I've been running a KVM switch with my monitor at 1920 x 1080 over VGA for over a year. Did a Windows Update on 12/11/12 which did the following:
- Update for Windows 7 for x64-based Systems (KB2779562)
- Security Update for Windows 7 for x64-based Systems (KB2779030)
- Cumulative Security Update for Internet Explorer 8 for Windows 7 for x64-based Systems (KB2761465)
- Windows Malicious Software Removal Tool x64 - December 2012 (KB890830)
- Security Update for Windows 7 for x64-based Systems (KB2753842)
- Security Update for Windows 7 for x64-based Systems (KB2758857)
- Security Update for Windows 7 for x64-based Systems (KB2770660)
After a restart, my extended monitor was dark. I attempted to reset the extended display configuration, and noticed my monitor was being detected as a Generic Non-PnP Monitor:
I uninstalled, downloaded new, and re-installed display drivers. Nothing. I attempted to unplug my monitor from the power for 15 minutes. Nothing. I followed some of the suggestions on this thread; specifically DanM's which suggested to create a new
*.inf file and replace that in Device Manager. Device Manager said the "best driver software for your device is already installed".
The only thing that works is when the monitor is directly attached to the laptop. This obviously is not what I want. My thought is to somehow remove the Generic Non-PnP Monitor from registry. How would I accomplish this and would this help? Any other suggestions?
