I've installed newer NVIDIA drivers, but then am having trouble getting DisplayLink tray icon to show, so I've lost my 3rd monitor display. So in hindsight, perhaps the only way I had DisplayLink working was because it was working on Windows 7 x64 before the upgrade to Windows 8.
Anybody come up with a reliable way to run Windows 8 RTM and DisplayLink drivers yet?
Even the new driver for Windows 8 (out of beta), now version 7.0 Sep 7 2012:

failed for me with the same behavior: installs fast, screen never blanks, no tray icon (and no prompt to reboot).
While I did notice that the DisplayLinkManager is running, the Device manager has yellow exclamations on all ThinkPad USB 3.0 Dock entries under "Other Devices"
Nothing in this debugging guide helped:

Feels like I need to do some sort of manual cleanup (registry/files/etc) then a reboot perhaps?
FYI, Lenovo's new August 2012 driver for my Lenovo USB 3.0 dock won't even install on Windows 8 fyi:
