This module is provided by Intel and is connected to Intel display management. However it sometimes seems unstable in the presence of additional displays, eg those provided by DisplayLink.
The recommended work around to this issue is to prevent the igfxext app running at start up. This can be done by:
- Click on the Windows start button and run msconfig
- Click on the Startup tab
- Locate igfxext and uncheck the box to prevent it running at start up
- Click OK to apply the change and reboot.
