Glutton for punishment

[smutek]

Figured I'd try making this work again, today. No luck, more wasted time.

I've got a Sabrant USB-2011 adapter, Macbook Pro, early 2011, fresh install of 10.9, and running the latest Display Link driver, version 2.1

2 Dell 2209WA Monitors.

Monitor 1 - connected via DVI to thunderbolt adapter.

Monitor 2 - connected via DVI to Sabrant USB-2011

The unit worked fine the first three days that I had it. I unplugged my laptop, took it out to go to a meeting, brought it back home, and the Sabrant connected monitor ceased working.

Monitor 1 Works.

Monitor 2 shows a black screen. The monitor will work for about a minute after uninstalling an reinstalling drivers, then goes black and will no longer work.

Monitor 2 shows up in system preferences / displays. The light on the monitor is blue, indicating it is connected. Also, note the attached screen shot - the desktop is visible (sabrant device on the right)



But - my screen remains black.

I've tried:

• Uninstalling and reinstalling the 2.1 drivers.
  
• Running the 2.1 beta driver
  
• Wiping my hard drive and rolling my system back to mountain Lion.
  
• Wiping my hard drive again and doing a fresh install of 10.9 Mavericks.

No luck on anything.

Any help or suggestions would be greatly appreciated.
