Lenovo LT1421 Shows Blank Screen on Mac

Looking at your logs, it looks like something went wrong in installing the driver.
The kernel extension is correctly installed, but the DisplayLink processes seem not running.
Could you please check the following files are installed:
/Library/PrivilegedHelperTools/DisplayLink/DisplayLinkManager
/Library/PrivilegedHelperTools/DisplayLink/DisplayLinkUserAgent

and

/Library/LaunchDaemons/com.displaylink.displaylinkmanager.plist
/Library/LaunchAgents/com.displaylink.useragent.plist
?
If one of these files are not installed, I would suggest to run the uninstaller, repair disk permissions using Disk Utility and then reinstall the DisplayLink driver. It should help also in case these files are there, maybe there are permission issues.
