My configuration:
SAMSUNG NP700Z7C-S01US Laptop running Windows 7 Professional 64-bit
This is an Nvidia Optimus machine with Intel Ivy Bridge (HD4000) integrated graphics and an Nvidia 650M.
In order to support two external displays, I bought a Plugable USB 3.0 to HDMI / DVI Adapter which uses the DisplayLink USB video chipset.
After installing the DisplayLink driver, I get two identical crash
messages after logging in to Windows:

I reported this problem on the DisplayLink forum: Problem with DisplayLink Driver and Samsung Easy Settings Software
And received the following response:
Unfortunately this crash is in the Intel Graphics app. This app assumes that there are only the 2 Intel displays present on the PC, and crashes when it finds more displays connected. This needs to be fixed by Intel as we cannot work around this. They should not assume that there would only be the 2 Intel graphics cards connected to the PC.
We have raised this issue with Intel, but they have not been forthcoming with a fix.
So according to DisplayLink, the Intel driver has a bug which causes it to crash if there are additional displays connected. Is Intel planning a fix for this issue, or is there a work-around available?
