I'm having the same issues as well. I had done an upgrade to Windows 8 when it first started. After having other issues with the upgrade, I wiped the hard drive and did a clean install of Win 8 Pro. I installed the latest 7.0 M2 driver (downloaded from the DisplayLink website), hooked up the monitor, rebooted the machine when prompted to, and the screens began flickering on after reboot. Here is a video of what is happening:
