Hi,
Really need the logs to advise.
What graphics card make, model and driver version to you have installed?
Does this happen with the latest version of the graphics card driver?
Can you send the results of your notebook's system info file (run msinfo32.exe) or the results of dxdiag (run dxdiag.exe)?
What version of DisplayLink software do you have installed?
Does this happen with the latest version (7.6 M0)
Do you have another monitor you can try?
Some other tips for things to try can be found here:

Let me know how you get on.
Thanks,
James
