Unexpected Zooming of Application Windows on USB3 Display

Windows 8.1 Pro with Media Center (Official Release)
Plugable USB3-HDMI-DVI
DisplayLink 7.4 M2

After installing the Windows 8.1 update and the DisplayLink 7.4 M2 drivers my USB3 display works but when I display some (not all, e.g. the Task Manager appears as normal) application windows on the USB3 display they appear zoomed in at around 150%. When I move windows from my primary display to the USB3 one I can see this zooming happen once more than 50% of the window is shown in the USB3 display.

Any suggestions on how to resolve this as this significantly reduces the usefulness of my 2nd monitor.


I hadn’t knowingly changed anything but the problem went away when I selected the option: Let me choose one scaling level for all my displays

After logging out and back in again all looks right again.
