No Aero and very slow graphics after installing updated drive

[jwmoore39]

Windows told me that the latest driver was installed and I included that information in a previous message. I went to the Intel site for drivers and it tells me that

Product Detected Intel® HD Graphics
Current Driver Installed 8.16.11.8880
Your driver is current.

So the problem is not the Intel graphics driver.

The DisplayLink data collection said nothing about the NVIDIA driver, which Windows tells me is also up to date.

So the problem is not the graphics drivers. The problem is that somehow installing the latest DisplayLink software caused the graphics to slow down. I have seen this problem from others on the web and they claimed the only fix was to re-install Windows. My guess is that that would only work until I first plugged in the Kensington Multi-Display hardware and the DisplayLink driver was installed again. I don't have half a day to devote to re-installing Windows so I would like a fix from DisplayLink.
