Problem with DisplayLink Driver and Samsung Easy Settings Software

[c152driver]

Product: Plugable USB 3.0 to HDMI / DVI Adapter

My configuration:
SAMSUNG NP700Z7C-S01US Laptop running Windows 7 Professional 64-bit
This is an Nvidia Optimus machine with Intel integrated graphics and
an Nvidia 650M

After installing the DisplayLink driver, I get two identical crash
messages after logging in to Windows:

"igfxext Module has stopped working"

After some troubleshooting, I determined that this error was occurring
when the Samsung Easy Settings 1.1.1.2 software was starting. This is
the software that enables various keyboard shortcuts, such as
adjusting the keyboard backlight, toggling wireless off and on,
adjusting screen brightness, etc as well as providing access to other
hardware settings through a UI.

If I uninstall the Easy Settings software, the problem goes away.
However, this disables a lot of important functionality for the
laptop. Without the Easy Settings software, there is no away adjust
the keyboard backlight for example. Uninstalling the DisplayLink
driver also makes the problem go away.

Troubleshooting steps I have tried without success:

• Uninstalling and Reinstalling both the DisplayLink driver and Samsung Easy Settings
• Upgrading DisplayLink driver from 6.2 to 6.3
• Upgrading Intel video driver from 8.5.10.2618 to 8.5.10.2622
