stays in mass storage configuration as opposed to be in DisplayLink video configuration so the DisplayLink video driver is associated but not working.
On previous versions of Windows 10, we use a custom USB driver which allows switching the USB configuration.
Kind regards,
Alban

I can't understand
 

Sorry, i'm new. I can't understand if I can use my 3 monitor
Samsung 940UX USB monitor with display link driver on windows 10 last edition.

Do you have alternative to resolve this problem?
I must change monitor?

Thanks Tom

Hello Tom,
Unfortunately, today, the alternative is to use a USB->VGA/DVI adapter instead of built-in converter, if you wish to keep using that monitor.
Kind regards,
Alban
