I too am having an identical issue with the Dell Venue 8 Pro. I've tried a few different displaylink adapters, they all do the same thing when going to UAC.

Just observed that this happens as well when opening full screen Metro style apps as well.

Any updates?

Any updates to this issue?

James do you have any updates on this issue?

Hi,

This appears to be a Windows issue. We've seen the same thing happen with a directly attached display.

Thanks,
James

It does not happen with Surface Pro or Samsung Ativ700t. Doesn't sound like a Windows issue.

I am seeing this for Toshiba Encore tablet as well when connecting to Dell S2340T with usb displayport connection.
operating system: Win 8.1 (up to date)
DisplayLink Manager 7.6.56275.0

Can we have an update on this issue? Thanks!

Update?
 

Any updates? It is very annoying when the device screen rotates when you have it plugged in to the adapter.

You previously mentioned in post #7 that you were able to reproduce this.

This is not a windows issue as you mentioned later. I don't have this issue with any of the other tablets that I have tested.

Dell Latitude 10
Asus B121
Samsung Ativ 700T
Surface Pro 1
Surface Pro 2

I've seen the same issue on the new Plugable Pro 8 dock with a similar configuration as cmergel. I am using the external monitor as my only display and I have unchecked "Allow screen to auto-rotate" in the screen resolution properties. Any UAC prompt causes my display to change to Portrait (flipped).

My workaround was to disable the "Switch to Secure Desktop When Prompting for Elevation" policy setting as documented here

Once disabled, UAC prompt no longer auto-rotates the display. The screen does not dim when the UAC prompt appears, but it's an acceptable alternative to disabling UAC completely IMO.
