Hi,

Can you install the latest USB host controller driver from Intel?

You can find it here:

It's also worth installing the latest Intel graphics driver for your notebook which you can find here:

I'm having the same problem. The monitor works for a few minutes then flickers on and off as though it may not be drawing enough power or something else.
