Screen Saver does not Start UD-3900

I have a UD-3900 connected to my Lenovo X1 Carbon Touch with an HP2511x monitor connected to the DVI port on the Hub. The X1 Carbon is running Windows 8.1 with the latest DisplayLink Manager Software is installed (7.5.52874.0). When connected to the HUB, the 2511x is configured to be my only display. As tests, I have also tried spanning the display across the laptop and external display and also disconnected the HUB entirely. In all cases, the screen saver now fails to start.
