"Duplicate these displays" no longer available after WIn 10 Anniversary update


#1

I recently received the Win 10 Anniversary Update on my laptop. I have my laptop connected to an external monitor through a Plugable UD3000 USB3.0 docking station. Prior to the update, I always had my DisplayLink settings setup to duplicate (mirror) my laptop display onto the external monitor. I’ve used this configuration for several years now without issue, but since taking the update, the “Duplicate these displays” option is no longer available in the display settings. All I get is “Extend these displays”, “Show only on 1” and “Show only on 2”. I’ve tried everything, including trying to reinstall the latest DisplayLink drivers from the plugable site, but nothing seems to work. Any ideas how to fix this? Thanks.

Hi Wayne, thanks for posting and I will be happy to help!

With the release of the Windows 10 Anniversary Update there has been a major change in how the DisplayLink drivers interacted with Windows 10 and as a result some systems no longer can set their second monitor to Duplicate mode when using DisplayLink-attached displays. We’ve mentioned this in an article after the Anniversary Update here --> http://plugable.com/2016/08/01/window… and DisplayLink has posted a knowledge base article here --> http://support.displaylink.com/knowle… and mentions some workaround that could be completed, but we cannot speak to their success. Unfortunately, there may not be much we can suggest to correct this behavior.

In our experience, we have seen this surface with older generation of AMD and Intel graphics processors ( the Intel HD Graphics 4000, for example ) and I would be happy to investigate some log files to help make sure that no stone goes un-turned regarding this issue. To help us do so please download and run our diagnostic utility PlugDebug --> http://plugable.com/support/plugdebug with everything connected. Please send us the log file to our direct support email address at support@plugable.com with ‘Ticket Number 159927’ in the subject line so we can match things up. We’ll examine the logs and go from there.

Thank you,

Thanks David. I’ve done as you asked and emailed the logs, but I fear the answer is already in your reply. My laptop does have an Intel HD Graphics 4000. It also has an NVidia GeForce GT635M, though, so not sure if that will make a difference? Thanks again.

Wayne
