UM-710S on Win8...almost

[drueter]

I am trying to get my UM-710S running on my new Windows 8 machine.

I have the DisplayLink drivers and core software loaded (current versions, downloaded tonight).

I have current versions of the NVIDIA drivers installed (downloaded tonight)

I have followed the diagnostic steps on HOWTO: Debugging issues on Windows with DisplayLink--and everything seems fine.

The DisplayLink tray icon is working.

The LED and backlight on the Mimo respond to connect/disconnect of the monitor via the tray icon.

If the monitor is active and I stop the DisplayLink software, the monitor cycles through test patterns.

The only problem is that no image displays on the monitor. It is just a black screen (with backlight on).

I have tried uninstalling, rebooting, re-installing the driver several times.

I have used the diagnostic tool to capture a log--see attached file.

Any ideas on what to try next? It seems like it is so close to working... I hate to give up now.
